+Node.js body parsing middleware.
+
+_This does not handle multipart bodies_, due to their complex and typically
+large nature. For multipart bodies, you may be interested in the following
+modules:
+
+  * [busboy](https://www.npmjs.org/package/busboy#readme) and
+    [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
+  * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
+    [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
+  * [formidable](https://www.npmjs.org/package/formidable#readme)
+  * [multer](https://www.npmjs.org/package/multer#readme)
+
+This module provides the following parsers:
+
+  * [JSON body parser](#bodyparserjsonoptions)
+  * [Raw body parser](#bodyparserrawoptions)
+  * [Text body parser](#bodyparsertextoptions)
+  * [URL-encoded form body parser](#bodyparserurlencodedoptions)
+
+Other body parsers you might be interested in:
+
+- [body](https://www.npmjs.org/package/body#readme)
+- [co-body](https://www.npmjs.org/package/co-body#readme)
+
+## Installation
+
+```sh
+$ npm install body-parser
+```
+
+## API
+
+```js
+var bodyParser = require('body-parser')
+```
+
+### bodyParser.json(options)
+
+Returns middleware that only parses `json`. This parser accepts any Unicode
+encoding of the body and supports automatic inflation of `gzip` and `deflate`
+encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`).
+
+#### Options
+
+The `json` function takes an option `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### reviver
+
+The `reviver` option is passed directly to `JSON.parse` as the second
+argument. You can find more information on this argument
+[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
+
+##### strict
+
+When set to `true`, will only accept arrays and objects; when `false` will
+accept anything `JSON.parse` accepts. Defaults to `true`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `json`), a mime type (like
+`application/json`), or a mime time with a wildcard (like `*/*` or `*/json`).
+If a function, the `type` option is called as `fn(req)` and the request is
+parsed if it returns a truthy value. Defaults to `json`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.raw(options)
+
+Returns middleware that parses all bodies as a `Buffer`. This parser
+supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a `Buffer` object
+of the body.
+
+#### Options
+
+The `raw` function takes an option `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `bin`), a mime type (like
+`application/octet-stream`), or a mime time with a wildcard (like `*/*` or
+`application/*`). If a function, the `type` option is called as `fn(req)`
+and the request is parsed if it returns a truthy value. Defaults to
+`application/octet-stream`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.text(options)
+
+Returns middleware that parses all bodies as a string. This parser supports
+automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` string containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a string of the
+body.
+
+#### Options
+
+The `text` function takes an option `options` object that may contain any of
+the following keys:
+
+##### defaultCharset
+
+Specify the default character set for the text content if the charset is not
+specified in the `Content-Type` header of the request. Defaults to `utf-8`.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `txt`), a mime type (like
+`text/plain`), or a mime time with a wildcard (like `*/*` or `text/*`).
+If a function, the `type` option is called as `fn(req)` and the request is
+parsed if it returns a truthy value. Defaults to `text/plain`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.urlencoded(options)
+
+Returns middleware that only parses `urlencoded` bodies. This parser accepts
+only UTF-8 encoding of the body and supports automatic inflation of `gzip`
+and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This object will contain
+key-value pairs, where the value can be a string or array (when `extended` is
+`false`), or any type (when `extended` is `true`).
+
+#### Options
+
+The `urlencoded` function takes an option `options` object that may contain
+any of the following keys:
+
+##### extended
+
+The `extended` option allows to choose between parsing the URL-encoded data
+with the `querystring` library (when `false`) or the `qs` library (when
+`true`). The "extended" syntax allows for rich objects and arrays to be
+encoded into the URL-encoded format, allowing for a JSON-like experience
+with URL-encoded. For more information, please
+[see the qs library](https://www.npmjs.org/package/qs#readme).
+
+Defaults to `true`, but using the default has been deprecated. Please
+research into the difference between `qs` and `querystring` and choose the
+appropriate setting.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### parameterLimit
+
+The `parameterLimit` option controls the maximum number of parameters that
+are allowed in the URL-encoded data. If a request contains more parameters
+than this value, a 413 will be returned to the client. Defaults to `1000`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `urlencoded`), a mime type (like
+`application/x-www-form-urlencoded`), or a mime time with a wildcard (like
+`*/x-www-form-urlencoded`). If a function, the `type` option is called as
+`fn(req)` and the request is parsed if it returns a truthy value. Defaults
+to `urlencoded`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+## Examples
+
+### express/connect top-level generic
+
+This example demonstrates adding a generic JSON and URL-encoded parser as a
+top-level middleware, which will parse the bodies of all incoming requests.
+This is the simplest setup.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse application/x-www-form-urlencoded
+app.use(bodyParser.urlencoded({ extended: false }))
+
+// parse application/json
+app.use(bodyParser.json())
+
+app.use(function (req, res) {
+  res.setHeader('Content-Type', 'text/plain')
+  res.write('you posted:\n')
+  res.end(JSON.stringify(req.body, null, 2))
+})
+```
+
+### express route-specific
+
+This example demonstrates adding body parsers specifically to the routes that
+need them. In general, this is the most recommend way to use body-parser with
+express.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// create application/json parser
+var jsonParser = bodyParser.json()
+
+// create application/x-www-form-urlencoded parser
+var urlencodedParser = bodyParser.urlencoded({ extended: false })
+
+// POST /login gets urlencoded bodies
+app.post('/login', urlencodedParser, function (req, res) {
+  if (!req.body) return res.sendStatus(400)
+  res.send('welcome, ' + req.body.username)
+})
+
+// POST /api/users gets JSON bodies
+app.post('/api/users', jsonParser, function (req, res) {
+  if (!req.body) return res.sendStatus(400)
+  // create user in req.body
+})
+```
+
+### change content-type for parsers
+
+All the parsers accept a `type` option which allows you to change the
+`Content-Type` that the middleware will parse.
+
+```js
+// parse various different custom JSON types as JSON
+app.use(bodyParser.json({ type: 'application/*+json' }))
+
+// parse some custom thing into a Buffer
+app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
+
+// parse an HTML body into a string
+app.use(bodyParser.text({ type: 'text/html' }))
+```

+
+Create and parse HTTP Content-Type header according to RFC 7231
+
+## Installation
+
+```sh
+$ npm install content-type
+```
+
+## API
+
+```js
+var contentType = require('content-type')
+```
+
+### contentType.parse(string)
+
+```js
+var obj = contentType.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a content type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (the type and subtype, always lower case).
+   Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter
+   always lower case). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the string is missing or invalid.
+
+### contentType.parse(req)
+
+```js
+var obj = contentType.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`contentType.parse(req.headers['content-type'])`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.parse(res)
+
+```js
+var obj = contentType.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`contentType.parse(res.getHeader('content-type'))`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.format(obj)
+
+```js
+var str = contentType.format({type: 'image/svg+xml'})
+```
+
+Format an object into a content type string. This will return a string of the
+content type for the given object with the following properties (examples are
+shown that produce the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of the
+   parameter will be lower-cased). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the object contains an invalid type or parameter names.

+# debug
+
+  tiny node.js debugging utility modelled after node core's debugging technique.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+ With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` format string goodies you're used to work fine. A unique color is selected per-function for visibility.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command. 
+ 
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+Then, run the program to be debugged as ususal.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+ If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect.compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Browser support
+
+  Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. Somewhere in the code on your page, include:
+
+```js
+window.myDebug = require("debug");
+```
+
+  ("debug" is a global object in the browser so we give this object a different name.) When your page is open in the browser, type the following in the console:
+
+```js
+myDebug.enable("worker:*")
+```
+
+  Refresh the page. Debug output will continue to be sent to the console until it is disabled by typing `myDebug.disable()` in the console.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+### stderr vs stdout
+
+You can set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally:
+
+Example _stderr.js_:
+
+```js
+var debug = require('../');
+var log = debug('app:log');
+
+// by default console.log is used
+log('goes to stdout!');
+
+var error = debug('app:error');
+// set this namespace to log via console.error
+error.log = console.error.bind(console); // don't forget to bind to console!
+error('goes to stderr');
+log('still goes to stdout!');
+
+// set all output to go via console.warn
+// overrides all per-namespace log settings
+debug.log = console.warn.bind(console);
+log('now goes to stderr via console.warn');
+error('still goes to stderr, but via console.warn now');
+```

It is highly suggested you use the\nname of your module as the namespace.\n\n### deprecate(message)\n\nCall this function from deprecated code to display a deprecation message.\nThis message will appear once per unique caller site. Caller site is the\nfirst call site in the stack in a different file from the caller of this\nfunction.\n\nIf the message is omitted, a message is generated for you based on the site\nof the `deprecate()` call and will display the name of the function called,\nsimilar to the name displayed in a stack trace.\n\n### deprecate.function(fn, message)\n\nCall this function to wrap a given function in a deprecation message on any\ncall to the function. An optional message can be supplied to provide a custom\nmessage.\n\n### deprecate.property(obj, prop, message)\n\nCall this function to wrap a given property on object in a deprecation message\non any accessing or setting of the property. An optional message can be supplied\nto provide a custom message.\n\nThe method must be called on the object where the property belongs (not\ninherited from the prototype).\n\nIf the property is a data descriptor, it will be converted to an accessor\ndescriptor in order to display the deprecation message.\n\n### process.on('deprecation', fn)\n\nThis module will allow easy capturing of deprecation errors by emitting the\nerrors as the type \"deprecation\" on the global `process`. If there are no\nlisteners for this type, the errors are written to STDERR as normal, but if\nthere are any listeners, nothing will be written to STDERR and instead only\nemitted. From there, you can write the errors in a different format or to a\nlogging source.\n\nThe error represents the deprecation and is emitted only once with the same\nrules as writing to STDERR. The error has the following properties:\n\n  - `message` - This is the message given by the library\n  - `name` - This is always `'DeprecationError'`\n  - `namespace` - This is the namespace the deprecation came from\n  - `stack` - This is the stack of the call to the deprecated thing\n\nExample `error.stack` output:\n\n```\nDeprecationError: my-cool-module deprecated oldfunction\n    at Object.<anonymous> ([eval]-wrapper:6:22)\n    at Module._compile (module.js:456:26)\n    at evalScript (node.js:532:25)\n    at startup (node.js:80:7)\n    at node.js:902:3\n```\n\n### process.env.NO_DEPRECATION\n\nAs a user of modules that are deprecated, the environment variable `NO_DEPRECATION`\nis provided as a quick solution to silencing deprecation warnings from being\noutput. The format of this is similar to that of `DEBUG`:\n\n```sh\n$ NO_DEPRECATION=my-module,othermod node app.js\n```\n\nThis will suppress deprecations from being output for \"my-module\" and \"othermod\".\nThe value is a list of comma-separated namespaces. To suppress every warning\nacross all namespaces, use the value `*` for a namespace.\n\nProviding the argument `--no-deprecation` to the `node` executable will suppress\nall deprecations (only available in Node.js 0.8 or higher).\n\n**NOTE** This will not suppress the deperecations given to any \"deprecation\"\nevent listeners, just the output to STDERR.\n\n### process.env.TRACE_DEPRECATION\n\nAs a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`\nis provided as a solution to getting more detailed location information in deprecation\nwarnings by including the entire stack trace. The format of this is the same as\n`NO_DEPRECATION`:\n\n```sh\n$ TRACE_DEPRECATION=my-module,othermod node app.js\n```\n\nThis will include stack traces for deprecations being output for \"my-module\" and\n\"othermod\". The value is a list of comma-separated namespaces. To trace every\nwarning across all namespaces, use the value `*` for a namespace.\n\nProviding the argument `--trace-deprecation` to the `node` executable will trace\nall deprecations (only available in Node.js 0.8 or higher).\n\n**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.\n\n## Display\n\n![message](files/message.png)\n\nWhen a user calls a function in your library that you mark deprecated, they\nwill see the following written to STDERR (in the given colors, similar colors\nand layout to the `debug` module):\n\n```\nbright cyan    bright yellow\n|              |          reset       cyan\n|              |          |           |\n▼              ▼          ▼           ▼\nmy-cool-module deprecated oldfunction [eval]-wrapper:6:22\n▲              ▲          ▲           ▲\n|              |          |           |\nnamespace      |          |           location of mycoolmod.oldfunction() call\n               |          deprecation message\n               the word \"deprecated\"\n```\n\nIf the user redirects their STDERR to a file or somewhere that does not support\ncolors, they see (similar layout to the `debug` module):\n\n```\nSun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22\n▲                             ▲              ▲          ▲              ▲\n|                             |              |          |              |\ntimestamp of message          namespace      |          |             location of mycoolmod.oldfunction() call\n                                             |          deprecation message\n                                             the word \"deprecated\"\n```\n\n## Examples\n\n### Deprecating all calls to a function\n\nThis will display a deprecated message about \"oldfunction\" being deprecated\nfrom \"my-module\" on STDERR.\n\n```js\nvar deprecate = require('depd')('my-cool-module')\n\n// message automatically derived from function name\n// Object.oldfunction\nexports.oldfunction = deprecate.function(function oldfunction() {\n  // all calls to function are deprecated\n})\n\n// specific message\nexports.oldfunction = deprecate.function(function () {\n  // all calls to function are deprecated\n}, 'oldfunction')\n```\n\n### Conditionally deprecating a function call\n\nThis will display a deprecated message about \"weirdfunction\" being deprecated\nfrom \"my-module\" on STDERR when called with less than 2 arguments.\n\n```js\nvar deprecate = require('depd')('my-cool-module')\n\nexports.weirdfunction = function () {\n  if (arguments.length < 2) {\n    // calls with 0 or 1 args are deprecated\n    deprecate('weirdfunction args < 2')\n  }\n}\n```\n\nWhen calling `deprecate` as a function, the warning is counted per call site\nwithin your own module, so you can display different deprecations depending\non different situations and the users will still get all the warnings:\n\n```js\nvar deprecate = require('depd')('my-cool-module')\n\nexports.weirdfunction = function () {\n  if (arguments.length < 2) {\n    // calls with 0 or 1 args are deprecated\n    deprecate('weirdfunction args < 2')\n  } else if (typeof arguments[0] !== 'string') {\n    // calls with non-string first argument are deprecated\n    deprecate('weirdfunction non-string first arg')\n  }\n}\n```\n\n### Deprecating property access\n\nThis will display a deprecated message about \"oldprop\" being deprecated\nfrom \"my-module\" on STDERR when accessed. A deprecation will be displayed\nwhen setting the value and when getting the value.\n\n```js\nvar deprecate = require('depd')('my-cool-module')\n\nexports.oldprop = 'something'\n\n// message automatically derives from property name\ndeprecate.property(exports, 'oldprop')\n\n// explicit message\ndeprecate.property(exports, 'oldprop', 'oldprop >= 0.10')\n```\n\n## License\n\n[MIT](LICENSE)\n\n[npm-version-image]: https://img.shields.io/npm/v/depd.svg?style=flat\n[npm-downloads-image]: https://img.shields.io/npm/dm/depd.svg?style=flat\n[npm-url]: https://npmjs.org/package/depd\n[travis-image]: https://img.shields.io/travis/dougwilson/nodejs-depd.svg?style=flat\n[travis-url]: https://travis-ci.org/dougwilson/nodejs-depd\n[coveralls-image]: https://img.shields.io/coveralls/dougwilson/nodejs-depd.svg?style=flat\n[coveralls-url]: https://coveralls.io/r/dougwilson/nodejs-depd?branch=master\n[node-image]: https://img.shields.io/node/v/depd.svg?style=flat\n[node-url]: http://nodejs.org/download/\n[gratipay-image]: https://img.shields.io/gratipay/dougwilson.svg?style=flat\n[gratipay-url]: https://www.gratipay.com/dougwilson/\n",

+## Pure JS character encoding conversion
+
+<!-- [![Build Status](https://secure.travis-ci.org/ashtuchkin/iconv-lite.png?branch=master)](http://travis-ci.org/ashtuchkin/iconv-lite) -->
+
+ * Doesn't need native code compilation. Works on Windows and in sandboxed environments like [Cloud9](http://c9.io).
+ * Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
+   [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
+ * Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
+ * Intuitive encode/decode API
+ * Streaming support for Node v0.10+
+ * Can extend Node.js primitives (buffers, streams) to support all iconv-lite encodings.
+ * In-browser usage via [Browserify](https://github.com/substack/node-browserify) (~180k gzip compressed with Buffer shim included).
+ * License: MIT.
+
+[![NPM Stats](https://nodei.co/npm/iconv-lite.png?downloads=true)](https://npmjs.org/packages/iconv-lite/)
+
+## Usage
+### Basic API
+```javascript
+var iconv = require('iconv-lite');
+
+// Convert from an encoded buffer to js string.
+str = iconv.decode(new Buffer([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
+
+// Convert from js string to an encoded buffer.
+buf = iconv.encode("Sample input string", 'win1251');
+
+// Check if encoding is supported
+iconv.encodingExists("us-ascii")
+```
+
+### Streaming API (Node v0.10+)
+```javascript
+
+// Decode stream (from binary stream to js strings)
+http.createServer(function(req, res) {
+    var converterStream = iconv.decodeStream('win1251');
+    req.pipe(converterStream);
+
+    converterStream.on('data', function(str) {
+        console.log(str); // Do something with decoded strings, chunk-by-chunk.
+    });
+});
+
+// Convert encoding streaming example
+fs.createReadStream('file-in-win1251.txt')
+    .pipe(iconv.decodeStream('win1251'))
+    .pipe(iconv.encodeStream('ucs2'))
+    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
+
+// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
+http.createServer(function(req, res) {
+    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
+        assert(typeof body == 'string');
+        console.log(body); // full request body string
+    });
+});
+```
+
+### Extend Node.js own encodings
+```javascript
+// After this call all Node basic primitives will understand iconv-lite encodings.
+iconv.extendNodeEncodings();
+
+// Examples:
+buf = new Buffer(str, 'win1251');
+buf.write(str, 'gbk');
+str = buf.toString('latin1');
+assert(Buffer.isEncoding('iso-8859-15'));
+Buffer.byteLength(str, 'us-ascii');
+
+http.createServer(function(req, res) {
+    req.setEncoding('big5');
+    req.collect(function(err, body) {
+        console.log(body);
+    });
+});
+
+fs.createReadStream("file.txt", "shift_jis");
+
+// External modules are also supported (if they use Node primitives, which they probably do).
+request = require('request');
+request({
+    url: "http://github.com/", 
+    encoding: "cp932"
+});
+
+// To remove extensions
+iconv.undoExtendNodeEncodings();
+```
+
+## Supported encodings
+
+ *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
+ *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap.
+ *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
+    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
+    Aliases like 'latin1', 'us-ascii' also supported.
+ *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2313, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
+
+See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
+
+Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
+
+Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
+
+
+## Encoding/decoding speed
+
+Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.10.26). 
+Note: your results may vary, so please always check on your hardware.
+
+    operation             iconv@2.1.4   iconv-lite@0.4.0
+    ----------------------------------------------------------
+    encode('win1251')     ~130 Mb/s     ~380 Mb/s
+    decode('win1251')     ~127 Mb/s     ~210 Mb/s
+
+
+## Notes
+
+When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
+Untranslatable characters are set to � or ?. No transliteration is currently supported.  
+Uses BOM to determine endianness, but doesn't remove it. Use ['strip-bom' module](https://github.com/sindresorhus/strip-bom).  
+Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see #65, #77).  
+
+## Testing
+
+```bash
+$ git clone git@github.com:ashtuchkin/iconv-lite.git
+$ cd iconv-lite
+$ npm install
+$ npm test
+    
+$ # To view performance:
+$ node test/performance.js

+    // All japanese encodings are based on JIS X set of standards:
+    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
+    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
+    //              Has several variations in 1978, 1983, 1990 and 1997.
+    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
+    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
+    //              2 planes, first is superset of 0208, second - revised 0212.
+    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
+
+    // Byte encodings are:
+    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
+    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
+    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
+    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
+    //               0x00-0x7F       - lower part of 0201
+    //               0x8E, 0xA1-0xDF - upper part of 0201
+    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
+    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
+    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
+    //               Used as-is in ISO2022 family.
+    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
+    //                0201-1976 Roman, 0208-1978, 0208-1983.
+    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
+    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
+    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
+    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
+    //
+    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

+
+Execute a callback when a request closes, finishes, or errors.
+
+## Install
+
+```sh
+$ npm install on-finished
+```
+
+## API
+
+```js
+var onFinished = require('on-finished')
+```
+
+### onFinished(res, listener)
+
+Attach a listener to listen for the response to finish. The listener will
+be invoked only once when the response finished. If the response finished
+to to an error, the first argument will contain the error. If the response
+has already finished, the listener will be invoked.
+
+Listening to the end of a response would be used to close things associated
+with the response, like open files.
+
+Listener is invoked as `listener(err, res)`.
+
+```js
+onFinished(res, function (err, res) {
+  // clean up open fds, etc.
+  // err contains the error is request error'd
+})
+```
+
+### onFinished(req, listener)
+
+Attach a listener to listen for the request to finish. The listener will
+be invoked only once when the request finished. If the request finished
+to to an error, the first argument will contain the error. If the request
+has already finished, the listener will be invoked.
+
+Listening to the end of a request would be used to know when to continue
+after reading the data.
+
+Listener is invoked as `listener(err, req)`.
+
+```js
+var data = ''
+
+req.setEncoding('utf8')
+res.on('data', function (str) {
+  data += str
+})
+
+onFinished(req, function (err, req) {
+  // data is read unless there is err
+})
+```
+
+### onFinished.isFinished(res)
+
+Determine if `res` is already finished. This would be useful to check and
+not even start certain operations if the response has already finished.
+
+### onFinished.isFinished(req)
+
+Determine if `req` is already finished. This would be useful to check and
+not even start certain operations if the request has already finished.
+
+### Example
+
+The following code ensures that file descriptors are always closed
+once the response finishes.
+
+```js
+var destroy = require('destroy')
+var http = require('http')
+var onFinished = require('on-finished')
+
+http.createServer(function onRequest(req, res) {
+  var stream = fs.createReadStream('package.json')
+  stream.pipe(res)
+  onFinished(res, function (err) {
+    destroy(stream)
+  })
+})
+```

+Get the first event in a set of event emitters and event pairs,

+
+## API
+
+```js

+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()
+```

+# qs
+
+A querystring parsing and stringifying library with some added security.
+
+[![Build Status](https://secure.travis-ci.org/hapijs/qs.svg)](http://travis-ci.org/hapijs/qs)
+
+Lead Maintainer: [Nathan LaFreniere](https://github.com/nlf)
+
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
+
+## Usage
+
+```javascript
+var Qs = require('qs');
+
+var obj = Qs.parse('a=c');    // { a: 'c' }
+var str = Qs.stringify(obj);  // 'a=c'
+```
+
+### Parsing Objects
+
+```javascript
+Qs.parse(string, [options]);
+```
+
+**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
+For example, the string `'foo[bar]=baz'` converts to:
+
+```javascript
+{
+  foo: {
+    bar: 'baz'
+  }
+}
+```
+
+URI encoded strings work too:
+
+```javascript
+Qs.parse('a%5Bb%5D=c');
+// { a: { b: 'c' } }
+```
+
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
+
+```javascript
+{
+  foo: {
+    bar: {
+      baz: 'foobarbaz'
+    }
+  }
+}
+```
+
+By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
+`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
+
+```javascript
+{
+  a: {
+    b: {
+      c: {
+        d: {
+          e: {
+            f: {
+              '[g][h][i]': 'j'
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+This depth can be overridden by passing a `depth` option to `Qs.parse(string, [options])`:
+
+```javascript
+Qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
+// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }
+```
+
+The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
+
+For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
+
+```javascript
+Qs.parse('a=b&c=d', { parameterLimit: 1 });
+// { a: 'b' }
+```
+
+An optional delimiter can also be passed:
+
+```javascript
+Qs.parse('a=b;c=d', { delimiter: ';' });
+// { a: 'b', c: 'd' }
+```
+
+Delimiters can be a regular expression too:
+
+```javascript
+Qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
+// { a: 'b', c: 'd', e: 'f' }
+```
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+Qs.parse('a[]=b&a[]=c');
+// { a: ['b', 'c'] }
+```
+
+You may specify an index as well:
+
+```javascript
+Qs.parse('a[1]=c&a[0]=b');
+// { a: ['b', 'c'] }
+```
+
+Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
+to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
+their order:
+
+```javascript
+Qs.parse('a[1]=b&a[15]=c');
+// { a: ['b', 'c'] }
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+Qs.parse('a[]=&a[]=b');
+// { a: ['', 'b'] }
+Qs.parse('a[0]=b&a[1]=&a[2]=c');
+// { a: ['b', '', 'c'] }
+```
+
+**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
+instead be converted to an object with the index as the key:
+
+```javascript
+Qs.parse('a[100]=b');
+// { a: { '100': 'b' } }
+```
+
+This limit can be overridden by passing an `arrayLimit` option:
+
+```javascript
+Qs.parse('a[1]=b', { arrayLimit: 0 });
+// { a: { '1': 'b' } }
+```
+
+To disable array parsing entirely, set `arrayLimit` to `-1`.
+
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+Qs.parse('a[0]=b&a[b]=c');
+// { a: { '0': 'b', b: 'c' } }
+```
+
+You can also create arrays of objects:
+
+```javascript
+Qs.parse('a[][b]=c');
+// { a: [{ b: 'c' }] }
+```
+
+### Stringifying
+
+```javascript
+Qs.stringify(object, [options]);
+```
+
+When stringifying, **qs** always URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+Qs.stringify({ a: 'b' });
+// 'a=b'
+Qs.stringify({ a: { b: 'c' } });
+// 'a%5Bb%5D=c'
+```
+
+Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
+
+When arrays are stringified, by default they are given explicit indices:
+
+```javascript
+Qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+You may override this by setting the `indices` option to `false`:
+
+```javascript
+Qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
+// 'a=b&a=c&a=d'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+Qs.stringify({ a: '' });
+// 'a='
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+Qs.stringify({ a: null, b: undefined });
+// 'a='
+```
+
+The delimiter may be overridden with stringify as well:

+  "readme": "# qs\n\nA querystring parsing and stringifying library with some added security.\n\n[![Build Status](https://secure.travis-ci.org/hapijs/qs.svg)](http://travis-ci.org/hapijs/qs)\n\nLead Maintainer: [Nathan LaFreniere](https://github.com/nlf)\n\nThe **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).\n\n## Usage\n\n```javascript\nvar Qs = require('qs');\n\nvar obj = Qs.parse('a=c');    // { a: 'c' }\nvar str = Qs.stringify(obj);  // 'a=c'\n```\n\n### Parsing Objects\n\n```javascript\nQs.parse(string, [options]);\n```\n\n**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.\nFor example, the string `'foo[bar]=baz'` converts to:\n\n```javascript\n{\n  foo: {\n    bar: 'baz'\n  }\n}\n```\n\nURI encoded strings work too:\n\n```javascript\nQs.parse('a%5Bb%5D=c');\n// { a: { b: 'c' } }\n```\n\nYou can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:\n\n```javascript\n{\n  foo: {\n    bar: {\n      baz: 'foobarbaz'\n    }\n  }\n}\n```\n\nBy default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like\n`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:\n\n```javascript\n{\n  a: {\n    b: {\n      c: {\n        d: {\n          e: {\n            f: {\n              '[g][h][i]': 'j'\n            }\n          }\n        }\n      }\n    }\n  }\n}\n```\n\nThis depth can be overridden by passing a `depth` option to `Qs.parse(string, [options])`:\n\n```javascript\nQs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });\n// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }\n```\n\nThe depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.\n\nFor similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:\n\n```javascript\nQs.parse('a=b&c=d', { parameterLimit: 1 });\n// { a: 'b' }\n```\n\nAn optional delimiter can also be passed:\n\n```javascript\nQs.parse('a=b;c=d', { delimiter: ';' });\n// { a: 'b', c: 'd' }\n```\n\nDelimiters can be a regular expression too:\n\n```javascript\nQs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });\n// { a: 'b', c: 'd', e: 'f' }\n```\n\n### Parsing Arrays\n\n**qs** can also parse arrays using a similar `[]` notation:\n\n```javascript\nQs.parse('a[]=b&a[]=c');\n// { a: ['b', 'c'] }\n```\n\nYou may specify an index as well:\n\n```javascript\nQs.parse('a[1]=c&a[0]=b');\n// { a: ['b', 'c'] }\n```\n\nNote that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number\nto create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving\ntheir order:\n\n```javascript\nQs.parse('a[1]=b&a[15]=c');\n// { a: ['b', 'c'] }\n```\n\nNote that an empty string is also a value, and will be preserved:\n\n```javascript\nQs.parse('a[]=&a[]=b');\n// { a: ['', 'b'] }\nQs.parse('a[0]=b&a[1]=&a[2]=c');\n// { a: ['b', '', 'c'] }\n```\n\n**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will\ninstead be converted to an object with the index as the key:\n\n```javascript\nQs.parse('a[100]=b');\n// { a: { '100': 'b' } }\n```\n\nThis limit can be overridden by passing an `arrayLimit` option:\n\n```javascript\nQs.parse('a[1]=b', { arrayLimit: 0 });\n// { a: { '1': 'b' } }\n```\n\nTo disable array parsing entirely, set `arrayLimit` to `-1`.\n\nIf you mix notations, **qs** will merge the two items into an object:\n\n```javascript\nQs.parse('a[0]=b&a[b]=c');\n// { a: { '0': 'b', b: 'c' } }\n```\n\nYou can also create arrays of objects:\n\n```javascript\nQs.parse('a[][b]=c');\n// { a: [{ b: 'c' }] }\n```\n\n### Stringifying\n\n```javascript\nQs.stringify(object, [options]);\n```\n\nWhen stringifying, **qs** always URI encodes output. Objects are stringified as you would expect:\n\n```javascript\nQs.stringify({ a: 'b' });\n// 'a=b'\nQs.stringify({ a: { b: 'c' } });\n// 'a%5Bb%5D=c'\n```\n\nExamples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.\n\nWhen arrays are stringified, by default they are given explicit indices:\n\n```javascript\nQs.stringify({ a: ['b', 'c', 'd'] });\n// 'a[0]=b&a[1]=c&a[2]=d'\n```\n\nYou may override this by setting the `indices` option to `false`:\n\n```javascript\nQs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });\n// 'a=b&a=c&a=d'\n```\n\nEmpty strings and null values will omit the value, but the equals sign (=) remains in place:\n\n```javascript\nQs.stringify({ a: '' });\n// 'a='\n```\n\nProperties that are set to `undefined` will be omitted entirely:\n\n```javascript\nQs.stringify({ a: null, b: undefined });\n// 'a='\n```\n\nThe delimiter may be overridden with stringify as well:\n\n```javascript\nQs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' });\n// 'a=b;c=d'\n```\n",

+
+Gets the entire buffer of a stream either as a `Buffer` or a string.
+Validates the stream's length against an expected length and maximum limit.
+Ideal for parsing request bodies.
+
+## API
+
+```js
+var getRawBody = require('raw-body')
+var typer      = require('media-typer')
+
+app.use(function (req, res, next) {
+  getRawBody(req, {
+    length: req.headers['content-length'],
+    limit: '1mb',
+    encoding: typer.parse(req.headers['content-type']).parameters.charset
+  }, function (err, string) {
+    if (err)
+      return next(err)
+
+    req.text = string
+    next()
+  })
+})
+```
+
+or in a Koa generator:
+
+```js
+app.use(function* (next) {
+  var string = yield getRawBody(this.req, {
+    length: this.length,
+    limit: '1mb',
+    encoding: this.charset
+  })
+})
+```
+
+### getRawBody(stream, [options], [callback])
+
+Returns a thunk for yielding with generators.
+
+Options:
+
+- `length` - The length length of the stream.
+  If the contents of the stream do not add up to this length,
+  an `400` error code is returned.
+- `limit` - The byte limit of the body.
+  If the body ends up being larger than this limit,
+  a `413` error code is returned.
+- `encoding` - The requested encoding.
+  By default, a `Buffer` instance will be returned.
+  Most likely, you want `utf8`.
+  You can use any type of encoding supported by [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme).
+
+You can also pass a string in place of options to just specify the encoding.
+
+`callback(err, res)`:
+
+- `err` - the following attributes will be defined if applicable:
+
+    - `limit` - the limit in bytes
+    - `length` and `expected` - the expected length of the stream
+    - `received` - the received bytes
+    - `encoding` - the invalid encoding
+    - `status` and `statusCode` - the corresponding status code for the error
+    - `type` - either `entity.too.large`, `request.size.invalid`, `stream.encoding.set`, or `encoding.unsupported`
+
+- `res` - the result, either as a `String` if an encoding was set or a `Buffer` otherwise.
+
+If an error occurs, the stream will be paused, everything unpiped,
+and you are responsible for correctly disposing the stream.
+For HTTP requests, no handling is required if you send a response.
+For streams that use file descriptors, you should `stream.destroy()` or `stream.close()` to prevent leaks.

+
+Infer the content-type of a request.
+
+### Install
+
+```sh
+$ npm install type-is
+```
+
+## API
+
+```js
+var http = require('http')
+var is   = require('type-is')
+
+http.createServer(function (req, res) {
+  var istext = is(req, ['text/*'])
+  res.end('you ' + (istext ? 'sent' : 'did not send') + ' me text')
+})
+```
+
+### type = is(request, types)
+
+`request` is the node HTTP request. `types` is an array of types.
+
+```js
+// req.headers.content-type = 'application/json'
+
+is(req, ['json'])             // 'json'
+is(req, ['html', 'json'])     // 'json'
+is(req, ['application/*'])    // 'application/json'
+is(req, ['application/json']) // 'application/json'
+
+is(req, ['html']) // false
+```
+
+### type = is.is(mediaType, types)
+
+`mediaType` is the [media type](https://tools.ietf.org/html/rfc6838) string. `types` is an array of types.
+
+```js
+var mediaType = 'application/json'
+
+is.is(mediaType, ['json'])             // 'json'
+is.is(mediaType, ['html', 'json'])     // 'json'
+is.is(mediaType, ['application/*'])    // 'application/json'
+is.is(mediaType, ['application/json']) // 'application/json'
+
+is.is(mediaType, ['html']) // false
+```
+
+### Each type can be:
+
+- An extension name such as `json`. This name will be returned if matched.
+- A mime type such as `application/json`.
+- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`. The full mime type will be returned if matched.
+- A suffix such as `+json`. This can be combined with a wildcard such as `*/vnd+json` or `application/*+json`. The full mime type will be returned if matched.
+
+`false` will be returned if no type matches.
+
+`null` will be returned if the request does not have a body.
+
+## Examples
+
+#### Example body parser
+
+```js
+var is = require('type-is');
+
+function bodyParser(req, res, next) {
+  if (!is.hasBody(req)) {
+    return next()
+  }
+
+  switch (is(req, ['urlencoded', 'json', 'multipart'])) {
+    case 'urlencoded':
+      // parse urlencoded body
+      throw new Error('implement urlencoded body parsing')
+      break
+    case 'json':
+      // parse json body
+      throw new Error('implement json body parsing')
+      break
+    case 'multipart':
+      // parse multipart body
+      throw new Error('implement multipart body parsing')
+      break
+    default:
+      // 415 error code
+      res.statusCode = 415
+      res.end()
+      return
+  }
+}

+Simple RFC 6838 media type parser
+
+## Installation
+
+```sh
+$ npm install media-typer
+```
+
+## API
+
+```js
+var typer = require('media-typer')
+```
+
+### typer.parse(string)
+
+```js
+var obj = typer.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a media type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The type of the media type (always lower case). Example: `'image'`
+
+ - `subtype`: The subtype of the media type (always lower case). Example: `'svg'`
+
+ - `suffix`: The suffix of the media type (always lower case). Example: `'xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter always lower case). Example: `{charset: 'utf-8'}`
+
+### typer.parse(req)
+
+```js
+var obj = typer.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`typer.parse(req.headers['content-type'])`.
+
+### typer.parse(res)
+
+```js
+var obj = typer.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`typer.parse(res.getHeader('content-type'))`.
+
+### typer.format(obj)
+
+```js
+var obj = typer.format({type: 'image', subtype: 'svg', suffix: 'xml'})
+```
+
+Format an object into a media type string. This will return a string of the
+mime type for the given object. For the properties of the object, see the
+documentation for `typer.parse(string)`.

+# mime-db
+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]
+[![Node.js Version][node-image]][node-url]
+[![Build Status][travis-image]][travis-url]
+[![Coverage Status][coveralls-image]][coveralls-url]
+
+This is a database of all mime types.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+If you're crazy enough to use this in the browser,
+you can just grab the JSON file:
+
+```
+https://cdn.rawgit.com/jshttp/mime-db/master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db');
+
+// grab data on .js files
+var data = db['application/javascript'];
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type is can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom.json` or
+`src/custom-suffix.json`.
+
+To update the build, run `npm run update`.
+
+## Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.

+# bower-registry-client [![Build Status](https://travis-ci.org/bower/registry-client.png?branch=master)](https://travis-ci.org/bower/registry-client)
+
+> Provides easy interaction with the Bower registry
+
+
+## Install
+
+```
+$ npm install --save bower-registry-client
+```
+
+
+## Usage
+
+```js
+var RegistryClient = require('bower-registry-client');
+var registry = new RegistryClient(options, logger);
+```
+
+The `logger` is optional and is expected to be an instance of the bower [logger](https://github.com/bower/logger).   
+Available constructor options:
+
+- `cache`: the cache folder to use for some operations; using null will disable persistent cache (defaults to bower registry cache folder)
+- `registry.search`: an array of registry search endpoints (defaults to the Bower server)
+- `registry.register`: the endpoint to use when registering packages (defaults to the Bower server)
+- `registry.publish`: the endpoint to use when publishing packages (defaults to the Bower server)
+- `ca.search`: an array of CA certificates for each registry.search (defaults to null).
+- `ca.register`: the CA certificate for registry.register
+- `ca.publish`: the CA certificate for registry.publish
+- `proxy`: the proxy to use for http requests (defaults to null)
+- `httpsProxy`: the proxy to use for https requests (defaults to null)
+- `strictSsl`: whether or not to do SSL key validation when making requests via https (defaults to true).
+- `userAgent`: the user agent to use for the requests (defaults to null)
+- `timeout`: the timeout for the requests to finish (defaults to 60000)
+- `force`: If set to true, cache will be bypassed and remotes will always be hit (defaults to false).
+- `offline`: If set to true, only the cache will be used (defaults to false).
+
+
+Note that `force` and `offline` are mutually exclusive.
+The cache will speedup operations such as `list`, `lookup` and `search`.
+Different operations may have different cache expiration times.
+
+
+#### .lookup(name, callback)
+
+Looks the registry for the package `name`,
+
+```js
+registry.lookup('jquery', function (err, entry) {
+    if (err) {
+        console.error(err.message);
+        return;
+    }
+
+    // For now resp.type is always 'alias'
+    console.log('type', entry.type);
+    console.log('url', entry.url);
+});
+```
+
+#### .register(name, url, callback)
+
+Registers a package in the registry.
+
+```js
+registry.register('my-package', 'git://github.com/my-org/my-package.git', function (err, pkg) {
+    if (err) {
+        console.error(err.message);
+        return;
+    }
+
+    console.log('name', pkg.name);
+    console.log('url: ', pkg.url);
+});
+```
+
+#### .search(str, callback)
+
+Searches the registry.
+
+```js
+registry.search('jquery', function (err, results) {
+    if (err) {
+        console.error(err.message);
+        return;
+    }
+
+    results.forEach(function (pkg) {
+        console.log('name', pkg.name);
+        console.log('url', pkg.url);
+    });
+});
+```
+
+#### .clearCache(name, callback)
+
+Clears the persistent and runtime cache associated with the `name` package.   
+If `name` is null, clears the cache for every package.
+
+Note that in most cases, you don't need to clear the cache since it has
+self expiration times.
+
+```js
+// Clear jquery cache
+registry.clearCache('jquery', function (err) {
+    if (err) {
+        console.error(err.message);
+        return;
+    }
+
+    console.log('Done');
+});
+
+// Clear all cache
+registry.clearCache(function (err) {
+    if (err) {
+        console.error(err.message);
+        return;
+    }
+
+    console.log('Done');
+});
+```
+
+
+#### .resetCache()
+
+Clears the in-memory cache used to speed up the instance.
+
+Note that in most cases, you don't need to clear the runtime cache since it has
+self expiration times.
+Might be useful if you use this module in long-living programs.
+
+```js
+registry.resetCache();
+```
+
+#### #clearRuntimeCache()
+
+Clears the in-memory cache used to speed up the whole module.
+This clears the static in-memory cache as well as in-memory cache used by instances.
+
+Note that in edge cases, some instance's in-memory cache might be skipped.
+If that's a problem, you should create fresh instances instead.
+
+```js
+RegistryClient.clearRuntimeCache();
+```

+# This is an OPEN Open Source Project
+
+-----------------------------------------
+
+## What?
+
+Individuals making significant and valuable contributions are given
+commit-access to the project to contribute as they see fit. This project is
+more like an open wiki than a standard guarded open source project.
+
+## Rules
+
+There are a few basic ground-rules for contributors:
+
+1. **No `--force` pushes** or modifying the Git history in any way.
+1. **Non-master branches** ought to be used for ongoing work.
+1. **External API changes and significant modifications** ought to be subject
+   to an **internal pull-request** to solicit feedback from other contributors.
+1. Internal pull-requests to solicit feedback are *encouraged* for any other
+   non-trivial contribution but left to the discretion of the contributor.
+1. For significant changes wait a full 24 hours before merging so that active
+   contributors who are distributed throughout the world have a chance to weigh
+   in.
+1. Contributors should attempt to adhere to the prevailing code-style.
+1. Run `npm test` locally before submitting your PR, to catch any easy to miss
+   style & testing issues.  To diagnose test failures, there are two ways to
+   run a single test file:
+     - `node_modules/.bin/taper tests/test-file.js` - run using the default
+       [`taper`](https://github.com/nylen/taper) test reporter.
+     - `node tests/test-file.js` - view the raw
+       [tap](https://testanything.org/) output.
+
+
+## Releases
+
+Declaring formal releases remains the prerogative of the project maintainer.
+
+## Changes to this arrangement
+
+This is an experiment and feedback is welcome! This document may also be
+subject to pull-requests or changes by contributors where you believe you have
+something valuable to add or change.

+# Request — Simplified HTTP client
+[![NPM](https://nodei.co/npm/request.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/request/)
+
+[![Gitter](https://badges.gitter.im/Join Chat.svg)](https://gitter.im/request/request?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+## Super simple to use
+
+Request is designed to be the simplest way possible to make http calls. It supports HTTPS and follows redirects by default.
+
+```javascript
+var request = require('request');
+request('http://www.google.com', function (error, response, body) {
+  if (!error && response.statusCode == 200) {
+    console.log(body) // Print the google web page.
+  }
+})
+```
+
+## Streaming
+
+You can stream any response to a file stream.
+
+```javascript
+request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
+```
+
+You can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).
+
+```javascript
+fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))
+```
+
+Request can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.
+
+```javascript
+request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))
+```
+
+Request emits a "response" event when a response is received. The `response` argument will be an instance of [http.IncomingMessage](http://nodejs.org/api/http.html#http_http_incomingmessage).
+
+```javascript
+request
+  .get('http://google.com/img.png')
+  .on('response', function(response) {
+    console.log(response.statusCode) // 200
+    console.log(response.headers['content-type']) // 'image/png'
+  })
+  .pipe(request.put('http://mysite.com/img.png'))
+```
+
+To easily handle errors when streaming requests, listen to the `error` event before piping:
+
+```javascript
+request
+  .get('http://mysite.com/doodle.png')
+  .on('error', function(err) {
+    console.log(err)
+  })
+  .pipe(fs.createWriteStream('doodle.png'))
+```
+
+Now let’s get fancy.
+
+```javascript
+http.createServer(function (req, resp) {
+  if (req.url === '/doodle.png') {
+    if (req.method === 'PUT') {
+      req.pipe(request.put('http://mysite.com/doodle.png'))
+    } else if (req.method === 'GET' || req.method === 'HEAD') {
+      request.get('http://mysite.com/doodle.png').pipe(resp)
+    }
+  }
+})
+```
+
+You can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:
+
+```javascript
+http.createServer(function (req, resp) {
+  if (req.url === '/doodle.png') {
+    var x = request('http://mysite.com/doodle.png')
+    req.pipe(x)
+    x.pipe(resp)
+  }
+})
+```
+
+And since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)
+
+```javascript
+req.pipe(request('http://mysite.com/doodle.png')).pipe(resp)
+```
+
+Also, none of this new functionality conflicts with requests previous features, it just expands them.
+
+```javascript
+var r = request.defaults({'proxy':'http://localproxy.com'})
+
+http.createServer(function (req, resp) {
+  if (req.url === '/doodle.png') {
+    r.get('http://google.com/doodle.png').pipe(resp)
+  }
+})
+```
+
+You can still use intermediate proxies, the requests will still follow HTTP forwards, etc.
+
+## Proxies
+
+If you specify a `proxy` option, then the request (and any subsequent
+redirects) will be sent via a connection to the proxy server.
+
+If your endpoint is an `https` url, and you are using a proxy, then
+request will send a `CONNECT` request to the proxy server *first*, and
+then use the supplied connection to connect to the endpoint.
+
+That is, first it will make a request like:
+
+```
+HTTP/1.1 CONNECT endpoint-server.com:80
+Host: proxy-server.com
+User-Agent: whatever user agent you specify
+```
+
+and then the proxy server make a TCP connection to `endpoint-server`
+on port `80`, and return a response that looks like:
+
+```
+HTTP/1.1 200 OK
+```
+
+At this point, the connection is left open, and the client is
+communicating directly with the `endpoint-server.com` machine.
+
+See [the wikipedia page on HTTP Tunneling](http://en.wikipedia.org/wiki/HTTP_tunnel)
+for more information.
+
+By default, when proxying `http` traffic, request will simply make a
+standard proxied `http` request.  This is done by making the `url`
+section of the initial line of the request a fully qualified url to
+the endpoint.
+
+For example, it will make a single request that looks like:
+
+```
+HTTP/1.1 GET http://endpoint-server.com/some-url
+Host: proxy-server.com
+Other-Headers: all go here
+
+request body or whatever
+```
+
+Because a pure "http over http" tunnel offers no additional security
+or other features, it is generally simpler to go with a
+straightforward HTTP proxy in this case.  However, if you would like
+to force a tunneling proxy, you may set the `tunnel` option to `true`.
+
+If you are using a tunneling proxy, you may set the
+`proxyHeaderWhiteList` to share certain headers with the proxy.
+
+You can also set the `proxyHeaderExclusiveList` to share certain
+headers only with the proxy and not with destination host.
+
+By default, this set is:
+
+```
+accept
+accept-charset
+accept-encoding
+accept-language
+accept-ranges
+cache-control
+content-encoding
+content-language
+content-length
+content-location
+content-md5
+content-range
+content-type
+connection
+date
+expect
+max-forwards
+pragma
+proxy-authorization
+referer
+te
+transfer-encoding
+user-agent
+via
+```
+
+Note that, when using a tunneling proxy, the `proxy-authorization`
+header and any headers from custom `proxyHeaderExclusiveList` are
+*never* sent to the endpoint server, but only to the proxy server.
+
+### Controlling proxy behaviour using environment variables
+
+The following environment variables are respected by `request`:
+
+ * `HTTP_PROXY` / `http_proxy`
+ * `HTTPS_PROXY` / `https_proxy`
+ * `NO_PROXY` / `no_proxy`
+
+When `HTTP_PROXY` / `http_proxy` are set, they will be used to proxy non-SSL requests that do not have an explicit `proxy` configuration option present. Similarly, `HTTPS_PROXY` / `https_proxy` will be respected for SSL requests that do not have an explicit `proxy` configuration option. It is valid to define a proxy in one of the environment variables, but then override it for a specific request, using the `proxy` configuration option. Furthermore, the `proxy` configuration option can be explicitly set to false / null to opt out of proxying altogether for that request.
+
+`request` is also aware of the `NO_PROXY`/`no_proxy` environment variables. These variables provide a granular way to opt out of proxying, on a per-host basis. It should contain a comma separated list of hosts to opt out of proxying. It is also possible to opt of proxying when a particular destination port is used. Finally, the variable may be set to `*` to opt out of the implicit proxy configuration of the other environment variables.
+
+Here's some examples of valid `no_proxy` values:
+
+ * `google.com` - don't proxy HTTP/HTTPS requests to Google.
+ * `google.com:443` - don't proxy HTTPS requests to Google, but *do* proxy HTTP requests to Google.
+ * `google.com:443, yahoo.com:80` - don't proxy HTTPS requests to Google, and don't proxy HTTP requests to Yahoo!
+ * `*` - ignore `https_proxy`/`http_proxy` environment variables altogether.
+
+## UNIX Socket
+
+`request` supports making requests to [UNIX Domain Sockets](http://en.wikipedia.org/wiki/Unix_domain_socket). To make one, use the following URL scheme:
+
+```javascript
+/* Pattern */ 'http://unix:SOCKET:PATH'
+/* Example */ request.get('http://unix:/absolute/path/to/unix.socket:/request/path')
+```
+
+Note: The `SOCKET` path is assumed to be absolute to the root of the host file system.
+
+
+## Forms
+
+`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.
+
+#### application/x-www-form-urlencoded (URL-Encoded Forms)
+
+URL-encoded forms are simple.
+
+```javascript
+request.post('http://service.com/upload', {form:{key:'value'}})
+// or
+request.post('http://service.com/upload').form({key:'value'})
+// or
+request.post({url:'http://service.com/upload', form: {key:'value'}}, function(err,httpResponse,body){ /* ... */ })
+```
+
+#### multipart/form-data (Multipart Form Uploads)
+
+For `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). For the most cases, you can pass your upload form data via the `formData` option.
+
+
+```javascript
+var formData = {
+  // Pass a simple key-value pair
+  my_field: 'my_value',
+  // Pass data via Buffers
+  my_buffer: new Buffer([1, 2, 3]),
+  // Pass data via Streams
+  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
+  // Pass multiple values /w an Array
+  attachments: [
+    fs.createReadStream(__dirname + '/attachment1.jpg'),
+    fs.createReadStream(__dirname + '/attachment2.jpg')
+  ],
+  // Pass optional meta-data with an 'options' object with style: {value: DATA, options: OPTIONS}
+  // Use case: for some types of streams, you'll need to provide "file"-related information manually.
+  // See the `form-data` README for more information about options: https://github.com/felixge/node-form-data
+  custom_file: {
+    value:  fs.createReadStream('/dev/urandom'),
+    options: {
+      filename: 'topsecret.jpg',
+      contentType: 'image/jpg'
+    }
+  }
+};
+request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) {
+  if (err) {
+    return console.error('upload failed:', err);
+  }
+  console.log('Upload successful!  Server responded with:', body);
+});
+```
+
+For advanced cases, you can access the form-data object itself via `r.form()`. This can be modified until the request is fired on the next cycle of the event-loop. (Note that this calling `form()` will clear the currently set form data for that request.)
+
+```javascript
+// NOTE: Advanced use-case, for normal use see 'formData' usage above
+var r = request.post('http://service.com/upload', function optionalCallback(err, httpResponse, body) { // ...
+
+var form = r.form();
+form.append('my_field', 'my_value');
+form.append('my_buffer', new Buffer([1, 2, 3]));
+form.append('custom_file', fs.createReadStream(__dirname + '/unicycle.jpg'), {filename: 'unicycle.jpg'});
+```
+See the [form-data README](https://github.com/felixge/node-form-data) for more information & examples.
+
+#### multipart/related
+
+Some variations in different HTTP implementations require a newline/CRLF before, after, or both before and after the boundary of a `multipart/related` request (using the multipart option). This has been observed in the .NET WebAPI version 4.0. You can turn on a boundary preambleCRLF or postamble by passing them as `true` to your request options.
+
+```javascript
+  request({
+    method: 'PUT',
+    preambleCRLF: true,
+    postambleCRLF: true,
+    uri: 'http://service.com/upload',
+    multipart: [
+      {
+        'content-type': 'application/json'
+        body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
+      },
+      { body: 'I am an attachment' },
+      { body: fs.createReadStream('image.png') }
+    ],
+    // alternatively pass an object containing additional options
+    multipart: {
+      chunked: false,
+      data: [
+        {
+          'content-type': 'application/json',
+          body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
+        },
+        { body: 'I am an attachment' }
+      ]
+    }
+  },
+  function (error, response, body) {
+    if (error) {
+      return console.error('upload failed:', error);
+    }
+    console.log('Upload successful!  Server responded with:', body);
+  })
+```
+
+
+## HTTP Authentication
+
+```javascript
+request.get('http://some.server.com/').auth('username', 'password', false);
+// or
+request.get('http://some.server.com/', {
+  'auth': {
+    'user': 'username',
+    'pass': 'password',
+    'sendImmediately': false
+  }
+});
+// or
+request.get('http://some.server.com/').auth(null, null, true, 'bearerToken');
+// or
+request.get('http://some.server.com/', {
+  'auth': {
+    'bearer': 'bearerToken'
+  }
+});
+```
+
+If passed as an option, `auth` should be a hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional).  The method form takes parameters `auth(username, password, sendImmediately)`.
+
+`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent.  If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method).
+
+Note that you can also use for basic authentication a trick using the URL itself, as specified in [RFC 1738](http://www.ietf.org/rfc/rfc1738.txt).
+Simply pass the `user:password` before the host with an `@` sign.
+
+```javascript
+var username = 'username',
+    password = 'password',
+    url = 'http://' + username + ':' + password + '@some.server.com';
+
+request({url: url}, function (error, response, body) {
+   // Do more stuff with 'body' here
+});
+```
+
+Digest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail.
+
+Bearer authentication is supported, and is activated when the `bearer` value is available. The value may be either a `String` or a `Function` returning a `String`. Using a function to supply the bearer token is particularly useful if used in conjuction with `defaults` to allow a single function to supply the last known token at the time or sending a request or to compute one on the fly.
+
+## OAuth Signing
+
+[OAuth version 1.0](https://tools.ietf.org/html/rfc5849) is supported.  The
+default signing algorithm is
+[HMAC-SHA1](https://tools.ietf.org/html/rfc5849#section-3.4.2):
+
+```javascript
+// Twitter OAuth
+var qs = require('querystring')
+  , oauth =
+    { callback: 'http://mysite.com/callback/'
+    , consumer_key: CONSUMER_KEY
+    , consumer_secret: CONSUMER_SECRET
+    }
+  , url = 'https://api.twitter.com/oauth/request_token'
+  ;
+request.post({url:url, oauth:oauth}, function (e, r, body) {
+  // Ideally, you would take the body in the response
+  // and construct a URL that a user clicks on (like a sign in button).
+  // The verifier is only available in the response after a user has
+  // verified with twitter that they are authorizing your app.
+  var access_token = qs.parse(body)
+    , oauth =
+      { consumer_key: CONSUMER_KEY
+      , consumer_secret: CONSUMER_SECRET
+      , token: access_token.oauth_token
+      , verifier: access_token.oauth_verifier
+      }
+    , url = 'https://api.twitter.com/oauth/access_token'
+    ;
+  request.post({url:url, oauth:oauth}, function (e, r, body) {
+    var perm_token = qs.parse(body)
+      , oauth =
+        { consumer_key: CONSUMER_KEY
+        , consumer_secret: CONSUMER_SECRET
+        , token: perm_token.oauth_token
+        , token_secret: perm_token.oauth_token_secret
+        }
+      , url = 'https://api.twitter.com/1.1/users/show.json?'
+      , params =
+        { screen_name: perm_token.screen_name
+        , user_id: perm_token.user_id
+        }
+      ;
+    url += qs.stringify(params)
+    request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {
+      console.log(user)
+    })
+  })
+})
+```
+
+For [RSA-SHA1 signing](https://tools.ietf.org/html/rfc5849#section-3.4.3), make
+the following changes to the OAuth options object:
+* Pass `signature_method : 'RSA-SHA1'`
+* Instead of `consumer_secret`, specify a `private_key` string in
+  [PEM format](http://how2ssl.com/articles/working_with_pem_files/)
+
+## Custom HTTP Headers
+
+HTTP Headers, such as `User-Agent`, can be set in the `options` object.
+In the example below, we call the github API to find out the number
+of stars and forks for the request repository. This requires a
+custom `User-Agent` header as well as https.
+
+```javascript
+var request = require('request');
+
+var options = {
+	url: 'https://api.github.com/repos/request/request',
+	headers: {
+		'User-Agent': 'request'
+	}
+};
+
+function callback(error, response, body) {
+	if (!error && response.statusCode == 200) {
+		var info = JSON.parse(body);
+		console.log(info.stargazers_count + " Stars");
+		console.log(info.forks_count + " Forks");
+	}
+}
+
+request(options, callback);
+```
+
+## TLS/SSL Protocol
+
+TLS/SSL Protocol options, such as `cert`, `key` and `passphrase`, can be
+set in the `agentOptions` property of the `options` object.
+In the example below, we call an API requires client side SSL certificate
+(in PEM format) with passphrase protected private key (in PEM format) and disable the SSLv3 protocol:
+
+```javascript
+var fs = require('fs')
+    , path = require('path')
+    , certFile = path.resolve(__dirname, 'ssl/client.crt')
+    , keyFile = path.resolve(__dirname, 'ssl/client.key')
+    , request = require('request');
+
+var options = {
+    url: 'https://api.some-server.com/',
+    agentOptions: {
+        cert: fs.readFileSync(certFile),
+        key: fs.readFileSync(keyFile),
+        // Or use `pfx` property replacing `cert` and `key` when using private key, certificate and CA certs in PFX or PKCS12 format:
+        // pfx: fs.readFileSync(pfxFilePath),
+        passphrase: 'password',
+        securityOptions: 'SSL_OP_NO_SSLv3'
+    }
+};
+
+request.get(options);
+```
+
+It is able to force using SSLv3 only by specifying `secureProtocol`:
+
+```javascript
+request.get({
+    url: 'https://api.some-server.com/',
+    agentOptions: {
+        secureProtocol: 'SSLv3_method'
+    }
+});
+```
+
+It is possible to accept other certificates than those signed by generally allowed Certificate Authorities (CAs).
+This can be useful, for example,  when using self-signed certificates.
+To allow a different certificate, you can specify the signing CA by adding the contents of the CA's certificate file to the `agentOptions`:
+
+```javascript
+request.get({
+    url: 'https://api.some-server.com/',
+    agentOptions: {
+        ca: fs.readFileSync('ca.cert.pem')
+    }
+});
+```
+
+## request(options, callback)
+
+The first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.
+
+* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`
+* `qs` - object containing querystring values to be appended to the `uri`
+* `useQuerystring` - If true, use `querystring` to stringify and parse
+  querystrings, otherwise use `qs` (default: `false`).  Set this option to
+  `true` if you need arrays to be serialized as `foo=bar&foo=baz` instead of the
+  default `foo[0]=bar&foo[1]=baz`.
+* `method` - http method (default: `"GET"`)
+* `headers` - http headers (default: `{}`)
+* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`, unless `json` is `true`. If `json` is `true`, then `body` must be a JSON-serializable object.
+* `form` - when passed an object or a querystring, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded` header. When passed no options, a `FormData` instance is returned (and is piped to request). See "Forms" section above.
+* `formData` - Data to pass for a `multipart/form-data` request. See
+  [Forms](#forms) section above.
+* `multipart` - array of objects which contain their own headers and `body`
+  attributes. Sends a `multipart/related` request. See [Forms](#forms) section
+  above.
+  * Alternatively you can pass in an object `{chunked: false, data: []}` where
+    `chunked` is used to specify whether the request is sent in
+    [chunked transfer encoding](https://en.wikipedia.org/wiki/Chunked_transfer_encoding)
+    (the default is `chunked: true`).  In non-chunked requests, data items with
+    body streams are not allowed.
+* `auth` - A hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional).  See documentation above.
+* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header.  Additionally, parses the response body as JSON.
+* `jsonReviver` - a [reviver function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) that will be passed to `JSON.parse()` when parsing a JSON response body.
+* `preambleCRLF` - append a newline/CRLF before the boundary of your `multipart/form-data` request.
+* `postambleCRLF` - append a newline/CRLF at the end of the boundary of your `multipart/form-data` request.
+* `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`). This property can also be implemented as function which gets `response` object as a single argument and should return `true` if redirects should continue or `false` otherwise.
+* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)
+* `maxRedirects` - the maximum number of redirects to follow (default: `10`)
+* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`. Anything else **(including the default value of `undefined`)** will be passed as the [encoding](http://nodejs.org/api/buffer.html#buffer_buffer) parameter to `toString()` (meaning this is effectively `utf8` by default).
+* `pool` - An object describing which agents to use for the request. If this option is omitted the request will use the global agent (as long as [your options allow for it](request.js#L747)). Otherwise, request will search the pool for your custom agent. If no custom agent is found, a new agent will be created and added to the pool.
+  * A `maxSockets` property can also be provided on the `pool` object to set the max number of sockets for all agents created (ex: `pool: {maxSockets: Infinity}`).
+  * Note that if you are sending multiple requests in a loop and creating
+    multiple new `pool` objects, `maxSockets` will not work as intended.  To
+    work around this, either use [`request.defaults`](#requestdefaultsoptions)
+    with your pool options or create the pool object with the `maxSockets`
+    property outside of the loop.
+* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request
+* `proxy` - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)
+* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above.
+* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).
+* `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
+* `agentOptions` - Object containing user agent options. See documentation above. **Note:** [see tls API doc for TLS/SSL options](http://nodejs.org/api/tls.html#tls_tls_connect_options_callback).
+
+* `jar` - If `true` and `tough-cookie` is installed, remember cookies for future use (or define your custom cookie jar; see examples section)
+* `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services)
+* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.
+* `localAddress` - Local interface to bind for network connections.
+* `gzip` - If `true`, add an `Accept-Encoding` header to request compressed content encodings from the server (if not already present) and decode supported content encodings in the response.  **Note:** Automatic decoding of the response content is performed on the body data returned through `request` (both through the `request` stream and passed to the callback function) but is not performed on the `response` stream (available from the `response` event) which is the unmodified `http.IncomingMessage` object which may contain compressed data. See example below.
+* `tunnel` - If `true`, then *always* use a tunneling proxy.  If
+  `false` (default), then tunneling will only be used if the
+  destination is `https`, or if a previous request in the redirect
+  chain used a tunneling proxy.
+* `proxyHeaderWhiteList` - A whitelist of headers to send to a
+  tunneling proxy.
+* `proxyHeaderExclusiveList` - A whitelist of headers to send
+  exclusively to a tunneling proxy and not to destination.
+
+
+The callback argument gets 3 arguments:
+
+1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)
+2. An [`http.IncomingMessage`](http://nodejs.org/api/http.html#http_http_incomingmessage) object
+3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)
+
+## Convenience methods
+
+There are also shorthand methods for different HTTP METHODs and some other conveniences.
+
+### request.defaults(options)
+
+This method **returns a wrapper** around the normal request API that defaults
+to whatever options you pass to it.
+
+**Note:** `request.defaults()` **does not** modify the global request API;
+instead, it **returns a wrapper** that has your default settings applied to it.
+
+**Note:** You can call `.defaults()` on the wrapper that is returned from
+`request.defaults` to add/override defaults that were previously defaulted.
+
+For example:
+```javascript
+//requests using baseRequest() will set the 'x-token' header
+var baseRequest = request.defaults({
+  headers: {x-token: 'my-token'}
+})
+
+//requests using specialRequest() will include the 'x-token' header set in
+//baseRequest and will also include the 'special' header
+var specialRequest = baseRequest.defaults({
+  headers: {special: 'special value'}
+})
+```
+
+### request.put
+
+Same as `request()`, but defaults to `method: "PUT"`.
+
+```javascript
+request.put(url)
+```
+
+### request.patch
+
+Same as `request()`, but defaults to `method: "PATCH"`.
+
+```javascript
+request.patch(url)
+```
+
+### request.post
+
+Same as `request()`, but defaults to `method: "POST"`.
+
+```javascript
+request.post(url)
+```
+
+### request.head
+
+Same as request() but defaults to `method: "HEAD"`.
+
+```javascript
+request.head(url)
+```
+
+### request.del
+
+Same as `request()`, but defaults to `method: "DELETE"`.
+
+```javascript
+request.del(url)
+```
+
+### request.get
+
+Same as `request()` (for uniformity).
+
+```javascript
+request.get(url)
+```
+### request.cookie
+
+Function that creates a new cookie.
+
+```javascript
+request.cookie('key1=value1')
+```
+### request.jar()
+
+Function that creates a new cookie jar.
+
+```javascript
+request.jar()
+```
+
+
+## Examples:
+
+```javascript
+  var request = require('request')
+    , rand = Math.floor(Math.random()*100000000).toString()
+    ;
+  request(
+    { method: 'PUT'
+    , uri: 'http://mikeal.iriscouch.com/testjs/' + rand
+    , multipart:
+      [ { 'content-type': 'application/json'
+        ,  body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
+        }
+      , { body: 'I am an attachment' }
+      ]
+    }
+  , function (error, response, body) {
+      if(response.statusCode == 201){
+        console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)
+      } else {
+        console.log('error: '+ response.statusCode)
+        console.log(body)
+      }
+    }
+  )
+```
+
+For backwards-compatibility, response compression is not supported by default.
+To accept gzip-compressed responses, set the `gzip` option to `true`.  Note
+that the body data passed through `request` is automatically decompressed
+while the response object is unmodified and will contain compressed data if
+the server sent a compressed response.
+
+```javascript
+  var request = require('request')
+  request(
+    { method: 'GET'
+    , uri: 'http://www.google.com'
+    , gzip: true
+    }
+  , function (error, response, body) {
+      // body is the decompressed response body
+      console.log('server encoded the data as: ' + (response.headers['content-encoding'] || 'identity'))
+      console.log('the decoded data is: ' + body)
+    }
+  ).on('data', function(data) {
+    // decompressed data as it is received
+    console.log('decoded chunk: ' + data)
+  })
+  .on('response', function(response) {
+    // unmodified http.IncomingMessage object
+    response.on('data', function(data) {
+      // compressed data as it is received
+      console.log('received ' + data.length + ' bytes of compressed data')
+    })
+  })
+```
+
+Cookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`) and install `tough-cookie`.
+
+```javascript
+var request = request.defaults({jar: true})
+request('http://www.google.com', function () {
+  request('http://images.google.com')
+})
+```
+
+To use a custom cookie jar (instead of `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)
+
+```javascript
+var j = request.jar()
+var request = request.defaults({jar:j})
+request('http://www.google.com', function () {
+  request('http://images.google.com')
+})
+```
+
+OR
+
+```javascript
+var j = request.jar();
+var cookie = request.cookie('key1=value1');
+var url = 'http://www.google.com';
+j.setCookie(cookie, url);
+request({url: url, jar: j}, function () {
+  request('http://images.google.com')
+})
+```
+
+To use a custom cookie store (such as a
+[`FileCookieStore`](https://github.com/mitsuru/tough-cookie-filestore)
+which supports saving to and restoring from JSON files), pass it as a parameter
+to `request.jar()`:
+
+```javascript
+var FileCookieStore = require('tough-cookie-filestore');
+// NOTE - currently the 'cookies.json' file must already exist!
+var j = request.jar(new FileCookieStore('cookies.json'));
+request = request.defaults({ jar : j })
+request('http://www.google.com', function() {
+  request('http://images.google.com')
+})
+```
+
+The cookie store must be a
+[`tough-cookie`](https://github.com/goinstant/tough-cookie)
+store and it must support synchronous operations; see the
+[`CookieStore` API docs](https://github.com/goinstant/tough-cookie/#cookiestore-api)
+for details.
+
+To inspect your cookie jar after a request:
+
+```javascript
+var j = request.jar()
+request({url: 'http://www.google.com', jar: j}, function () {
+  var cookie_string = j.getCookieString(uri); // "key1=value1; key2=value2; ..."
+  var cookies = j.getCookies(uri);
+  // [{key: 'key1', value: 'value1', domain: "www.google.com", ...}, ...]
+})
+```
+
+## Debugging
+
+There are at least three ways to debug the operation of `request`:
+
+1. Launch the node process like `NODE_DEBUG=request node script.js`
+   (`lib,request,otherlib` works too).
+
+2. Set `require('request').debug = true` at any time (this does the same thing
+   as #1).
+
+3. Use the [request-debug module](https://github.com/nylen/request-debug) to
+   view request and response headers and bodies.

+# bl *(BufferList)*
+
+**A Node.js Buffer list collector, reader and streamer thingy.**
+
+[![NPM](https://nodei.co/npm/bl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/bl/)
+[![NPM](https://nodei.co/npm-dl/bl.png?months=6&height=3)](https://nodei.co/npm/bl/)
+
+**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
+
+The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
+
+```js
+const BufferList = require('bl')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append('hi')                     // bl will also accept & convert Strings
+bl.append(new Buffer('j'))
+bl.append(new Buffer([ 0x3, 0x4 ]))
+
+console.log(bl.length) // 12
+
+console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
+console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
+console.log(bl.slice(3, 6).toString('ascii'))  // 'def'
+console.log(bl.slice(3, 8).toString('ascii'))  // 'defgh'
+console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
+
+// or just use toString!
+console.log(bl.toString())               // 'abcdefghij\u0003\u0004'
+console.log(bl.toString('ascii', 3, 8))  // 'defgh'
+console.log(bl.toString('ascii', 5, 10)) // 'fghij'
+
+// other standard Buffer readables
+console.log(bl.readUInt16BE(10)) // 0x0304
+console.log(bl.readUInt16LE(10)) // 0x0403
+```
+
+Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
+
+```js
+const bl = require('bl')
+    , fs = require('fs')
+
+fs.createReadStream('README.md')
+  .pipe(bl(function (err, data) { // note 'new' isn't strictly required
+    // `data` is a complete Buffer object containing the full data
+    console.log(data.toString())
+  }))
+```
+
+Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
+
+Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
+```js
+const hyperquest = require('hyperquest')
+    , bl         = require('bl')
+    , url        = 'https://raw.github.com/rvagg/bl/master/README.md'
+
+hyperquest(url).pipe(bl(function (err, data) {
+  console.log(data.toString())
+}))
+```
+
+Or, use it as a readable stream to recompose a list of Buffers to an output source:
+
+```js
+const BufferList = require('bl')
+    , fs         = require('fs')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append(new Buffer('hi'))
+bl.append(new Buffer('j'))
+
+bl.pipe(fs.createWriteStream('gibberish.txt'))
+```

+### new BufferList([ callback | buffer | buffer array ])
+The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
+
+Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
+
+`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
+
+```js
+var bl = require('bl')
+var myinstance = bl()
+
+// equivilant to:
+
+var BufferList = require('bl')
+var myinstance = new BufferList()
+```
+
+--------------------------------------------------------
+<a name="length"></a>
+### bl.length
+Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
+
+--------------------------------------------------------
+<a name="append"></a>
+### bl.append(buffer)
+`append(buffer)` adds an additional buffer or BufferList to the internal list.
+
+--------------------------------------------------------
+<a name="get"></a>
+### bl.get(index)
+`get()` will return the byte at the specified index.
+
+--------------------------------------------------------
+<a name="slice"></a>
+### bl.slice([ start, [ end ] ])
+`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
+
+If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
+
+--------------------------------------------------------
+<a name="copy"></a>
+### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
+`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
+
+--------------------------------------------------------
+<a name="duplicate"></a>
+### bl.duplicate()
+`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
+
+```js
+var bl = new BufferList()
+
+bl.append('hello')
+bl.append(' world')
+bl.append('\n')
+
+bl.duplicate().pipe(process.stdout, { end: false })
+
+console.log(bl.toString())
+```
+
+--------------------------------------------------------
+<a name="consume"></a>
+### bl.consume(bytes)
+`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
+
+--------------------------------------------------------
+<a name="toString"></a>
+### bl.toString([encoding, [ start, [ end ]]])
+`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
+
+--------------------------------------------------------
+<a name="readXX"></a>
+### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
+
+All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
+
+See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
+
+--------------------------------------------------------
+<a name="streams"></a>
+### Streams
+**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance.

+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

Alternative\nimplementation is a literal copy of standard one located in standalone\nmodule to avoid requiring of `util`. It also has a shim for old\nbrowsers with no `Object.create` support.\n\nWhile keeping you sure you are using standard `inherits`\nimplementation in node.js environment, it allows bundlers such as\n[browserify](https://github.com/substack/node-browserify) to not\ninclude full `util` package to your client code if all you need is\njust `inherits` function. It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n  superclass\n* new version overwrites current prototype while old one preserves any\n  existing fields on it\n",

+## Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.
+
+This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.
+
+## Usage
+
+```javascript
+var headers = {}
+  , c = caseless(headers)
+  ;
+c.set('a-Header', 'asdf')
+c.get('a-header') === 'asdf'
+```
+
+## has(key)
+
+Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.
+
+```javascript
+c.has('a-header') === 'a-Header'
+```
+
+## set(key, value[, clobber=true])
+
+Set is fairly straight forward except that if the header exists and clobber is disabled it will add `','+value` to the existing header.
+
+```javascript
+c.set('a-Header', 'fdas')
+c.set('a-HEADER', 'more', false)
+c.get('a-header') === 'fdsa,more'
+```
+
+## swap(key)
+
+Swaps the casing of a header with the new one that is passed in.
+
+```javascript
+var headers = {}
+  , c = caseless(headers)
+  ;
+c.set('a-Header', 'fdas')
+c.swap('a-HEADER')
+c.has('a-header') === 'a-HEADER'
+headers === {'a-HEADER': 'fdas'}
+```

+# combined-stream [![Build Status](https://travis-ci.org/felixge/node-combined-stream.svg?branch=master)](https://travis-ci.org/felixge/node-combined-stream)
+
+A stream that emits multiple other streams one after another.
+
+## Installation
+
+``` bash
+npm install combined-stream
+```
+
+## Usage
+
+Here is a simple example that shows how you can use combined-stream to combine
+two files into one:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+While the example above works great, it will pause all source streams until
+they are needed. If you don't want that to happen, you can set `pauseStreams`
+to `false`:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create({pauseStreams: false});
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+However, what if you don't have all the source streams yet, or you don't want
+to allocate the resources (file descriptors, memory, etc.) for them right away?
+Well, in that case you can simply provide a callback that supplies the stream
+by calling a `next()` function:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file1.txt'));
+});
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file2.txt'));
+});
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+## API
+
+### CombinedStream.create([options])
+
+Returns a new combined stream object. Available options are:
+
+* `maxDataSize`
+* `pauseStreams`
+
+The effect of those options is described below.
+
+### combinedStream.pauseStreams = `true`
+
+Whether to apply back pressure to the underlaying streams. If set to `false`,
+the underlaying streams will never be paused. If set to `true`, the
+underlaying streams will be paused right after being appended, as well as when
+`delayedStream.pipe()` wants to throttle.
+
+### combinedStream.maxDataSize = `2 * 1024 * 1024`
+
+The maximum amount of bytes (or characters) to buffer for all source streams.
+If this value is exceeded, `combinedStream` emits an `'error'` event.
+
+### combinedStream.dataSize = `0`
+
+The amount of bytes (or characters) currently buffered by `combinedStream`.
+
+### combinedStream.append(stream)
+
+Appends the given `stream` to the combinedStream object. If `pauseStreams` is
+set to `true, this stream will also be paused right away.
+
+`streams` can also be a function that takes one parameter called `next`. `next`
+is a function that must be invoked in order to provide the `next` stream, see
+example above.
+
+Regardless of how the `stream` is appended, combined-stream always attaches an
+`'error'` listener to it, so you don't have to do that manually.
+
+Special case: `stream` can also be a String or Buffer.
+
+### combinedStream.write(data)
+
+You should not call this, `combinedStream` takes care of piping the appended
+streams into itself for you.
+
+### combinedStream.resume()
+
+Causes `combinedStream` to start drain the streams it manages. The function is
+idempotent, and also emits a `'resume'` event each time which usually goes to
+the stream that is currently being drained.
+
+### combinedStream.pause();
+
+If `combinedStream.pauseStreams` is set to `false`, this does nothing.
+Otherwise a `'pause'` event is emitted, this goes to the stream that is
+currently being drained, so you can use it to apply back pressure.
+
+### combinedStream.end();
+
+Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
+all streams from the queue.
+
+### combinedStream.destroy();
+
+Same as `combinedStream.end()`, except it emits a `'close'` event instead of
+`'end'`.

+# delayed-stream
+
+Buffers events from a stream until you are ready to handle them.
+
+## Installation
+
+``` bash
+npm install delayed-stream
+```
+
+## Usage
+
+The following example shows how to write a http echo server that delays its
+response by 1000 ms.
+
+``` javascript
+var DelayedStream = require('delayed-stream');
+var http = require('http');
+
+http.createServer(function(req, res) {
+  var delayed = DelayedStream.create(req);
+
+  setTimeout(function() {
+    res.writeHead(200);
+    delayed.pipe(res);
+  }, 1000);
+});
+```
+
+If you are not using `Stream#pipe`, you can also manually release the buffered
+events by calling `delayedStream.resume()`:
+
+``` javascript
+var delayed = DelayedStream.create(req);
+
+setTimeout(function() {
+  // Emit all buffered events and resume underlaying source
+  delayed.resume();
+}, 1000);
+```
+
+## Implementation
+
+In order to use this meta stream properly, here are a few things you should
+know about the implementation.
+
+### Event Buffering / Proxying
+
+All events of the `source` stream are hijacked by overwriting the `source.emit`
+method. Until node implements a catch-all event listener, this is the only way.
+
+However, delayed-stream still continues to emit all events it captures on the
+`source`, regardless of whether you have released the delayed stream yet or
+not.
+
+Upon creation, delayed-stream captures all `source` events and stores them in
+an internal event buffer. Once `delayedStream.release()` is called, all
+buffered events are emitted on the `delayedStream`, and the event buffer is
+cleared. After that, delayed-stream merely acts as a proxy for the underlaying
+source.
+
+### Error handling
+
+Error events on `source` are buffered / proxied just like any other events.
+However, `delayedStream.create` attaches a no-op `'error'` listener to the
+`source`. This way you only have to handle errors on the `delayedStream`
+object, rather than in two places.
+
+### Buffer limits
+
+delayed-stream provides a `maxDataSize` property that can be used to limit
+the amount of data being buffered. In order to protect you from bad `source`
+streams that don't react to `source.pause()`, this feature is enabled by
+default.
+
+## API
+
+### DelayedStream.create(source, [options])
+
+Returns a new `delayedStream`. Available options are:
+
+* `pauseStream`
+* `maxDataSize`
+
+The description for those properties can be found below.
+
+### delayedStream.source
+
+The `source` stream managed by this object. This is useful if you are
+passing your `delayedStream` around, and you still want to access properties
+on the `source` object.
+
+### delayedStream.pauseStream = true
+
+Whether to pause the underlaying `source` when calling
+`DelayedStream.create()`. Modifying this property afterwards has no effect.
+
+### delayedStream.maxDataSize = 1024 * 1024
+
+The amount of data to buffer before emitting an `error`.
+
+If the underlaying source is emitting `Buffer` objects, the `maxDataSize`
+refers to bytes.
+
+If the underlaying source is emitting JavaScript strings, the size refers to
+characters.
+
+If you know what you are doing, you can set this property to `Infinity` to
+disable this feature. You can also modify this property during runtime.
+
+### delayedStream.maxDataSize = 1024 * 1024
+
+The amount of data to buffer before emitting an `error`.
+
+If the underlaying source is emitting `Buffer` objects, the `maxDataSize`
+refers to bytes.
+
+If the underlaying source is emitting JavaScript strings, the size refers to
+characters.
+
+If you know what you are doing, you can set this property to `Infinity` to
+disable this feature.
+
+### delayedStream.dataSize = 0
+
+The amount of data buffered so far.
+
+### delayedStream.readable
+
+An ECMA5 getter that returns the value of `source.readable`.
+
+### delayedStream.resume()
+
+If the `delayedStream` has not been released so far, `delayedStream.release()`
+is called.
+
+In either case, `source.resume()` is called.
+
+### delayedStream.pause()
+
+Calls `source.pause()`.
+
+### delayedStream.pipe(dest)
+
+Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`.
+
+### delayedStream.release()
+
+Emits and clears all events that have been buffered up so far. This does not
+resume the underlaying source, use `delayedStream.resume()` instead.

+# mime-types
+
+[![NPM Version][npm-image]][npm-url]
+[![NPM Downloads][downloads-image]][downloads-url]
+[![Node.js Version][node-version-image]][node-version-url]
+[![Build Status][travis-image]][travis-url]
+[![Test Coverage][coveralls-image]][coveralls-url]
+
+The ultimate javascript content-type utility.
+
+Similar to [node-mime](https://github.com/broofa/node-mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type, `mime-types` simply returns `false`,
+  so do `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- Additional mime types are added such as jade and stylus via [mime-db](https://github.com/jshttp/mime-db)
+- No `.define()` functionality
+
+Otherwise, the API is compatible.
+
+## Install
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://github.com/jshttp/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json')           // 'application/json'
+mime.lookup('.md')            // 'text/x-markdown'
+mime.lookup('file.html')      // 'text/html'
+mime.lookup('folder/file.js') // 'application/javascript'
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+
+```js
+mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/x-markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]

+
+This is a database of all mime types.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+If you're crazy enough to use this in the browser,
+you can just grab the JSON file:
+
+```
+https://cdn.rawgit.com/jshttp/mime-db/master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db');
+
+// grab data on .js files
+var data = db['application/javascript'];
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type is can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom.json` or
+`src/custom-suffix.json`.
+
+To update the build, run `npm run update`.
+
+## Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.

+# Introduction
+
+**Hawk** is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with
+partial cryptographic verification of the request and response, covering the HTTP method, request URI, host,
+and optionally the request payload.
+
+Similar to the HTTP [Digest access authentication schemes](http://www.ietf.org/rfc/rfc2617.txt), **Hawk** uses a set of
+client credentials which include an identifier (e.g. username) and key (e.g. password). Likewise, just as with the Digest scheme,
+the key is never included in authenticated requests. Instead, it is used to calculate a request MAC value which is
+included in its place.
+
+However, **Hawk** has several differences from Digest. In particular, while both use a nonce to limit the possibility of
+replay attacks, in **Hawk** the client generates the nonce and uses it in combination with a timestamp, leading to less
+"chattiness" (interaction with the server).
+
+Also unlike Digest, this scheme is not intended to protect the key itself (the password in Digest) because
+the client and server must both have access to the key material in the clear.
+
+The primary design goals of this scheme are to:
+* simplify and improve HTTP authentication for services that are unwilling or unable to deploy TLS for all resources,
+* secure credentials against leakage (e.g., when the client uses some form of dynamic configuration to determine where
+  to send an authenticated request), and
+* avoid the exposure of credentials sent to a malicious server over an unauthenticated secure channel due to client
+  failure to validate the server's identity as part of its TLS handshake.
+
+In addition, **Hawk** supports a method for granting third-parties temporary access to individual resources using
+a query parameter called _bewit_ (in falconry, a leather strap used to attach a tracking device to the leg of a hawk).
+
+The **Hawk** scheme requires the establishment of a shared symmetric key between the client and the server,
+which is beyond the scope of this module. Typically, the shared credentials are established via an initial
+TLS-protected phase or derived from some other shared confidential information available to both the client
+and the server.
+
+
+## Replay Protection
+
+Without replay protection, an attacker can use a compromised (but otherwise valid and authenticated) request more 
+than once, gaining access to a protected resource. To mitigate this, clients include both a nonce and a timestamp when 
+making requests. This gives the server enough information to prevent replay attacks.
+
+The nonce is generated by the client, and is a string unique across all requests with the same timestamp and
+key identifier combination. 
+
+The timestamp enables the server to restrict the validity period of the credentials where requests occuring afterwards
+are rejected. It also removes the need for the server to retain an unbounded number of nonce values for future checks.
+By default, **Hawk** uses a time window of 1 minute to allow for time skew between the client and server (which in
+practice translates to a maximum of 2 minutes as the skew can be positive or negative).
+
+Using a timestamp requires the client's clock to be in sync with the server's clock. **Hawk** requires both the client
+clock and the server clock to use NTP to ensure synchronization. However, given the limitations of some client types
+(e.g. browsers) to deploy NTP, the server provides the client with its current time (in seconds precision) in response
+to a bad timestamp.
+
+There is no expectation that the client will adjust its system clock to match the server (in fact, this would be a
+potential attack vector). Instead, the client only uses the server's time to calculate an offset used only
+for communications with that particular server. The protocol rewards clients with synchronized clocks by reducing
+the number of round trips required to authenticate the first request.
+
+
+## Usage Example
+
+Server code:
+
+```javascript
+var Http = require('http');
+var Hawk = require('hawk');
+
+
+// Credentials lookup function
+
+var credentialsFunc = function (id, callback) {
+
+    var credentials = {
+        key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn',
+        algorithm: 'sha256',
+        user: 'Steve'
+    };
+
+    return callback(null, credentials);
+};
+
+// Create HTTP server
+
+var handler = function (req, res) {
+
+    // Authenticate incoming request
+
+    Hawk.server.authenticate(req, credentialsFunc, {}, function (err, credentials, artifacts) {
+
+        // Prepare response
+
+        var payload = (!err ? 'Hello ' + credentials.user + ' ' + artifacts.ext : 'Shoosh!');
+        var headers = { 'Content-Type': 'text/plain' };
+
+        // Generate Server-Authorization response header
+
+        var header = Hawk.server.header(credentials, artifacts, { payload: payload, contentType: headers['Content-Type'] });
+        headers['Server-Authorization'] = header;
+
+        // Send the response back
+
+        res.writeHead(!err ? 200 : 401, headers);
+        res.end(payload);
+    });
+};
+
+// Start server
+
+Http.createServer(handler).listen(8000, 'example.com');
+```
+
+Client code:
+
+```javascript
+var Request = require('request');
+var Hawk = require('hawk');
+
+
+// Client credentials
+
+var credentials = {
+    id: 'dh37fgj492je',
+    key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn',
+    algorithm: 'sha256'
+}
+
+// Request options
+
+var requestOptions = {
+    uri: 'http://example.com:8000/resource/1?b=1&a=2',
+    method: 'GET',
+    headers: {}
+};
+
+// Generate Authorization request header
+
+var header = Hawk.client.header('http://example.com:8000/resource/1?b=1&a=2', 'GET', { credentials: credentials, ext: 'some-app-data' });
+requestOptions.headers.Authorization = header.field;
+
+// Send authenticated request
+
+Request(requestOptions, function (error, response, body) {
+
+    // Authenticate the server's response
+
+    var isValid = Hawk.client.authenticate(response, credentials, header.artifacts, { payload: body });
+
+    // Output results
+
+    console.log(response.statusCode + ': ' + body + (isValid ? ' (valid)' : ' (invalid)'));
+});
+```
+
+**Hawk** utilized the [**SNTP**](https://github.com/hueniverse/sntp) module for time sync management. By default, the local
+machine time is used. To automatically retrieve and synchronice the clock within the application, use the SNTP 'start()' method.
+
+```javascript
+Hawk.sntp.start();
+```
+
+
+## Protocol Example
+
+The client attempts to access a protected resource without authentication, sending the following HTTP request to
+the resource server:
+
+```
+GET /resource/1?b=1&a=2 HTTP/1.1
+Host: example.com:8000
+```
+
+The resource server returns an authentication challenge.
+
+```
+HTTP/1.1 401 Unauthorized
+WWW-Authenticate: Hawk
+```
+
+The client has previously obtained a set of **Hawk** credentials for accessing resources on the "http://example.com/"
+server. The **Hawk** credentials issued to the client include the following attributes:
+
+* Key identifier: dh37fgj492je
+* Key: werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn
+* Algorithm: sha256
+
+The client generates the authentication header by calculating a timestamp (e.g. the number of seconds since January 1,
+1970 00:00:00 GMT), generating a nonce, and constructing the normalized request string (each value followed by a newline
+character):
+
+```
+hawk.1.header
+1353832234
+j4h3g2
+GET
+/resource/1?b=1&a=2
+example.com
+8000
+
+some-app-ext-data
+
+```
+
+The request MAC is calculated using HMAC with the specified hash algorithm "sha256" and the key over the normalized request string.
+The result is base64-encoded to produce the request MAC:
+
+```
+6R4rV5iE+NPoym+WwjeHzjAGXUtLNIxmo1vpMofpLAE=
+```
+
+The client includes the **Hawk** key identifier, timestamp, nonce, application specific data, and request MAC with the request using
+the HTTP `Authorization` request header field:
+
+```
+GET /resource/1?b=1&a=2 HTTP/1.1
+Host: example.com:8000
+Authorization: Hawk id="dh37fgj492je", ts="1353832234", nonce="j4h3g2", ext="some-app-ext-data", mac="6R4rV5iE+NPoym+WwjeHzjAGXUtLNIxmo1vpMofpLAE="
+```
+
+The server validates the request by calculating the request MAC again based on the request received and verifies the validity
+and scope of the **Hawk** credentials. If valid, the server responds with the requested resource.
+
+
+### Payload Validation
+
+**Hawk** provides optional payload validation. When generating the authentication header, the client calculates a payload hash
+using the specified hash algorithm. The hash is calculated over the concatenated value of (each followed by a newline character):
+* `hawk.1.payload`
+* the content-type in lowercase, without any parameters (e.g. `application/json`)
+* the request payload prior to any content encoding (the exact representation requirements should be specified by the server for payloads other than simple single-part ascii to ensure interoperability)
+
+For example:
+
+* Payload: `Thank you for flying Hawk`
+* Content Type: `text/plain`
+* Hash (sha256): `Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY=`
+
+Results in the following input to the payload hash function (newline terminated values):
+
+```
+hawk.1.payload
+text/plain
+Thank you for flying Hawk
+
+```
+
+Which produces the following hash value:
+
+```
+Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY=
+```
+
+The client constructs the normalized request string (newline terminated values):
+
+```
+hawk.1.header

+
+```
+
+Then calculates the request MAC and includes the **Hawk** key identifier, timestamp, nonce, payload hash, application specific data,
+and request MAC, with the request using the HTTP `Authorization` request header field:
+
+```
+POST /resource/1?a=1&b=2 HTTP/1.1
+Host: example.com:8000
+Authorization: Hawk id="dh37fgj492je", ts="1353832234", nonce="j4h3g2", hash="Yi9LfIIFRtBEPt74PVmbTF/xVAwPn7ub15ePICfgnuY=", ext="some-app-ext-data", mac="aSe1DERmZuRl3pI36/9BdZmnErTw3sNzOOAUlfeKjVw="
+```
+
+It is up to the server if and when it validates the payload for any given request, based solely on it's security policy
+and the nature of the data included.
+
+If the payload is available at the time of authentication, the server uses the hash value provided by the client to construct
+the normalized string and validates the MAC. If the MAC is valid, the server calculates the payload hash and compares the value
+with the provided payload hash in the header. In many cases, checking the MAC first is faster than calculating the payload hash.
+
+However, if the payload is not available at authentication time (e.g. too large to fit in memory, streamed elsewhere, or processed
+at a different stage in the application), the server may choose to defer payload validation for later by retaining the hash value
+provided by the client after validating the MAC.
+
+It is important to note that MAC validation does not mean the hash value provided by the client is valid, only that the value
+included in the header was not modified. Without calculating the payload hash on the server and comparing it to the value provided
+by the client, the payload may be modified by an attacker.
+
+
+## Response Payload Validation
+
+**Hawk** provides partial response payload validation. The server includes the `Server-Authorization` response header which enables the
+client to authenticate the response and ensure it is talking to the right server. **Hawk** defines the HTTP `Server-Authorization` header
+as a response header using the exact same syntax as the `Authorization` request header field.
+
+The header is contructed using the same process as the client's request header. The server uses the same credentials and other
+artifacts provided by the client to constructs the normalized request string. The `ext` and `hash` values are replaced with
+new values based on the server response. The rest as identical to those used by the client.
+
+The result MAC digest is included with the optional `hash` and `ext` values:
+
+```
+Server-Authorization: Hawk mac="XIJRsMl/4oL+nn+vKoeVZPdCHXB4yJkNnBbTbHFZUYE=", hash="f9cDF/TDm7TkYRLnGwRMfeDzT6LixQVLvrIKhh0vgmM=", ext="response-specific"
+```
+
+
+## Browser Support and Considerations
+
+A browser script is provided for including using a `<script>` tag in [lib/browser.js](/lib/browser.js).
+
+**Hawk** relies on the _Server-Authorization_ and _WWW-Authenticate_ headers in its response to communicate with the client.
+Therefore, in case of CORS requests, it is important to consider sending _Access-Control-Expose-Headers_ with the value
+_"WWW-Authenticate, Server-Authorization"_ on each response from your server. As explained in the
+[specifications](http://www.w3.org/TR/cors/#access-control-expose-headers-response-header), it will indicate that these headers
+can safely be accessed by the client (using getResponseHeader() on the XmlHttpRequest object). Otherwise you will be met with a
+["simple response header"](http://www.w3.org/TR/cors/#simple-response-header) which excludes these fields and would prevent the
+Hawk client from authenticating the requests.You can read more about the why and how in this
+[article](http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server)
+
+
+# Single URI Authorization
+
+There are cases in which limited and short-term access to a protected resource is granted to a third party which does not
+have access to the shared credentials. For example, displaying a protected image on a web page accessed by anyone. **Hawk**
+provides limited support for such URIs in the form of a _bewit_ - a URI query parameter appended to the request URI which contains
+the necessary credentials to authenticate the request.
+
+Because of the significant security risks involved in issuing such access, bewit usage is purposely limited only to GET requests
+and for a finite period of time. Both the client and server can issue bewit credentials, however, the server should not use the same
+credentials as the client to maintain clear traceability as to who issued which credentials.
+
+In order to simplify implementation, bewit credentials do not support single-use policy and can be replayed multiple times within
+the granted access timeframe. 
+
+
+## Bewit Usage Example
+
+Server code:
+
+```javascript
+var Http = require('http');
+var Hawk = require('hawk');
+
+
+// Credentials lookup function
+
+var credentialsFunc = function (id, callback) {
+
+    var credentials = {
+        key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn',
+        algorithm: 'sha256'
+    };
+
+    return callback(null, credentials);
+};
+
+// Create HTTP server
+
+var handler = function (req, res) {
+
+    Hawk.uri.authenticate(req, credentialsFunc, {}, function (err, credentials, attributes) {
+
+        res.writeHead(!err ? 200 : 401, { 'Content-Type': 'text/plain' });
+        res.end(!err ? 'Access granted' : 'Shoosh!');
+    });
+};
+
+Http.createServer(handler).listen(8000, 'example.com');
+```
+
+Bewit code generation:
+
+```javascript
+var Request = require('request');
+var Hawk = require('hawk');
+
+
+// Client credentials
+
+var credentials = {
+    id: 'dh37fgj492je',
+    key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn',
+    algorithm: 'sha256'
+}
+
+// Generate bewit
+
+var duration = 60 * 5;      // 5 Minutes
+var bewit = Hawk.uri.getBewit('http://example.com:8080/resource/1?b=1&a=2', { credentials: credentials, ttlSec: duration, ext: 'some-app-data' });
+var uri = 'http://example.com:8000/resource/1?b=1&a=2' + '&bewit=' + bewit;
+```
+
+
+# Security Considerations
+
+The greatest sources of security risks are usually found not in **Hawk** but in the policies and procedures surrounding its use.
+Implementers are strongly encouraged to assess how this module addresses their security requirements. This section includes
+an incomplete list of security considerations that must be reviewed and understood before deploying **Hawk** on the server.
+Many of the protections provided in **Hawk** depends on whether and how they are used.
+
+### MAC Keys Transmission
+
+**Hawk** does not provide any mechanism for obtaining or transmitting the set of shared credentials required. Any mechanism used
+to obtain **Hawk** credentials must ensure that these transmissions are protected using transport-layer mechanisms such as TLS.
+
+### Confidentiality of Requests
+
+While **Hawk** provides a mechanism for verifying the integrity of HTTP requests, it provides no guarantee of request
+confidentiality. Unless other precautions are taken, eavesdroppers will have full access to the request content. Servers should
+carefully consider the types of data likely to be sent as part of such requests, and employ transport-layer security mechanisms
+to protect sensitive resources.
+
+### Spoofing by Counterfeit Servers
+
+**Hawk** provides limited verification of the server authenticity. When receiving a response back from the server, the server
+may choose to include a response `Server-Authorization` header which the client can use to verify the response. However, it is up to
+the server to determine when such measure is included, to up to the client to enforce that policy.
+
+A hostile party could take advantage of this by intercepting the client's requests and returning misleading or otherwise
+incorrect responses. Service providers should consider such attacks when developing services using this protocol, and should
+require transport-layer security for any requests where the authenticity of the resource server or of server responses is an issue.
+
+### Plaintext Storage of Credentials
+
+The **Hawk** key functions the same way passwords do in traditional authentication systems. In order to compute the request MAC,
+the server must have access to the key in plaintext form. This is in contrast, for example, to modern operating systems, which
+store only a one-way hash of user credentials.
+
+If an attacker were to gain access to these keys - or worse, to the server's database of all such keys - he or she would be able
+to perform any action on behalf of any resource owner. Accordingly, it is critical that servers protect these keys from unauthorized
+access.
+
+### Entropy of Keys
+
+Unless a transport-layer security protocol is used, eavesdroppers will have full access to authenticated requests and request
+MAC values, and will thus be able to mount offline brute-force attacks to recover the key used. Servers should be careful to
+assign keys which are long enough, and random enough, to resist such attacks for at least the length of time that the **Hawk**
+credentials are valid.
+
+For example, if the credentials are valid for two weeks, servers should ensure that it is not possible to mount a brute force
+attack that recovers the key in less than two weeks. Of course, servers are urged to err on the side of caution, and use the
+longest key reasonable.
+
+It is equally important that the pseudo-random number generator (PRNG) used to generate these keys be of sufficiently high
+quality. Many PRNG implementations generate number sequences that may appear to be random, but which nevertheless exhibit
+patterns or other weaknesses which make cryptanalysis or brute force attacks easier. Implementers should be careful to use
+cryptographically secure PRNGs to avoid these problems.
+
+### Coverage Limitations
+
+The request MAC only covers the HTTP `Host` header and optionally the `Content-Type` header. It does not cover any other headers
+which can often affect how the request body is interpreted by the server. If the server behavior is influenced by the presence
+or value of such headers, an attacker can manipulate the request headers without being detected. Implementers should use the
+`ext` feature to pass application-specific information via the `Authorization` header which is protected by the request MAC.
+
+The response authentication, when performed, only covers the response payload, content-type, and the request information 
+provided by the client in it's request (method, resource, timestamp, nonce, etc.). It does not cover the HTTP status code or
+any other response header field (e.g. Location) which can affect the client's behaviour.
+
+### Future Time Manipulation
+
+The protocol relies on a clock sync between the client and server. To accomplish this, the server informs the client of its
+current time when an invalid timestamp is received.
+
+If an attacker is able to manipulate this information and cause the client to use an incorrect time, it would be able to cause
+the client to generate authenticated requests using time in the future. Such requests will fail when sent by the client, and will
+not likely leave a trace on the server (given the common implementation of nonce, if at all enforced). The attacker will then
+be able to replay the request at the correct time without detection.
+
+The client must only use the time information provided by the server if:
+* it was delivered over a TLS connection and the server identity has been verified, or
+* the `tsm` MAC digest calculated using the same client credentials over the timestamp has been verified.
+
+### Client Clock Poisoning
+
+When receiving a request with a bad timestamp, the server provides the client with its current time. The client must never use
+the time received from the server to adjust its own clock, and must only use it to calculate an offset for communicating with
+that particular server.
+
+### Bewit Limitations
+
+Special care must be taken when issuing bewit credentials to third parties. Bewit credentials are valid until expiration and cannot
+be revoked or limited without using other means. Whatever resource they grant access to will be completely exposed to anyone with
+access to the bewit credentials which act as bearer credentials for that particular resource. While bewit usage is limited to GET
+requests only and therefore cannot be used to perform transactions or change server state, it can still be used to expose private
+and sensitive information.
+
+### Host Header Forgery
+
+Hawk validates the incoming request MAC against the incoming HTTP Host header. However, unless the optional `host` and `port`
+options are used with `server.authenticate()`, a malicous client can mint new host names pointing to the server's IP address and
+use that to craft an attack by sending a valid request that's meant for another hostname than the one used by the server. Server
+implementors must manually verify that the host header received matches their expectation (or use the options mentioned above).
+
+# Frequently Asked Questions
+
+### Where is the protocol specification?
+
+If you are looking for some prose explaining how all this works, **this is it**. **Hawk** is being developed as an open source
+project instead of a standard. In other words, the [code](/hueniverse/hawk/tree/master/lib) is the specification. Not sure about
+something? Open an issue!
+
+### Is it done?
+
+At if version 0.10.0, **Hawk** is feature-complete. However, until this module reaches version 1.0.0 it is considered experimental
+and is likely to change. This also means your feedback and contribution are very welcome. Feel free to open issues with questions
+and suggestions.
+
+### Where can I find **Hawk** implementations in other languages?
+
+**Hawk**'s only reference implementation is provided in JavaScript as a node.js module. However, it has been ported to other languages.
+The full list is maintained [here](https://github.com/hueniverse/hawk/issues?labels=port&state=closed). Please add an issue if you are
+working on another port. A cross-platform test-suite is in the works.
+
+### Why isn't the algorithm part of the challenge or dynamically negotiated?
+
+The algorithm used is closely related to the key issued as different algorithms require different key sizes (and other
+requirements). While some keys can be used for multiple algorithm, the protocol is designed to closely bind the key and algorithm
+together as part of the issued credentials.
+
+### Why is Host and Content-Type the only headers covered by the request MAC?
+
+It is really hard to include other headers. Headers can be changed by proxies and other intermediaries and there is no
+well-established way to normalize them. Many platforms change the case of header field names and values. The only
+straight-forward solution is to include the headers in some blob (say, base64 encoded JSON) and include that with the request,
+an approach taken by JWT and other such formats. However, that design violates the HTTP header boundaries, repeats information,
+and introduces other security issues because firewalls will not be aware of these "hidden" headers. In addition, any information
+repeated must be compared to the duplicated information in the header and therefore only moves the problem elsewhere.
+
+### Why not just use HTTP Digest?
+
+Digest requires pre-negotiation to establish a nonce. This means you can't just make a request - you must first send
+a protocol handshake to the server. This pattern has become unacceptable for most web services, especially mobile
+where extra round-trip are costly.
+
+### Why bother with all this nonce and timestamp business?
+
+**Hawk** is an attempt to find a reasonable, practical compromise between security and usability. OAuth 1.0 got timestamp
+and nonces halfway right but failed when it came to scalability and consistent developer experience. **Hawk** addresses
+it by requiring the client to sync its clock, but provides it with tools to accomplish it.
+
+In general, replay protection is a matter of application-specific threat model. It is less of an issue on a TLS-protected
+system where the clients are implemented using best practices and are under the control of the server. Instead of dropping
+replay protection, **Hawk** offers a required time window and an optional nonce verification. Together, it provides developers
+with the ability to decide how to enforce their security policy without impacting the client's implementation.
+
+### What are `app` and `dlg` in the authorization header and normalized mac string?
+
+The original motivation for **Hawk** was to replace the OAuth 1.0 use cases. This included both a simple client-server mode which
+this module is specifically designed for, and a delegated access mode which is being developed separately in
+[Oz](https://github.com/hueniverse/oz). In addition to the **Hawk** use cases, Oz requires another attribute: the application id `app`.
+This provides binding between the credentials and the application in a way that prevents an attacker from tricking an application
+to use credentials issued to someone else. It also has an optional 'delegated-by' attribute `dlg` which is the application id of the
+application the credentials were directly issued to. The goal of these two additions is to allow Oz to utilize **Hawk** directly,
+but with the additional security of delegated credentials.
+
+### What is the purpose of the static strings used in each normalized MAC input?
+
+When calculating a hash or MAC, a static prefix (tag) is added. The prefix is used to prevent MAC values from being
+used or reused for a purpose other than what they were created for (i.e. prevents switching MAC values between a request,
+response, and a bewit use cases). It also protects against expliots created after a potential change in how the protocol
+creates the normalized string. For example, if a future version would switch the order of nonce and timestamp, it
+can create an exploit opportunity for cases where the nonce is similar in format to a timestamp.
+
+### Does **Hawk** have anything to do with OAuth?
+
+Short answer: no.
+
+**Hawk** was originally proposed as the OAuth MAC Token specification. However, the OAuth working group in its consistent
+incompetence failed to produce a final, usable solution to address one of the most popular use cases of OAuth 1.0 - using it
+to authenticate simple client-server transactions (i.e. two-legged). As you can guess, the OAuth working group is still hard
+at work to produce more garbage.
+
+**Hawk** provides a simple HTTP authentication scheme for making client-server requests. It does not address the OAuth use case
+of delegating access to a third party. If you are looking for an OAuth alternative, check out [Oz](https://github.com/hueniverse/oz).

+  
+        payload:               optional payload for validation. The client calculates the hash value and includes it via the 'hash'

+# node-http-signature
+
+node-http-signature is a node.js library that has client and server components
+for Joyent's [HTTP Signature Scheme](http_signing.md).
+
+## Usage
+
+Note the example below signs a request with the same key/cert used to start an
+HTTP server. This is almost certainly not what you actually want, but is just
+used to illustrate the API calls; you will need to provide your own key
+management in addition to this library.
+
+### Client
+
+```js
+var fs = require('fs');
+var https = require('https');
+var httpSignature = require('http-signature');
+
+var key = fs.readFileSync('./key.pem', 'ascii');
+
+var options = {
+  host: 'localhost',
+  port: 8443,
+  path: '/',
+  method: 'GET',
+  headers: {}
+};
+
+// Adds a 'Date' header in, signs it, and adds the
+// 'Authorization' header in.
+var req = https.request(options, function(res) {
+  console.log(res.statusCode);
+});
+
+
+httpSignature.sign(req, {
+  key: key,
+  keyId: './cert.pem'
+});
+
+req.end();
+```
+
+### Server
+
+```js
+var fs = require('fs');
+var https = require('https');
+var httpSignature = require('http-signature');
+
+var options = {
+  key: fs.readFileSync('./key.pem'),
+  cert: fs.readFileSync('./cert.pem')
+};
+
+https.createServer(options, function (req, res) {
+  var rc = 200;
+  var parsed = httpSignature.parseRequest(req);
+  var pub = fs.readFileSync(parsed.keyId, 'ascii');
+  if (!httpSignature.verifySignature(parsed, pub))
+    rc = 401;
+
+  res.writeHead(rc);
+  res.end();
+}).listen(8443);
+```

+# Abstract
+
+This document describes a way to add origin authentication, message integrity,
+and replay resistance to HTTP REST requests.  It is intended to be used over
+the HTTPS protocol.

+
+# Introduction
+
+This protocol is intended to provide a standard way for clients to sign HTTP
+requests.  RFC2617 (HTTP Authentication) defines Basic and Digest authentication
+mechanisms, and RFC5246 (TLS 1.2) defines client-auth, both of which are widely
+employed on the Internet today.  However, it is common place that the burdens of
+PKI prevent web service operators from deploying that methodology, and so many
+fall back to Basic authentication, which has poor security characteristics.
+
+Additionally, OAuth provides a fully-specified alternative for authorization
+of web service requests, but is not (always) ideal for machine to machine
+communication, as the key acquisition steps (generally) imply a fixed
+infrastructure that may not make sense to a service provider (e.g., symmetric
+keys).
+
+Several web service providers have invented their own schemes for signing
+HTTP requests, but to date, none have been placed in the public domain as a
+standard.  This document serves that purpose.  There are no techniques in this
+proposal that are novel beyond previous art, however, this aims to be a simple
+mechanism for signing these requests.
+
+# Signature Authentication Scheme
+
+The "signature" authentication scheme is based on the model that the client must
+authenticate itself with a digital signature produced by either a private
+asymmetric key (e.g., RSA) or a shared symmetric key (e.g., HMAC).  The scheme
+is parameterized enough such that it is not bound to any particular key type or
+signing algorithm.  However, it does explicitly assume that clients can send an
+HTTP `Date` header.
+
+## Authorization Header
+
+The client is expected to send an Authorization header (as defined in RFC 2617)
+with the following parameterization:
+
+    credentials := "Signature" params
+    params := 1#(keyId | algorithm | [headers] | [ext] | signature)
+    digitalSignature := plain-string
+
+    keyId := "keyId" "=" <"> plain-string <">
+    algorithm := "algorithm" "=" <"> plain-string <">
+    headers := "headers" "=" <"> 1#headers-value <">
+    ext := "ext" "=" <"> plain-string <">
+    signature := "signature" "=" <"> plain-string <">
+
+    headers-value := plain-string
+    plain-string   = 1*( %x20-21 / %x23-5B / %x5D-7E )
+
+### Signature Parameters
+
+#### keyId
+
+REQUIRED.  The `keyId` field is an opaque string that the server can use to look
+up the component they need to validate the signature.  It could be an SSH key
+fingerprint, an LDAP DN, etc.  Management of keys and assignment of `keyId` is
+out of scope for this document.
+
+#### algorithm
+
+REQUIRED. The `algorithm` parameter is used if the client and server agree on a
+non-standard digital signature algorithm.  The full list of supported signature
+mechanisms is listed below.
+
+#### headers
+
+OPTIONAL.  The `headers` parameter is used to specify the list of HTTP headers
+used to sign the request.  If specified, it should be a quoted list of HTTP
+header names, separated by a single space character.  By default, only one
+HTTP header is signed, which is the `Date` header.  Note that the list MUST be
+specified in the order the values are concatenated together during signing. To
+include the HTTP request line in the signature calculation, use the special
+`request-line` value.  While this is overloading the definition of `headers` in
+HTTP linguism, the request-line is defined in RFC 2616, and as the outlier from
+headers in useful signature calculation, it is deemed simpler to simply use
+`request-line` than to add a separate parameter for it.
+
+#### extensions
+
+OPTIONAL.  The `extensions` parameter is used to include additional information
+which is covered by the request.  The content and format of the string is out of
+scope for this document, and expected to be specified by implementors.
+
+#### signature
+
+REQUIRED.  The `signature` parameter is a `Base64` encoded digital signature
+generated by the client. The client uses the `algorithm` and `headers` request
+parameters to form a canonicalized `signing string`.  This `signing string` is
+then signed with the key associated with `keyId` and the algorithm
+corresponding to `algorithm`.  The `signature` parameter is then set to the
+`Base64` encoding of the signature.
+
+### Signing String Composition
+
+In order to generate the string that is signed with a key, the client MUST take
+the values of each HTTP header specified by `headers` in the order they appear.
+
+1. If the header name is not `request-line` then append the lowercased header
+   name followed with an ASCII colon `:` and an ASCII space ` `.
+2. If the header name is `request-line` then append the HTTP request line,
+   otherwise append the header value.
+3. If value is not the last value then append an ASCII newline `\n`. The string
+   MUST NOT include a trailing ASCII newline.
+
+# Example Requests
+
+All requests refer to the following request (body omitted):
+
+    POST /foo HTTP/1.1
+    Host: example.org
+    Date: Tue, 07 Jun 2011 20:51:35 GMT
+    Content-Type: application/json
+    Content-MD5: h0auK8hnYJKmHTLhKtMTkQ==
+    Content-Length: 123
+
+The "rsa-key-1" keyId refers to a private key known to the client and a public
+key known to the server. The "hmac-key-1" keyId refers to key known to the
+client and server.
+
+## Default parameterization
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",signature="Base64(RSA-SHA256(signing string))"
+
+The client would compose the signing string as:
+
+    date: Tue, 07 Jun 2011 20:51:35 GMT
+
+## Header List
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",headers="request-line date content-type content-md5",signature="Base64(RSA-SHA256(signing string))"
+
+The client would compose the signing string as (`+ "\n"` inserted for
+readability):
+
+    POST /foo HTTP/1.1 + "\n"
+    date: Tue, 07 Jun 2011 20:51:35 GMT + "\n"
+    content-type: application/json + "\n"
+    content-md5: h0auK8hnYJKmHTLhKtMTkQ==
+
+## Algorithm
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="hmac-key-1",algorithm="hmac-sha1",signature="Base64(HMAC-SHA1(signing string))"
+
+The client would compose the signing string as:
+
+    date: Tue, 07 Jun 2011 20:51:35 GMT
+
+# Signing Algorithms
+
+Currently supported algorithm names are:
+
+* rsa-sha1
+* rsa-sha256
+* rsa-sha512
+* dsa-sha1
+* hmac-sha1
+* hmac-sha256
+* hmac-sha512
+
+# Security Considerations
+
+## Default Parameters
+
+Note the default parameterization of the `Signature` scheme is only safe if all
+requests are carried over a secure transport (i.e., TLS).  Sending the default
+scheme over a non-secure transport will leave the request vulnerable to
+spoofing, tampering, replay/repudiation, and integrity violations (if using the
+STRIDE threat-modeling methodology).
+
+## Insecure Transports
+
+If sending the request over plain HTTP, service providers SHOULD require clients
+to sign ALL HTTP headers, and the `request-line`.  Additionally, service
+providers SHOULD require `Content-MD5` calculations to be performed to ensure
+against any tampering from clients.
+
+## Nonces
+
+Nonces are out of scope for this document simply because many service providers
+fail to implement them correctly, or do not adopt security specifications
+because of the infrastructure complexity.  Given the `header` parameterization,
+a service provider is fully enabled to add nonce semantics into this scheme by
+using something like an `x-request-nonce` header, and ensuring it is signed
+with the `Date` header.
+
+## Clock Skew
+
+As the default scheme is to sign the `Date` header, service providers SHOULD
+protect against logged replay attacks by enforcing a clock skew.  The server
+SHOULD be synchronized with NTP, and the recommendation in this specification
+is to allow 300s of clock skew (in either direction).
+
+## Required Headers to Sign
+
+It is out of scope for this document to dictate what headers a service provider
+will want to enforce, but service providers SHOULD at minimum include the
+`Date` header.

+# mime-types
+[![NPM version](https://badge.fury.io/js/mime-types.svg)](https://badge.fury.io/js/mime-types) [![Build Status](https://travis-ci.org/expressjs/mime-types.svg?branch=master)](https://travis-ci.org/expressjs/mime-types)
+
+The ultimate javascript content-type utility.
+
+### Install
+
+```sh
+$ npm install mime-types
+```
+
+#### Similar to [node-mime](https://github.com/broofa/node-mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type, `mime-types` simply returns `false`, so do `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- Additional mime types are added such as jade and stylus. Feel free to add more!
+- Browser support via Browserify and Component by converting lists to JSON files.
+
+Otherwise, the API is compatible.
+
+### Adding Types
+
+If you'd like to add additional types,
+simply create a PR adding the type to `custom.json` and
+a reference link to the [sources](SOURCES.md).
+
+Do __NOT__ edit `mime.json` or `node.json`.
+Those are pulled using `build.js`.
+You should only touch `custom.json`.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json')           // 'application/json'
+mime.lookup('.md')            // 'text/x-markdown'
+mime.lookup('file.html')      // 'text/html'
+mime.lookup('folder/file.js') // 'application/javascript'
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+
+```js
+mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/x-markdown') // 'UTF-8'
+```
+
+### mime.types[extension] = type
+
+A map of content-types by extension.
+
+### mime.extensions[type] = [extensions]
+
+A map of extensions by content-type.
+
+### mime.define(types)
+
+Globally add definitions.
+`types` must be an object of the form:
+
+```js
+{
+  "<content-type>": [extensions...],
+  "<content-type>": [extensions...]
+}
+```
+
+See the `.json` files in `lib/` for examples.

+
+[Sources for node.json types](https://github.com/broofa/node-mime/blob/master/types/node.types)
+
+### Notes on weird types
+
+- `font/opentype` - This type is technically invalid according to the spec. No valid types begin with `font/`. No-one uses the official type of `application/vnd.ms-opentype` as the community standardized `application/x-font-otf`. However, chrome logs nonsense warnings unless opentype fonts are served with `font/opentype`. [[1]](http://stackoverflow.com/questions/2871655/proper-mime-type-for-fonts)

+# node-uuid
+
+Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.
+
+Features:
+
+* Generate RFC4122 version 1 or version 4 UUIDs
+* Runs in node.js and all browsers.
+* Registered as a [ComponentJS](https://github.com/component/component) [component](https://github.com/component/component/wiki/Components) ('broofa/node-uuid').
+* Cryptographically strong random # generation on supporting platforms
+* 1.1K minified and gzip'ed  (Want something smaller?  Check this [crazy shit](https://gist.github.com/982883) out! )
+* [Annotated source code](http://broofa.github.com/node-uuid/docs/uuid.html)
+* Comes with a Command Line Interface for generating uuids on the command line
+
+## Getting Started
+
+Install it in your browser:
+
+```html
+<script src="uuid.js"></script>
+```
+
+Or in node.js:
+
+```
+npm install node-uuid
+```
+
+```javascript
+var uuid = require('node-uuid');
+```
+
+Then create some ids ...
+
+```javascript
+// Generate a v1 (time-based) id
+uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+
+// Generate a v4 (random) id
+uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'
+```
+
+## API
+
+### uuid.v1([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v1 (timestamp-based) UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID.  See note 1.
+  * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence.  Default: An internally maintained clockseq is used.
+  * `msecs` - (Number | Date) Time in milliseconds since unix Epoch.  Default: The current time is used.
+  * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Notes:
+
+1. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v1({
+  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
+  clockseq: 0x1234,
+  msecs: new Date('2011-11-01').getTime(),
+  nsecs: 5678
+});   // -> "710b962e-041c-11e1-9234-0123456789ab"
+```
+
+Example: In-place generation of two binary IDs
+
+```javascript
+// Generate two ids in an array
+var arr = new Array(32); // -> []
+uuid.v1(null, arr, 0);   // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15]
+uuid.v1(null, arr, 16);  // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15 02 a3 1c b0 14 32 11 e1 85 58 0b 48 8e 4f c1 15]
+
+// Optionally use uuid.unparse() to get stringify the ids
+uuid.unparse(buffer);    // -> '02a2ce90-1432-11e1-8558-0b488e4fc115'
+uuid.unparse(buffer, 16) // -> '02a31cb0-1432-11e1-8558-0b488e4fc115'
+```
+
+### uuid.v4([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v4 UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values
+  * `rng` - (Function) Random # generator to use.  Set to one of the built-in generators - `uuid.mathRNG` (all platforms), `uuid.nodeRNG` (node.js only), `uuid.whatwgRNG` (WebKit only) - or a custom function that returns an array[16] of byte values.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v4({
+  random: [
+    0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,
+    0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36
+  ]
+});
+// -> "109156be-c4fb-41ea-b1b4-efe1671c5836"
+```
+
+Example: Generate two IDs in a single buffer
+
+```javascript
+var buffer = new Array(32); // (or 'new Buffer' in node.js)
+uuid.v4(null, buffer, 0);
+uuid.v4(null, buffer, 16);
+```
+
+### uuid.parse(id[, buffer[, offset]])
+### uuid.unparse(buffer[, offset])
+
+Parse and unparse UUIDs
+
+  * `id` - (String) UUID(-like) string
+  * `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written. Default: A new Array or Buffer is used
+  * `offset` - (Number) Starting index in `buffer` at which to begin writing. Default: 0
+
+Example parsing and unparsing a UUID string
+
+```javascript
+var bytes = uuid.parse('797ff043-11eb-11e1-80d6-510998755d10'); // -> <Buffer 79 7f f0 43 11 eb 11 e1 80 d6 51 09 98 75 5d 10>
+var string = uuid.unparse(bytes); // -> '797ff043-11eb-11e1-80d6-510998755d10'
+```
+
+### uuid.noConflict()
+
+(Browsers only) Set `uuid` property back to it's previous value.
+
+Returns the node-uuid object.
+
+Example:
+
+```javascript
+var myUuid = uuid.noConflict();
+myUuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+```
+
+## Deprecated APIs
+
+Support for the following v1.2 APIs is available in v1.3, but is deprecated and will be removed in the next major version.
+
+### uuid([format [, buffer [, offset]]])
+
+uuid() has become uuid.v4(), and the `format` argument is now implicit in the `buffer` argument. (i.e. if you specify a buffer, the format is assumed to be binary).
+
+### uuid.BufferClass
+
+The class of container created when generating binary uuid data if no buffer argument is specified.  This is expected to go away, with no replacement API.
+
+## Command Line Interface
+
+To use the executable, it's probably best to install this library globally.
+
+`npm install -g node-uuid`
+
+Usage:
+
+```
+USAGE: uuid [version] [options]
+
+
+options:
+
+--help                     Display this message and exit
+```
+
+`version` must be an RFC4122 version that is supported by this library, which is currently version 1 and version 4 (denoted by "v1" and "v4", respectively). `version` defaults to version 4 when not supplied.
+
+### Examples
+
+```
+> uuid
+3a91f950-dec8-4688-ba14-5b7bbfc7a563
+```
+
+```
+> uuid v1
+9d0b43e0-7696-11e3-964b-250efa37a98e
+```
+
+```
+> uuid v4
+6790ac7c-24ac-4f98-8464-42f6d98a53ae
+```
+
+## Testing
+
+In node.js
+
+```
+npm test
+```
+
+In Browser
+
+```
+open test/test.html
+```
+
+### Benchmarking
+
+Requires node.js
+
+```
+npm install uuid uuid-js
+node benchmark/benchmark.js
+```
+
+For a more complete discussion of node-uuid performance, please see the `benchmark/README.md` file, and the [benchmark wiki](https://github.com/broofa/node-uuid/wiki/Benchmark)
+
+For browser performance [checkout the JSPerf tests](http://jsperf.com/node-uuid-performance).
+

+# qs
+
+A querystring parsing and stringifying library with some added security.
+
+[![Build Status](https://secure.travis-ci.org/hapijs/qs.svg)](http://travis-ci.org/hapijs/qs)
+
+Lead Maintainer: [Nathan LaFreniere](https://github.com/nlf)
+
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
+
+## Usage
+
+```javascript
+var Qs = require('qs');
+
+var obj = Qs.parse('a=c');    // { a: 'c' }
+var str = Qs.stringify(obj);  // 'a=c'
+```
+
+### Parsing Objects
+
+```javascript
+Qs.parse(string, [options]);
+```
+
+**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
+For example, the string `'foo[bar]=baz'` converts to:
+
+```javascript
+{
+  foo: {
+    bar: 'baz'
+  }
+}
+```
+
+URI encoded strings work too:
+
+```javascript
+Qs.parse('a%5Bb%5D=c');
+// { a: { b: 'c' } }
+```
+
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
+
+```javascript
+{
+  foo: {
+    bar: {
+      baz: 'foobarbaz'
+    }
+  }
+}
+```
+
+By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
+`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
+
+```javascript
+{
+  a: {
+    b: {
+      c: {
+        d: {
+          e: {
+            f: {
+              '[g][h][i]': 'j'
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+This depth can be overridden by passing a `depth` option to `Qs.parse(string, [options])`:
+
+```javascript
+Qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
+// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }
+```
+
+The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
+
+For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
+
+```javascript
+Qs.parse('a=b&c=d', { parameterLimit: 1 });
+// { a: 'b' }
+```
+
+An optional delimiter can also be passed:
+
+```javascript
+Qs.parse('a=b;c=d', { delimiter: ';' });
+// { a: 'b', c: 'd' }
+```
+
+Delimiters can be a regular expression too:
+
+```javascript
+Qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
+// { a: 'b', c: 'd', e: 'f' }
+```
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+Qs.parse('a[]=b&a[]=c');
+// { a: ['b', 'c'] }
+```
+
+You may specify an index as well:
+
+```javascript
+Qs.parse('a[1]=c&a[0]=b');
+// { a: ['b', 'c'] }
+```
+
+Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
+to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
+their order:
+
+```javascript
+Qs.parse('a[1]=b&a[15]=c');
+// { a: ['b', 'c'] }
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+Qs.parse('a[]=&a[]=b');
+// { a: ['', 'b'] }
+Qs.parse('a[0]=b&a[1]=&a[2]=c');
+// { a: ['b', '', 'c'] }
+```
+
+**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
+instead be converted to an object with the index as the key:
+
+```javascript
+Qs.parse('a[100]=b');
+// { a: { '100': 'b' } }
+```
+
+This limit can be overridden by passing an `arrayLimit` option:
+
+```javascript
+Qs.parse('a[1]=b', { arrayLimit: 0 });
+// { a: { '1': 'b' } }
+```
+
+To disable array parsing entirely, set `arrayLimit` to `-1`.
+
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+Qs.parse('a[0]=b&a[b]=c');
+// { a: { '0': 'b', b: 'c' } }
+```
+
+You can also create arrays of objects:
+
+```javascript
+Qs.parse('a[][b]=c');
+// { a: [{ b: 'c' }] }
+```
+
+### Stringifying
+
+```javascript
+Qs.stringify(object, [options]);
+```
+
+When stringifying, **qs** always URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+Qs.stringify({ a: 'b' });
+// 'a=b'
+Qs.stringify({ a: { b: 'c' } });
+// 'a%5Bb%5D=c'
+```
+
+Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
+
+When arrays are stringified, by default they are given explicit indices:
+
+```javascript
+Qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+You may override this by setting the `indices` option to `false`:
+
+```javascript
+Qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
+// 'a=b&a=c&a=d'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+Qs.stringify({ a: '' });
+// 'a='
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+Qs.stringify({ a: null, b: undefined });
+// 'a='
+```
+
+The delimiter may be overridden with stringify as well:
+
+```javascript
+Qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' });
+// 'a=b;c=d'
+```

+  "readme": "# qs\n\nA querystring parsing and stringifying library with some added security.\n\n[![Build Status](https://secure.travis-ci.org/hapijs/qs.svg)](http://travis-ci.org/hapijs/qs)\n\nLead Maintainer: [Nathan LaFreniere](https://github.com/nlf)\n\nThe **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).\n\n## Usage\n\n```javascript\nvar Qs = require('qs');\n\nvar obj = Qs.parse('a=c');    // { a: 'c' }\nvar str = Qs.stringify(obj);  // 'a=c'\n```\n\n### Parsing Objects\n\n```javascript\nQs.parse(string, [options]);\n```\n\n**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.\nFor example, the string `'foo[bar]=baz'` converts to:\n\n```javascript\n{\n  foo: {\n    bar: 'baz'\n  }\n}\n```\n\nURI encoded strings work too:\n\n```javascript\nQs.parse('a%5Bb%5D=c');\n// { a: { b: 'c' } }\n```\n\nYou can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:\n\n```javascript\n{\n  foo: {\n    bar: {\n      baz: 'foobarbaz'\n    }\n  }\n}\n```\n\nBy default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like\n`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:\n\n```javascript\n{\n  a: {\n    b: {\n      c: {\n        d: {\n          e: {\n            f: {\n              '[g][h][i]': 'j'\n            }\n          }\n        }\n      }\n    }\n  }\n}\n```\n\nThis depth can be overridden by passing a `depth` option to `Qs.parse(string, [options])`:\n\n```javascript\nQs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });\n// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }\n```\n\nThe depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.\n\nFor similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:\n\n```javascript\nQs.parse('a=b&c=d', { parameterLimit: 1 });\n// { a: 'b' }\n```\n\nAn optional delimiter can also be passed:\n\n```javascript\nQs.parse('a=b;c=d', { delimiter: ';' });\n// { a: 'b', c: 'd' }\n```\n\nDelimiters can be a regular expression too:\n\n```javascript\nQs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });\n// { a: 'b', c: 'd', e: 'f' }\n```\n\n### Parsing Arrays\n\n**qs** can also parse arrays using a similar `[]` notation:\n\n```javascript\nQs.parse('a[]=b&a[]=c');\n// { a: ['b', 'c'] }\n```\n\nYou may specify an index as well:\n\n```javascript\nQs.parse('a[1]=c&a[0]=b');\n// { a: ['b', 'c'] }\n```\n\nNote that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number\nto create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving\ntheir order:\n\n```javascript\nQs.parse('a[1]=b&a[15]=c');\n// { a: ['b', 'c'] }\n```\n\nNote that an empty string is also a value, and will be preserved:\n\n```javascript\nQs.parse('a[]=&a[]=b');\n// { a: ['', 'b'] }\nQs.parse('a[0]=b&a[1]=&a[2]=c');\n// { a: ['b', '', 'c'] }\n```\n\n**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will\ninstead be converted to an object with the index as the key:\n\n```javascript\nQs.parse('a[100]=b');\n// { a: { '100': 'b' } }\n```\n\nThis limit can be overridden by passing an `arrayLimit` option:\n\n```javascript\nQs.parse('a[1]=b', { arrayLimit: 0 });\n// { a: { '1': 'b' } }\n```\n\nTo disable array parsing entirely, set `arrayLimit` to `-1`.\n\nIf you mix notations, **qs** will merge the two items into an object:\n\n```javascript\nQs.parse('a[0]=b&a[b]=c');\n// { a: { '0': 'b', b: 'c' } }\n```\n\nYou can also create arrays of objects:\n\n```javascript\nQs.parse('a[][b]=c');\n// { a: [{ b: 'c' }] }\n```\n\n### Stringifying\n\n```javascript\nQs.stringify(object, [options]);\n```\n\nWhen stringifying, **qs** always URI encodes output. Objects are stringified as you would expect:\n\n```javascript\nQs.stringify({ a: 'b' });\n// 'a=b'\nQs.stringify({ a: { b: 'c' } });\n// 'a%5Bb%5D=c'\n```\n\nExamples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.\n\nWhen arrays are stringified, by default they are given explicit indices:\n\n```javascript\nQs.stringify({ a: ['b', 'c', 'd'] });\n// 'a[0]=b&a[1]=c&a[2]=d'\n```\n\nYou may override this by setting the `indices` option to `false`:\n\n```javascript\nQs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });\n// 'a=b&a=c&a=d'\n```\n\nEmpty strings and null values will omit the value, but the equals sign (=) remains in place:\n\n```javascript\nQs.stringify({ a: '' });\n// 'a='\n```\n\nProperties that are set to `undefined` will be omitted entirely:\n\n```javascript\nQs.stringify({ a: null, b: undefined });\n// 'a='\n```\n\nThe delimiter may be overridden with stringify as well:\n\n```javascript\nQs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' });\n// 'a=b;c=d'\n```\n",

+# Decode streams into strings The Right Way(tm)
+
+```javascript
+var fs   = require('fs')
+var zlib = require('zlib')
+var strs = require('stringstream')
+
+var utf8Stream = fs.createReadStream('massiveLogFile.gz')
+  .pipe(zlib.createGunzip())
+  .pipe(strs('utf8'))
+```
+
+No need to deal with `setEncoding()` weirdness, just compose streams
+like they were supposed to be!
+
+Handles input and output encoding:
+
+```javascript
+// Stream from utf8 to hex to base64... Why not, ay.
+var hex64Stream = fs.createReadStream('myFile')
+  .pipe(strs('utf8', 'hex'))
+  .pipe(strs('hex', 'base64'))
+```
+
+Also deals with `base64` output correctly by aligning each emitted data
+chunk so that there are no dangling `=` characters:
+
+```javascript
+var stream = fs.createReadStream('myFile').pipe(strs('base64'))
+
+var base64Str = ''
+
+stream.on('data', function(data) { base64Str += data })
+stream.on('end', function() {

+  console.log('Original file is: ' + new Buffer(base64Str, 'base64'))

+# Synopsis
+
+``` javascript
+var tough = require('tough-cookie'); // note: not 'cookie', 'cookies' or 'node-cookie'
+var Cookie = tough.Cookie;
+var cookie = Cookie.parse(header);
+cookie.value = 'somethingdifferent';
+header = cookie.toString();
+
+var cookiejar = new tough.CookieJar();
+cookiejar.setCookie(cookie, 'http://currentdomain.example.com/path', cb);
+// ...
+cookiejar.getCookies('http://example.com/otherpath',function(err,cookies) {
+  res.headers['cookie'] = cookies.join('; ');
+});
+```
+
+# Installation
+
+It's _so_ easy!
+
+`npm install tough-cookie`
+
+Requires `punycode`, which should get installed automatically for you.  Note that node.js v0.6.2+ bundles punycode by default.
+
+Why the name?  NPM modules `cookie`, `cookies` and `cookiejar` were already taken.
+
+# API
+
+tough
+=====
+
+Functions on the module you get from `require('tough-cookie')`.  All can be used as pure functions and don't need to be "bound".
+
+parseDate(string[,strict])
+-----------------
+
+Parse a cookie date string into a `Date`.  Parses according to RFC6265 Section 5.1.1, not `Date.parse()`.  If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. "Thu, 01 Jan 1970 00:00:010 GMT" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid).
+
+formatDate(date)
+----------------
+
+Format a Date into a RFC1123 string (the RFC6265-recommended format).
+
+canonicalDomain(str)
+--------------------
+
+Transforms a domain-name into a canonical domain-name.  The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265).  For the most part, this function is idempotent (can be run again on its output without ill effects).
+
+domainMatch(str,domStr[,canonicalize=true])
+-------------------------------------------
+
+Answers "does this real domain match the domain in a cookie?".  The `str` is the "current" domain-name and the `domStr` is the "cookie" domain-name.  Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a "suffix match".
+
+The `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not.
+
+defaultPath(path)
+-----------------
+
+Given a current request/response path, gives the Path apropriate for storing in a cookie.  This is basically the "directory" of a "file" in the path, but is specified by Section 5.1.4 of the RFC.
+
+The `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.).  This is the `.pathname` property of node's `uri.parse()` output.
+
+pathMatch(reqPath,cookiePath)
+-----------------------------
+
+Answers "does the request-path path-match a given cookie-path?" as per RFC6265 Section 5.1.4.  Returns a boolean.
+
+This is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.
+
+parse(header[,strict=false])
+----------------------------
+
+alias for `Cookie.parse(header[,strict])`
+
+fromJSON(string)
+----------------
+
+alias for `Cookie.fromJSON(string)`
+
+getPublicSuffix(hostname)
+-------------------------
+
+Returns the public suffix of this hostname.  The public suffix is the shortest domain-name upon which a cookie can be set.  Returns `null` if the hostname cannot have cookies set for it.
+
+For example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.
+
+For further information, see http://publicsuffix.org/.  This module derives its list from that site.
+
+cookieCompare(a,b)
+------------------
+
+For use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2).  Longest `.path`s go first, then sorted oldest to youngest.
+
+``` javascript
+var cookies = [ /* unsorted array of Cookie objects */ ];
+cookies = cookies.sort(cookieCompare);
+```
+
+permuteDomain(domain)
+---------------------
+
+Generates a list of all possible domains that `domainMatch()` the parameter.  May be handy for implementing cookie stores.
+
+
+permutePath(path)
+-----------------
+
+Generates a list of all possible paths that `pathMatch()` the parameter.  May be handy for implementing cookie stores.
+
+Cookie
+======
+
+Cookie.parse(header[,strict=false])
+-----------------------------------
+
+Parses a single Cookie or Set-Cookie HTTP header into a `Cookie` object.  Returns `undefined` if the string can't be parsed.  If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265.  Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off.
+
+Here's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:
+
+``` javascript
+if (res.headers['set-cookie'] instanceof Array)
+  cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); });
+else
+  cookies = [Cookie.parse(res.headers['set-cookie'])];
+```
+
+Cookie.fromJSON(string)
+-----------------------
+
+Convert a JSON string to a `Cookie` object.  Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects.
+
+Properties
+==========
+
+  * _key_ - string - the name or key of the cookie (default "")
+  * _value_ - string - the value of the cookie (default "")
+  * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `"Infinity"`). See `setExpires()`
+  * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie.  May also be set to strings `"Infinity"` and `"-Infinity"` for non-expiry and immediate-expiry, respectively.  See `setMaxAge()`
+  * _domain_ - string - the `Domain=` attribute of the cookie
+  * _path_ - string - the `Path=` of the cookie
+  * _secure_ - boolean - the `Secure` cookie flag
+  * _httpOnly_ - boolean - the `HttpOnly` cookie flag
+  * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)
+
+After a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:
+
+  * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)
+  * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.
+  * _created_ - `Date` - when this cookie was added to the jar
+  * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented.  Using `cookiejar.getCookies(...)` will update this attribute.
+
+Construction([{options}])
+------------
+
+Receives an options object that can contain any Cookie properties, uses the default for unspecified properties.
+
+.toString()
+-----------
+
+encode to a Set-Cookie header value.  The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.
+
+.cookieString()
+---------------
+
+encode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').
+
+.setExpires(String)
+-------------------
+
+sets the expiry based on a date-string passed through `parseDate()`.  If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `"Infinity"` (a string) is set.
+
+.setMaxAge(number)
+-------------------
+
+sets the maxAge in seconds.  Coerces `-Infinity` to `"-Infinity"` and `Infinity` to `"Infinity"` so it JSON serializes correctly.
+
+.expiryTime([now=Date.now()])
+-----------------------------
+
+.expiryDate([now=Date.now()])
+-----------------------------
+
+expiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object.  Note that in both cases the `now` parameter should be milliseconds.
+
+Max-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute.
+
+If Expires (`.expires`) is set, that's returned.
+
+Otherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for "Tue, 19 Jan 2038 03:14:07 GMT" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).
+
+.TTL([now=Date.now()])
+---------
+
+compute the TTL relative to `now` (milliseconds).  The same precedence rules as for `expiryTime`/`expiryDate` apply.
+
+The "number" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired.  Otherwise a time-to-live in milliseconds is returned.
+
+.canonicalizedDoman()
+---------------------
+
+.cdomain()
+----------
+
+return the canonicalized `.domain` field.  This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.
+
+.validate()
+-----------
+
+Status: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.
+
+validates cookie attributes for semantic correctness.  Useful for "lint" checking any Set-Cookie headers you generate.  For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:
+
+``` javascript
+if (cookie.validate() === true) {
+  // it's tasty
+} else {
+  // yuck!
+}
+```
+
+CookieJar
+=========
+
+Construction([store = new MemoryCookieStore()][, rejectPublicSuffixes])
+------------
+
+Simply use `new CookieJar()`.  If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.
+
+
+Attributes
+----------
+
+  * _rejectPublicSuffixes_ - boolean - reject cookies with domains like "com" and "co.uk" (default: `true`)
+
+Since eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.
+
+.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))
+-------------------------------------------------------------------
+
+Attempt to set the cookie in the cookie jar.  If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through.  The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties.
+
+The `options` object can be omitted and can have the following properties:
+
+  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.
+  * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
+  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
+  * _strict_ - boolean - default `false` - perform extra checks
+  * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains.  CookieStore errors aren't ignored by this option.
+
+As per the RFC, the `.hostOnly` property is set if there was no "Domain=" parameter in the cookie string (or `.domain` was null on the Cookie object).  The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case.  Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).
+
+.setCookieSync(cookieOrString, currentUrl, [{options}])
+-------------------------------------------------------
+
+Synchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
+
+.storeCookie(cookie, [{options},] cb(err,cookie))
+-------------------------------------------------
+
+__REMOVED__ removed in lieu of the CookieStore API below
+
+.getCookies(currentUrl, [{options},] cb(err,cookies))
+-----------------------------------------------------
+
+Retrieve the list of cookies that can be sent in a Cookie header for the current url.
+
+If an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed.  The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.
+
+The `options` object can be omitted and can have the following properties:
+
+  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.
+  * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
+  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
+  * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store.  Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).
+  * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it).
+
+The `.lastAccessed` property of the returned cookies will have been updated.
+
+.getCookiesSync(currentUrl, [{options}])
+----------------------------------------
+
+Synchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
+
+.getCookieString(...)
+---------------------
+
+Accepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback.  Simply maps the `Cookie` array via `.cookieString()`.
+
+.getCookieStringSync(...)
+-------------------------
+
+Synchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
+
+.getSetCookieStrings(...)
+-------------------------
+
+Returns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`.  Simply maps the cookie array via `.toString()`.
+
+.getSetCookieStringsSync(...)
+-----------------------------
+
+Synchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
+
+Store
+=====
+
+Base class for CookieJar stores.
+
+# CookieStore API
+
+The storage model for each `CookieJar` instance can be replaced with a custom implementation.  The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file.  The API uses continuation-passing-style to allow for asynchronous stores.
+
+Stores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`.  Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used.
+
+All `domain` parameters will have been normalized before calling.
+
+The Cookie store must have all of the following methods.
+
+store.findCookie(domain, path, key, cb(err,cookie))
+---------------------------------------------------
+
+Retrieve a cookie with the given domain, path and key (a.k.a. name).  The RFC maintains that exactly one of these cookies should exist in a store.  If the store is using versioning, this means that the latest/newest such cookie should be returned.
+
+Callback takes an error and the resulting `Cookie` object.  If no cookie is found then `null` MUST be passed instead (i.e. not an error).
+
+store.findCookies(domain, path, cb(err,cookies))
+------------------------------------------------
+
+Locates cookies matching the given domain and path.  This is most often called in the context of `cookiejar.getCookies()` above.
+
+If no cookies are found, the callback MUST be passed an empty array.
+
+The resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method.  However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.
+
+As of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`.  If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).
+
+store.putCookie(cookie, cb(err))
+--------------------------------
+
+Adds a new cookie to the store.  The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.
+
+The `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.
+
+Pass an error if the cookie cannot be stored.
+
+store.updateCookie(oldCookie, newCookie, cb(err))
+-------------------------------------------------
+
+Update an existing cookie.  The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`.  The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.
+
+The `.lastAccessed` property will always be different between the two objects and `.created` will always be the same.  Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion).
+
+Stores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie.  If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.
+
+The `newCookie` and `oldCookie` objects MUST NOT be modified.
+
+Pass an error if the newCookie cannot be stored.
+
+store.removeCookie(domain, path, key, cb(err))
+----------------------------------------------
+
+Remove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).
+
+The implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.
+
+store.removeCookies(domain, path, cb(err))
+------------------------------------------
+
+Removes matching cookies from the store.  The `path` paramter is optional, and if missing means all paths in a domain should be removed.
+
+Pass an error ONLY if removing any existing cookies failed.
+
+# TODO
+
+  * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()`
+    * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891
+  * better tests for `validate()`?

+# Punycode.js [![Build status](https://travis-ci.org/bestiejs/punycode.js.svg?branch=master)](https://travis-ci.org/bestiejs/punycode.js) [![Code coverage status](http://img.shields.io/coveralls/bestiejs/punycode.js/master.svg)](https://coveralls.io/r/bestiejs/punycode.js) [![Dependency status](https://gemnasium.com/bestiejs/punycode.js.svg)](https://gemnasium.com/bestiejs/punycode.js)
+
+A robust Punycode converter that fully complies to [RFC 3492](http://tools.ietf.org/html/rfc3492) and [RFC 5891](http://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
+
+This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
+
+* [The C example code from RFC 3492](http://tools.ietf.org/html/rfc3492#appendix-C)
+* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
+* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
+* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
+* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
+
+This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc).
+
+## Installation
+
+Via [npm](http://npmjs.org/) (only required for Node.js releases older than v0.6.2):
+
+```bash
+npm install punycode
+```
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install punycode
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install bestiejs/punycode.js
+```
+
+In a browser:
+
+```html
+<script src="punycode.js"></script>
+```
+
+In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
+
+```js
+var punycode = require('punycode');
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('punycode.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'punycode': 'path/to/punycode'
+    }
+  },
+  ['punycode'],
+  function(punycode) {
+    console.log(punycode);
+  }
+);
+```
+
+## API
+
+### `punycode.decode(string)`
+
+Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
+
+```js
+// decode domain name parts
+punycode.decode('maana-pta'); // 'mañana'
+punycode.decode('--dqo34k'); // '☃-⌘'
+```
+
+### `punycode.encode(string)`
+
+Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
+
+```js
+// encode domain name parts
+punycode.encode('mañana'); // 'maana-pta'
+punycode.encode('☃-⌘'); // '--dqo34k'
+```
+
+### `punycode.toUnicode(input)`
+
+Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
+
+```js
+// decode domain names
+punycode.toUnicode('xn--maana-pta.com');
+// → 'mañana.com'
+punycode.toUnicode('xn----dqo34k.com');
+// → '☃-⌘.com'
+
+// decode email addresses
+punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
+// → 'джумла@джpумлатест.bрфa'
+```
+
+### `punycode.toASCII(input)`
+
+Converts a Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that's already in ASCII.
+
+```js
+// encode domain names
+punycode.toASCII('mañana.com');
+// → 'xn--maana-pta.com'
+punycode.toASCII('☃-⌘.com');
+// → 'xn----dqo34k.com'
+
+// encode email addresses
+punycode.toASCII('джумла@джpумлатест.bрфa');
+// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
+```
+
+### `punycode.ucs2`
+
+#### `punycode.ucs2.decode(string)`
+
+Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
+
+```js
+punycode.ucs2.decode('abc');
+// → [0x61, 0x62, 0x63]
+// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
+punycode.ucs2.decode('\uD834\uDF06');
+// → [0x1D306]
+```
+
+#### `punycode.ucs2.encode(codePoints)`
+
+Creates a string based on an array of numeric code point values.
+
+```js
+punycode.ucs2.encode([0x61, 0x62, 0x63]);
+// → 'abc'
+punycode.ucs2.encode([0x1D306]);
+// → '\uD834\uDF06'
+```
+
+### `punycode.version`
+
+A string representing the current Punycode.js version number.
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
+
+To generate the code coverage report, use `grunt cover`.
+
+Feel free to fork if you see possible improvements!

Note that node.js v0.6.2+ bundles punycode by default.\n\nWhy the name?  NPM modules `cookie`, `cookies` and `cookiejar` were already taken.\n\n# API\n\ntough\n=====\n\nFunctions on the module you get from `require('tough-cookie')`.  All can be used as pure functions and don't need to be \"bound\".\n\nparseDate(string[,strict])\n-----------------\n\nParse a cookie date string into a `Date`.  Parses according to RFC6265 Section 5.1.1, not `Date.parse()`.  If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. \"Thu, 01 Jan 1970 00:00:010 GMT\" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid).\n\nformatDate(date)\n----------------\n\nFormat a Date into a RFC1123 string (the RFC6265-recommended format).\n\ncanonicalDomain(str)\n--------------------\n\nTransforms a domain-name into a canonical domain-name.  The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265).  For the most part, this function is idempotent (can be run again on its output without ill effects).\n\ndomainMatch(str,domStr[,canonicalize=true])\n-------------------------------------------\n\nAnswers \"does this real domain match the domain in a cookie?\".  The `str` is the \"current\" domain-name and the `domStr` is the \"cookie\" domain-name.  Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a \"suffix match\".\n\nThe `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not.\n\ndefaultPath(path)\n-----------------\n\nGiven a current request/response path, gives the Path apropriate for storing in a cookie.  This is basically the \"directory\" of a \"file\" in the path, but is specified by Section 5.1.4 of the RFC.\n\nThe `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.).  This is the `.pathname` property of node's `uri.parse()` output.\n\npathMatch(reqPath,cookiePath)\n-----------------------------\n\nAnswers \"does the request-path path-match a given cookie-path?\" as per RFC6265 Section 5.1.4.  Returns a boolean.\n\nThis is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.\n\nparse(header[,strict=false])\n----------------------------\n\nalias for `Cookie.parse(header[,strict])`\n\nfromJSON(string)\n----------------\n\nalias for `Cookie.fromJSON(string)`\n\ngetPublicSuffix(hostname)\n-------------------------\n\nReturns the public suffix of this hostname.  The public suffix is the shortest domain-name upon which a cookie can be set.  Returns `null` if the hostname cannot have cookies set for it.\n\nFor example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.\n\nFor further information, see http://publicsuffix.org/.  This module derives its list from that site.\n\ncookieCompare(a,b)\n------------------\n\nFor use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2).  Longest `.path`s go first, then sorted oldest to youngest.\n\n``` javascript\nvar cookies = [ /* unsorted array of Cookie objects */ ];\ncookies = cookies.sort(cookieCompare);\n```\n\npermuteDomain(domain)\n---------------------\n\nGenerates a list of all possible domains that `domainMatch()` the parameter.  May be handy for implementing cookie stores.\n\n\npermutePath(path)\n-----------------\n\nGenerates a list of all possible paths that `pathMatch()` the parameter.  May be handy for implementing cookie stores.\n\nCookie\n======\n\nCookie.parse(header[,strict=false])\n-----------------------------------\n\nParses a single Cookie or Set-Cookie HTTP header into a `Cookie` object.  Returns `undefined` if the string can't be parsed.  If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265.  Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off.\n\nHere's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:\n\n``` javascript\nif (res.headers['set-cookie'] instanceof Array)\n  cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); });\nelse\n  cookies = [Cookie.parse(res.headers['set-cookie'])];\n```\n\nCookie.fromJSON(string)\n-----------------------\n\nConvert a JSON string to a `Cookie` object.  Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects.\n\nProperties\n==========\n\n  * _key_ - string - the name or key of the cookie (default \"\")\n  * _value_ - string - the value of the cookie (default \"\")\n  * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `\"Infinity\"`). See `setExpires()`\n  * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie.  May also be set to strings `\"Infinity\"` and `\"-Infinity\"` for non-expiry and immediate-expiry, respectively.  See `setMaxAge()`\n  * _domain_ - string - the `Domain=` attribute of the cookie\n  * _path_ - string - the `Path=` of the cookie\n  * _secure_ - boolean - the `Secure` cookie flag\n  * _httpOnly_ - boolean - the `HttpOnly` cookie flag\n  * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)\n\nAfter a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:\n\n  * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)\n  * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.\n  * _created_ - `Date` - when this cookie was added to the jar\n  * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented.  Using `cookiejar.getCookies(...)` will update this attribute.\n\nConstruction([{options}])\n------------\n\nReceives an options object that can contain any Cookie properties, uses the default for unspecified properties.\n\n.toString()\n-----------\n\nencode to a Set-Cookie header value.  The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.\n\n.cookieString()\n---------------\n\nencode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').\n\n.setExpires(String)\n-------------------\n\nsets the expiry based on a date-string passed through `parseDate()`.  If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `\"Infinity\"` (a string) is set.\n\n.setMaxAge(number)\n-------------------\n\nsets the maxAge in seconds.  Coerces `-Infinity` to `\"-Infinity\"` and `Infinity` to `\"Infinity\"` so it JSON serializes correctly.\n\n.expiryTime([now=Date.now()])\n-----------------------------\n\n.expiryDate([now=Date.now()])\n-----------------------------\n\nexpiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object.  Note that in both cases the `now` parameter should be milliseconds.\n\nMax-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute.\n\nIf Expires (`.expires`) is set, that's returned.\n\nOtherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for \"Tue, 19 Jan 2038 03:14:07 GMT\" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).\n\n.TTL([now=Date.now()])\n---------\n\ncompute the TTL relative to `now` (milliseconds).  The same precedence rules as for `expiryTime`/`expiryDate` apply.\n\nThe \"number\" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired.  Otherwise a time-to-live in milliseconds is returned.\n\n.canonicalizedDoman()\n---------------------\n\n.cdomain()\n----------\n\nreturn the canonicalized `.domain` field.  This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.\n\n.validate()\n-----------\n\nStatus: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.\n\nvalidates cookie attributes for semantic correctness.  Useful for \"lint\" checking any Set-Cookie headers you generate.  For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:\n\n``` javascript\nif (cookie.validate() === true) {\n  // it's tasty\n} else {\n  // yuck!\n}\n```\n\nCookieJar\n=========\n\nConstruction([store = new MemoryCookieStore()][, rejectPublicSuffixes])\n------------\n\nSimply use `new CookieJar()`.  If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.\n\n\nAttributes\n----------\n\n  * _rejectPublicSuffixes_ - boolean - reject cookies with domains like \"com\" and \"co.uk\" (default: `true`)\n\nSince eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.\n\n.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))\n-------------------------------------------------------------------\n\nAttempt to set the cookie in the cookie jar.  If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through.  The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties.\n\nThe `options` object can be omitted and can have the following properties:\n\n  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.\n  * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n  * _strict_ - boolean - default `false` - perform extra checks\n  * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains.  CookieStore errors aren't ignored by this option.\n\nAs per the RFC, the `.hostOnly` property is set if there was no \"Domain=\" parameter in the cookie string (or `.domain` was null on the Cookie object).  The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case.  Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).\n\n.setCookieSync(cookieOrString, currentUrl, [{options}])\n-------------------------------------------------------\n\nSynchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.storeCookie(cookie, [{options},] cb(err,cookie))\n-------------------------------------------------\n\n__REMOVED__ removed in lieu of the CookieStore API below\n\n.getCookies(currentUrl, [{options},] cb(err,cookies))\n-----------------------------------------------------\n\nRetrieve the list of cookies that can be sent in a Cookie header for the current url.\n\nIf an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed.  The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.\n\nThe `options` object can be omitted and can have the following properties:\n\n  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.\n  * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n  * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store.  Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).\n  * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it).\n\nThe `.lastAccessed` property of the returned cookies will have been updated.\n\n.getCookiesSync(currentUrl, [{options}])\n----------------------------------------\n\nSynchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getCookieString(...)\n---------------------\n\nAccepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback.  Simply maps the `Cookie` array via `.cookieString()`.\n\n.getCookieStringSync(...)\n-------------------------\n\nSynchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getSetCookieStrings(...)\n-------------------------\n\nReturns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`.  Simply maps the cookie array via `.toString()`.\n\n.getSetCookieStringsSync(...)\n-----------------------------\n\nSynchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\nStore\n=====\n\nBase class for CookieJar stores.\n\n# CookieStore API\n\nThe storage model for each `CookieJar` instance can be replaced with a custom implementation.  The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file.  The API uses continuation-passing-style to allow for asynchronous stores.\n\nStores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`.  Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used.\n\nAll `domain` parameters will have been normalized before calling.\n\nThe Cookie store must have all of the following methods.\n\nstore.findCookie(domain, path, key, cb(err,cookie))\n---------------------------------------------------\n\nRetrieve a cookie with the given domain, path and key (a.k.a. name).  The RFC maintains that exactly one of these cookies should exist in a store.  If the store is using versioning, this means that the latest/newest such cookie should be returned.\n\nCallback takes an error and the resulting `Cookie` object.  If no cookie is found then `null` MUST be passed instead (i.e. not an error).\n\nstore.findCookies(domain, path, cb(err,cookies))\n------------------------------------------------\n\nLocates cookies matching the given domain and path.  This is most often called in the context of `cookiejar.getCookies()` above.\n\nIf no cookies are found, the callback MUST be passed an empty array.\n\nThe resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method.  However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.\n\nAs of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`.  If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).\n\nstore.putCookie(cookie, cb(err))\n--------------------------------\n\nAdds a new cookie to the store.  The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.\n\nThe `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.\n\nPass an error if the cookie cannot be stored.\n\nstore.updateCookie(oldCookie, newCookie, cb(err))\n-------------------------------------------------\n\nUpdate an existing cookie.  The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`.  The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.\n\nThe `.lastAccessed` property will always be different between the two objects and `.created` will always be the same.  Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion).\n\nStores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie.  If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.\n\nThe `newCookie` and `oldCookie` objects MUST NOT be modified.\n\nPass an error if the newCookie cannot be stored.\n\nstore.removeCookie(domain, path, key, cb(err))\n----------------------------------------------\n\nRemove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).\n\nThe implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.\n\nstore.removeCookies(domain, path, cb(err))\n------------------------------------------\n\nRemoves matching cookies from the store.  The `path` paramter is optional, and if missing means all paths in a domain should be removed.\n\nPass an error ONLY if removing any existing cookies failed.\n\n# TODO\n\n  * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()`\n    * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891\n  * better tests for `validate()`?\n\n# Copyright and License\n\n(tl;dr: MIT with some MPL/1.1)\n\nCopyright 2012- GoInstant, Inc. and other contributors.

In these cases the line is printed to the terminal without\nhighlighting it.\n\n### Theme\n\nThe default theme will be used for highlighting.\n\nTo use a different theme, include a `.cardinalrc` file in your `HOME` directory.\n\nThis is a JSON file of the following form:\n\n```json\n{\n  \"theme\": \"hide-semicolons\",\n  \"linenos\": true|false\n}\n```\n\n- `theme` can be the name of any of the [built-in themes](https://github.com/thlorenz/cardinal/tree/master/themes) or the\nfull path to a custom theme anywhere on your computer.\n- linenos toggles line number printing\n\n## API\n\n### *highlight(code[, opts])*\n\n- returns the highlighted version of the passed code ({String}) or throws an error if it was not able to parse it\n- opts (see below)\n\n### *highlightFileSync(fullPath[, opts])*\n\n- returns the highlighted version of the file whose fullPath ({String}) was passed or throws an error if it was not able\n  to parse it\n- opts (see below)\n\n### *highlightFile(fullPath[, opts], callback)*\n\n- calls back with the highlighted version of the file whose fullPath ({String}) was passed or with an error if it was not able\n  to parse it\n- opts (see below)\n- `callback` ({Function}) has the following signature: `function (err, highlighted) { .. }`\n\n### opts\n\nopts is an {Object} with the following properties:\n\n- `theme` {Object} is used to optionally override the theme used to highlight\n- `linenos` {Boolean} if `true` line numbers are included in the highlighted code\n- `firstline` {Integer} sets line number of the first line when line numbers are printed\n- `json` {Boolean} if `true` highlights JSON in addition to JavaScript (`true` by default if file extension is `.json`)\n\n## Examples ([*browse*](https://github.com/thlorenz/cardinal/tree/master/examples))\n\n- [sample .cardinalrc](https://github.com/thlorenz/cardinal/blob/master/examples/.cardinalrc)\n- [highlighting a code snippet](https://github.com/thlorenz/cardinal/blob/master/examples/highlight-string.js) via\n  ***highlight()***\n- [file that highlights itself](https://github.com/thlorenz/cardinal/blob/master/examples/highlight-self.js) via\n  ***highlightFile()*** including line numbers\n- [file that highlights itself hiding all\n  semicolons](https://github.com/thlorenz/cardinal/blob/master/examples/highlight-self-hide-semicolons.js) via\n  ***highlightFileSync()***\n\n\n",

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.png)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instanting the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+## Functions
+
+The top-level exported function has a `cache` property, which is an LRU
+cache set to store 100 items.  So, calling these methods repeatedly
+with the same pattern and options will use the same Minimatch object,
+saving the cost of parsing it multiple times.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma seperated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`.
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']`.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install balanced-match

+concat-map
+==========
+
+Concatenative mapdashery.
+
+[![browser support](http://ci.testling.com/substack/node-concat-map.png)](http://ci.testling.com/substack/node-concat-map)
+
+[![build status](https://secure.travis-ci.org/substack/node-concat-map.png)](http://travis-ci.org/substack/node-concat-map)
+
+example
+=======
+
+``` js
+var concatMap = require('concat-map');
+var xs = [ 1, 2, 3, 4, 5, 6 ];
+var ys = concatMap(xs, function (x) {
+    return x % 2 ? [ x - 0.1, x, x + 0.1 ] : [];
+});
+console.dir(ys);
+```
+
+***
+
+```
+[ 0.9, 1, 1.1, 2.9, 3, 3.1, 4.9, 5, 5.1 ]
+```
+
+methods
+=======
+
+``` js
+var concatMap = require('concat-map')
+```
+
+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.
+
+install
+=======
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install concat-map
+```
+
+license
+=======

+# Change Log
+
+## 0.1.43
+
+* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
+  #148 for some discussion and issues #150, #151, and #152 for implementations.
+
+## 0.1.42
+
+* Fix an issue where `SourceNode`s from different versions of the source-map
+  library couldn't be used in conjunction with each other. See issue #142.
+
+## 0.1.41
+
+* Fix a bug with getting the source content of relative sources with a "./"
+  prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
+
+* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
+  column span of each mapping.
+
+* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
+  all generated positions associated with a given original source and line.
+
+## 0.1.40
+
+* Performance improvements for parsing source maps in SourceMapConsumer.
+
+## 0.1.39
+
+* Fix a bug where setting a source's contents to null before any source content
+  had been set before threw a TypeError. See issue #131.
+
+## 0.1.38
+
+* Fix a bug where finding relative paths from an empty path were creating
+  absolute paths. See issue #129.
+
+## 0.1.37
+
+* Fix a bug where if the source root was an empty string, relative source paths
+  would turn into absolute source paths. Issue #124.
+
+## 0.1.36
+
+* Allow the `names` mapping property to be an empty string. Issue #121.
+
+## 0.1.35
+
+* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
+  to specify a path that relative sources in the second parameter should be
+  relative to. Issue #105.
+
+* If no file property is given to a `SourceMapGenerator`, then the resulting
+  source map will no longer have a `null` file property. The property will
+  simply not exist. Issue #104.
+
+* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
+  Issue #116.
+
+## 0.1.34
+
+* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
+
+* Fix bug involving source contents and the
+  `SourceMapGenerator.prototype.applySourceMap`. Issue #100.
+
+## 0.1.33
+
+* Fix some edge cases surrounding path joining and URL resolution.
+
+* Add a third parameter for relative path to
+  `SourceMapGenerator.prototype.applySourceMap`.
+
+* Fix issues with mappings and EOLs.
+
+## 0.1.32
+
+* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
+  (issue 92).
+
+* Fixed test runner to actually report number of failed tests as its process
+  exit code.
+
+* Fixed a typo when reporting bad mappings (issue 87).
+
+## 0.1.31
+
+* Delay parsing the mappings in SourceMapConsumer until queried for a source
+  location.
+
+* Support Sass source maps (which at the time of writing deviate from the spec

+# Source Map
+
+This is a library to generate and consume the source map format
+[described here][format].
+
+This library is written in the Asynchronous Module Definition format, and works
+in the following environments:
+
+* Modern Browsers supporting ECMAScript 5 (either after the build, or with an
+  AMD loader such as RequireJS)
+
+* Inside Firefox (as a JSM file, after the build)
+
+* With NodeJS versions 0.8.X and higher
+
+## Node
+
+    $ npm install source-map
+
+## Building from Source (for everywhere else)
+
+Install Node and then run
+
+    $ git clone https://fitzgen@github.com/mozilla/source-map.git
+    $ cd source-map
+    $ npm link .
+
+Next, run
+
+    $ node Makefile.dryice.js
+
+This should spew a bunch of stuff to stdout, and create the following files:
+
+* `dist/source-map.js` - The unminified browser version.
+
+* `dist/source-map.min.js` - The minified browser version.
+
+* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.
+
+## Examples
+
+### Consuming a source map
+
+    var rawSourceMap = {
+      version: 3,
+      file: 'min.js',
+      names: ['bar', 'baz', 'n'],
+      sources: ['one.js', 'two.js'],
+      sourceRoot: 'http://example.com/www/js/',
+      mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
+    };
+
+    var smc = new SourceMapConsumer(rawSourceMap);
+
+    console.log(smc.sources);
+    // [ 'http://example.com/www/js/one.js',
+    //   'http://example.com/www/js/two.js' ]
+
+    console.log(smc.originalPositionFor({
+      line: 2,
+      column: 28
+    }));
+    // { source: 'http://example.com/www/js/two.js',
+    //   line: 2,
+    //   column: 10,
+    //   name: 'n' }
+
+    console.log(smc.generatedPositionFor({
+      source: 'http://example.com/www/js/two.js',
+      line: 2,
+      column: 10
+    }));
+    // { line: 2, column: 28 }
+
+    smc.eachMapping(function (m) {
+      // ...
+    });

+### Generating a source map
+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+    function compile(ast) {
+      switch (ast.type) {
+      case 'BinaryExpression':
+        return new SourceNode(
+          ast.location.line,
+          ast.location.column,
+          ast.location.source,
+          [compile(ast.left), " + ", compile(ast.right)]
+        );
+      case 'Literal':
+        return new SourceNode(
+          ast.location.line,
+          ast.location.column,
+          ast.location.source,
+          String(ast.value)
+        );
+      // ...
+      default:
+        throw new Error("Bad AST");
+      }
+    }
+
+    var ast = parse("40 + 2", "add.js");
+    console.log(compile(ast).toStringWithSourceMap({
+      file: 'add.js'
+    }));
+    // { code: '40 + 2',
+    //   map: [object SourceMapGenerator] }
+
+#### With SourceMapGenerator (low level API)
+
+    var map = new SourceMapGenerator({
+      file: "source-mapped.js"
+    });
+
+    map.addMapping({
+      generated: {
+        line: 10,
+        column: 35
+      },
+      source: "foo.js",
+      original: {
+        line: 33,
+        column: 2
+      },
+      name: "christopher"
+    });
+
+    console.log(map.toString());
+    // '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+
+## API
+
+Get a reference to the module:
+
+    // NodeJS
+    var sourceMap = require('source-map');
+
+    // Browser builds
+    var sourceMap = window.sourceMap;
+
+    // Inside Firefox
+    let sourceMap = {};
+    Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referrenced by individual
+  mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.
+
+* `column`: The column number in the generated source.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+  available.
+
+* `line`: The line number in the original source, or null if this information is
+  not available.
+
+* `column`: The column number in the original source, or null or null if this
+  information is not available.
+
+* `name`: The original identifier, or null if this information is not available.
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.
+
+* `column`: The column number in the original source.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.
+
+* `column`: The column number in the generated source, or null.
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source
+and line provided. The only argument is an object with the following
+properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.
+
+* `column`: The column number in the generated source, or null.
+
+#### SourceMapConsumer.prototype.sourceContentFor(source)
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+  name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+  every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+  the mappings sorted by the generated file's line/column order or the
+  original's source/line/column order, respectively. Defaults to
+  `SourceMapConsumer.GENERATED_ORDER`.
+
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+  associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new SourceMapGenerator based on a SourceMapConsumer
+
+* `sourceMapConsumer` The SourceMap.
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimium of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+  If omitted, sourceMapConsumer.file will be used, if it exists.
+  Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+  to be applied. If relative, it is relative to the SourceMap.
+
+  This parameter is needed when the two SourceMaps aren't in the same
+  directory, and the SourceMap to be applied contains relative source
+  paths. If so, those relative source paths need to be rewritten
+  relative to the SourceMap.
+
+  If omitted, it is assumed that both SourceMaps are in the same directory,
+  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+  it isn't associated with an original line.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+  below.
+
+* `name`: Optional. The original identifier.
+
+#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.join(sep)
+
+Like `Array.prototype.join` except for SourceNodes. Inserts the separator
+between each of this source node's children.
+
+* `sep`: The separator.
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming whitespace from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+## Tests
+
+[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](https://travis-ci.org/mozilla/source-map)
+
+Install NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.
+
+To add new tests, create a new file named `test/test-<your new test name>.js`
+and export your test functions with names that start with "test", for example
+
+    exports["test doing the foo bar"] = function (assert, util) {
+      ...
+    };
+
+The new test will be located automatically when you run the suite.
+
+The `util` argument is the test utility module located at `test/source-map/util`.
+
+The `assert` argument is a cut down version of node's assert module. You have
+access to the following assertion functions:
+
+* `doesNotThrow`
+
+* `equal`
+
+* `ok`
+
+* `strictEqual`
+
+* `throws`
+
+(The reason for the restricted set of test functions is because we need the
+tests to run inside Firefox's test suite as well and so the assert module is
+shimmed in that environment. See `build/assert-shim.js`.)

+  * Assure right unicode symbols resolution when processing strings in Array.from
+  * Rely on ES6 symbol shim and use native @@iterator Symbol if provided by environment
+* Add methods:

+  * Array.prototype.values
+  * Array.prototype[@@iterator]
+  * String.prototype[@@iterator]

+Improve documentation
+
+v0.10.2  --  2014.04.24
+- Simplify and deprecate `isCallable`. It seems in ES5 based engines there are
+  no callable objects which are `typeof obj !== 'function'`
+- Update Array.from map callback signature (up to latest resolution of TC39)
+- Improve documentation
+
+v0.10.1  --  2014.04.14
+Bump version for npm
+(Workaround for accidental premature publish & unpublish of v0.10.0 a while ago)
+
+v0.10.0  --  2014.04.13
+Major update:
+- All methods and function specified for ECMAScript 6 are now introduced as
+  shims accompanied with functions through which (optionally) they can be
+  implementend on native objects
+- Filename convention was changed to shorter and strictly lower case names. e.g.
+  `lib/String/prototype/starts-with` became `string/#/starts-with`
+- Generated functions are guaranteed to have expected length
+- Objects with null prototype (created via `Object.create(null)`) are widely
+  supported (older version have crashed due to implied `obj.hasOwnProperty` and
+  related invocations)
+- Support array subclasses
+- When handling lists do not limit its length to Uint32 range
+- Use newly introduced `Object.eq` for strict equality in place of `Object.is`
+- Iteration of Object have been improved so properties that were hidden or
+  removed after iteration started are not iterated.
+
+Additions:
+- `Array.isPlainArray`
+- `Array.validArray`
+- `Array.prototype.concat` (as updated with ES6)

+- `Object.extend` into `Object.assign` (as introduced in ES 6)
+- `Object.extendProperties` into `Object.mixin`, with improved internal
+  handling, so it matches temporarily specified `Object.mixin` for ECMAScript 6
+- `Object.isList` into `Object.isArrayLike`
+- `Object.mapToArray` into `Object.toArray` (with fixed function length)
+- `Object.toPlainObject` into `Object.normalizeOptions` (as this is the real

+v0.9.1  --  2012.09.17
+* Object.reduce - reduce for hash-like collections
+* Accapt any callable object as callback in Object.filter, mapKeys and map
+* Convention cleanup
+
+v0.9.0  --  2012.09.13
+We're getting to real solid API
+
+Removed:
+* Function#memoize - it's grown up to be external package, to be soon published
+  as 'memoizee'
+* String.guid - it doesn't fit es5-ext (extensions) concept, will be provided as
+  external package
+# Function.arguments - obsolete
+# Function.context - obsolete
+# Function#flip - not readable when used, so it was never used
+# Object.clone - obsolete and confusing
+
+Added:
+* String#camelToHyphen - String format convertion
+
+Renamed:
+* String#dashToCamelCase -> String#hyphenToCamel
+
+Fixes:
+* Object.isObject - Quote names in literals that match reserved keywords
+  (older implementations crashed on that)
+* String#repeat - Do not accept negative values (coerce them to 1)
+
+Improvements:
+* Array#remove - Accepts many arguments, we can now remove many values at once
+* Object iterators (forEach, map, some) - Compare function invoked with scope
+  object bound to this
+* Function#curry - Algorithm cleanup
+* Object.isCopy - Support for all types, not just plain objects
+* Object.isPlainObject - Support for cross-frame objects
+* Do not memoize any of the functions, it shouldn't be decided internally
+* Remove Object.freeze calls in reserved, it's not up to convention
+* Improved documentation
+* Better linting (hard-core approach using both JSLint mod and JSHint)
+* Optional arguments are now documented in funtions signature
+
+v0.8.2  --  2012.06.22
+Fix errors in Array's intersection and exclusion methods, related to improper
+usage of contains method
+
+v0.8.1  --  2012.06.13
+Reorganized internal logic of Function.prototype.memoize. So it's more safe now
+and clears cache properly. Additionally preventCache option was provided.
+
+v0.8.0  --  2012.05.28
+Again, major overhaul. Probably last experimental stuff was trashed, all API
+looks more like standard extensions now.
+
+Changes:
+* Turn all Object.prototype extensions into functions and move them to Object
+namespace. We learned that extending Object.prototype is bad idea in any case.
+* Rename Function.prototype.curry into Function.prototype.partial. This function
+  is really doing partial application while currying is slightly different
+  concept.
+* Convert Function.prototype.ncurry to new implementation of
+  Function.prototype.curry, it now serves real curry concept additionaly it
+  covers use cases for aritize and hold, which were removed.
+* Rename Array's peek to last, and provide support for sparse arrays in it
+* Rename Date's monthDaysCount into daysInMonth
+* Simplify object iterators, now order of iteration can be configured with just
+  compareFn argument (no extra byKeys option)
+* Rename Object.isDuplicate to Object.isCopy
+* Rename Object.isEqual to Object.is which is compatible with future 'is'
+  keyword
+* Function.memoize is now Function.prototype.memoize. Additionally clear cache
+  functionality is added, and access to original arguments object.
+* Rename validation functions: assertNotNull to validValue, assertCallable to
+  validCallable. validValue was moved to Object namespace. On success they now
+  return validated value instead of true, it supports better composition.
+  Additionally created Date.validDate and Error.validError
+* All documentation is now held in README.md not in code files.
+* Move guid to String namespace. All guids now start with numbers.
+* Array.generate: fill argument is now optional
+* Object.toArray is now Array.from (as new ES6 specification draft suggests)
+* All methods that rely on indexOf or lastIndexOf, now rely on egal (Object.is)
+  versions of them (eIndexOf, eLastIndexOf)
+* Turn all get* functions that returned methods into actuall methods (get*
+  functionality can still be achieved with help of Function.prototype.partial).
+  So: Date.getFormat is now Date.prototype.format,
+  Number.getPad is now Number.prototype.pad,
+  String.getFormat is now String.prototype.format,
+  String.getIndent is now String.prototype.indent,
+  String.getPad is now String.prototype.pad
+* Refactored Object.descriptor, it is now just two functions, main one and
+  main.gs, main is for describing values, and gs for describing getters and
+  setters. Configuration is passed with first argument as string e.g. 'ce' for
+  configurable and enumerable. If no configuration string is provided then by
+  default it returns configurable and writable but not enumerable for value or
+  configurable but not enumerable for getter/setter
+* Function.prototype.silent now returns prepared function (it was
+  expected to be fixed for 0.7)
+* Reserved keywords map (reserved) is now array not hash.
+* Object.merge is now Object.extend (while former Object.extend was completely
+  removed) - 'extend' implies that we change object, not creating new one (as
+  'merge' may imply). Similarily Object.mergeProperties was renamed to
+  Object.extendProperties
+* Position argument support in Array.prototype.contains and
+  String.prototype.contains (so it follows ES6 specification draft)
+* endPosition argument support in String.prototype.endsWith and fromPosition
+  argument support in String.prototype.startsWith (so it follows ES6
+  specification draft)
+* Better and cleaner String.prototype.indent implementation. No default value
+  for indent string argument, optional nest value (defaults to 1), remove
+  nostart argument
+* Correct length values for most methods (so they reflect length of similar
+  methods in standard)
+* Length argument is now optional in number and string pad methods.
+* Improve arguments validation in general, so it adheres to standard conventions
+* Fixed format of package.json
+
+Removed methods and functions:
+* Object.prototype.slice - Object is not ordered collection, so slice doesn't
+  make sense.
+* Function's rcurry, rncurry, s - too cumbersome for JS, not many use cases for
+  that
+* Function.prototype.aritize and Function.prototype.hold - same functionality
+  can be achieved with new Function.prototype.curry
+* Function.prototype.log - provided more generic Function.prototype.wrap for
+  same use case
+* getNextIdGenerator - no use case for that (String.guid should be used if
+  needed)
+* Object.toObject - Can be now acheived with Object(validValue(x))
+* Array.prototype.someValue - no real use case (personally used once and
+  case was already controversial)
+* Date.prototype.duration - moved to external package
+* Number.getAutoincrement - No real use case
+* Object.prototype.extend, Object.prototype.override,
+  Object.prototype.plainCreate, Object.prototype.plainExtend - It was probably
+  too complex, same should be achieved just with Object.create,
+  Object.descriptor and by saving references to super methods in local scope.
+* Object.getCompareBy - Functions should be created individually for each use
+  case
+* Object.get, Object.getSet, Object.set, Object.unset - Not many use cases and
+  same can be easily achieved with simple inline function
+* String.getPrefixWith - Not real use case for something that can be easily
+  achieved with '+' operator
+* Object.isPrimitive - It's just negation of Object.isObject
+* Number.prototype.isLess, Number.prototype.isLessOrEqual - they shouldn't be in
+  Number namespace and should rather be addressed with simple inline functions.
+* Number.prototype.subtract - Should rather be addressed with simple inline
+  function
+
+New methods and functions:
+* Array.prototype.lastIndex - Returns last declared index in array
+* String.prototype.last - last for strings
+* Function.prototype.wrap - Wrap function with other, it allows to specify
+  before and after behavior transform return value or prevent original function
+  from being called.
+* Math.sign - Returns sign of a number (already in ES6 specification draft)
+* Number.toInt - Converts value to integer (already in ES6 specification draft)
+* Number.isNaN - Returns true if value is NaN (already in ES6 specification
+  draft)
+* Number.toUint - Converts value to unsigned integer
+* Number.toUint32 - Converts value to 32bit unsigned integer
+* Array.prototype.eIndexOf, eLastIndexOf - Egal version (that uses Object.is) of
+  standard methods (all methods that were using native indexOf or lastIndexOf
+  now uses eIndexOf and elastIndexOf respectively)
+* Array.of - as it's specified for ES6
+
+Fixes:
+* Fixed binarySearch so it always returns valid list index
+* Object.isList - it failed on lists that are callable (e.g. NodeList in Nitro
+  engine)
+* Object.map now supports third argument for callback
+
+v0.7.1  --  2012.01.05
+New methods:
+* Array.prototype.firstIndex - returns first valid index of array (for
+	sparse arrays it may not be '0'
+
+Improvements:
+* Array.prototype.first - now returns value for index returned by firstIndex
+* Object.prototype.mapToArray - can be called without callback, then array of
+	key-value pairs is returned
+
+Fixes
+* Array.prototype.forEachRight, object's length read through UInt32 conversion
+
+v0.7.0  --  2011.12.27
+Major update.
+Stepped back from experimental ideas and introduced more standard approach
+taking example from how ES5 methods and functions are designed. One exceptions
+is that, we don’t refrain from declaring methods for Object.prototype - it’s up
+to developer whether how he decides to use it in his context (as function or as
+method).
+
+In general:
+* Removed any method 'functionalization' and functionalize method itself.
+	es5-ext declares plain methods, which can be configured to work as functions
+	with call.bind(method) - see documentation.
+* Removed separation of Object methods for ES5 (with descriptors) and
+	ES3 (plain) - we're following ES5 idea on that, some methods are intended just
+	for enumerable properties and some are for all properties, all are declared
+	for Object.prototype
+* Removed separation of Array generic (collected in List folder) and not generic
+	methods (collected in Array folder). Now all methods are generic and are in
+	Array/prototype folder. This separation also meant, that methods in Array are
+	usually destructive. We don’t do that separation now, there’s generally no use
+	case for destructive iterators, we should be fine with one version of each
+	method, (same as ES5 is fine with  e.g. one, non destructive 'filter' method)
+* Folder structure resembles tree of native ES5 Objects
+* All methods are written with ES5 conventions in mind, it means that most
+	methods are generic and can be run on any object. In more detail:
+	** Array.prototype and Object.prototype methods can be run on any object (any
+		not null or undefined value),
+	** Date.prototype methods should be called only on Date instances.
+	** Function.prototype methods can be called on any callable objects (not
+		necessarily functions)
+	** Number.prototype & String.prototype methods can be called on any value, in
+		case of Number it it’ll be degraded to number, in case of string it’ll be
+		degraded to string.
+* Travis CI support (only for Node v0.6 branch, as v0.4 has buggy V8 version)
+
+Improvements for existing functions and methods:
+* Function.memoize (was Function.cache) is now fully generic, can operate on any
+	type of arguments and it’s NaN safe (all NaN objects are considered equal)
+* Method properties passed to Object.prototype.extend or
+	Object.prototype.override can aside of _super optionally take prototype object
+	via _proto argument
+* Object iterators: forEach, mapToArray and every can now iterate in specified
+	order
+* pluck, invoke and other functions that return reusable functions or methods
+	have now their results memoized.
+
+New methods:
+* Global: assertNotNull, getNextIdGenerator, guid, isEqual, isPrimitive,
+	toObject
+* Array: generate
+* Array.prototype: binarySearch, clear, contains, diff, exclusion, find, first,
+	forEachRight, group, indexesOf, intersection, remove, someRight, someValue
+* Boolean: isBoolean
+* Date: isDate
+* Function: arguments, context, insert, isArguments, remove
+* Function.prototype: not, silent
+* Number: getAutoincrement, isNumber
+* Number.prototype: isLessOrEqual, isLess, subtract
+* Object: assertCallable, descriptor (functions for clean descriptors),
+	getCompareBy, isCallable, isObject
+* Object.prototype: clone (real clone), compact, count, diff, empty,
+	getPropertyNames, get, keyOf, mapKeys, override, plainCreate, plainExtend,
+	slice, some, unset
+* RegExp: isRegExp
+* String: getPrefixWith, isString
+* String.prototype: caseInsensitiveCompare, contains, isNumeric

+	objects

+# es5-ext
+## ECMAScript 5 extensions
+### (with respect to ECMAScript 6 standard)
+
+Shims for upcoming ES6 standard and other goodies implemented strictly with ECMAScript conventions in mind.
+
+It's designed to be used in compliant ECMAScript 5 or ECMAScript 6 environments. Older environments are not supported, although most of the features should work with correct ECMAScript 5 shim on board.
+
+When used in ECMAScript 6 environment, native implementation (if valid) takes precedence over shims.
+
+### Installation
+
+	$ npm install es5-ext
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+#### ECMAScript 6 features
+
+You can force ES6 features to be implemented in your environment, e.g. following will assign `from` function to `Array` (only if it's not implemented already).
+
+```javascript
+require('es5-ext/array/from/implement');
+Array.from('foo'); // ['f', 'o', 'o']
+```
+
+You can also access shims directly, without fixing native objects. Following will return native `Array.from` if it's available and fallback to shim if it's not.
+
+```javascript
+var aFrom = require('es5-ext/array/from');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+If you want to use shim unconditionally (even if native implementation exists) do:
+
+```javascript
+var aFrom = require('es5-ext/array/from/shim');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+##### List of ES6 shims
+
+It's about properties introduced with ES6 and those that have been updated in new spec.

+#### Non ECMAScript standard features
+
+__es5-ext__ provides also other utils, and implements them as if they were proposed for a standard. It mostly offers methods (not functions) which can directly be assigned to native prototypes:
+
+```javascript
+Object.defineProperty(Function.prototype, 'partial', { value: require('es5-ext/function/#/partial'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(Array.prototype, 'flatten', { value: require('es5-ext/array/#/flatten'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(String.prototype, 'capitalize', { value: require('es5-ext/string/#/capitalize'),
+  configurable: true, enumerable: false, writable: true });
+```
+
+See [es5-extend](https://github.com/wookieb/es5-extend#es5-extend), a great utility that automatically will extend natives for you. 
+
+__Important:__ Remember to __not__ extend natives in scope of generic reusable packages (e.g. ones you intend to publish to npm). Extending natives is fine __only__ if you're the _owner_ of the global scope, so e.g. in final project you lead development of.
+
+When you're in situation when native extensions are not good idea, then you should use methods indirectly:
+
+
+```javascript
+var flatten = require('es5-ext/array/#/flatten');
+
+flatten.call([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+for better convenience you can turn methods into functions:
+
+
+```javascript
+var call = Function.prototype.call
+var flatten = call.bind(require('es5-ext/array/#/flatten'));
+
+flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+You can configure custom toolkit (like [underscorejs](http://underscorejs.org/)), and use it throughout your application
+
+```javascript
+var util = {};
+util.partial = call.bind(require('es5-ext/function/#/partial'));
+util.flatten = call.bind(require('es5-ext/array/#/flatten'));
+util.startsWith = call.bind(require('es5-ext/string/#/starts-with'));
+
+util.flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+As with native ones most methods are generic and can be run on any type of object.

+`Object.create` alternative that provides workaround for [V8 issue](http://code.google.com/p/v8/issues/detail?id=2804).
+
+When `null` is provided as a prototype, it's substituted with specially prepared object that derives from Object.prototype but has all Object.prototype properties shadowed with undefined.

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+
+### Tests [![Build Status](https://travis-ci.org/medikoo/es6-iterator.png)](https://travis-ci.org/medikoo/es6-iterator)

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)
+
+	$ npm test

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)
+
+	$ npm test

+
+v0.3.1  --  2014.04.25
+* Fix redefinition of emit method in `pipe`
+* Allow custom emit method name in `pipe`
+
+v0.3.0  --  2014.04.24
+* Move out from lib folder
+* Do not expose all utilities on main module
+* Support objects which do not inherit from Object.prototype
+* Improve arguments validation
+* Improve internals
+* Remove Makefile
+* Improve documentation
+
+v0.2.2  --  2013.06.05
+* `unify` functionality
+
+v0.2.1  --  2012.09.21
+* hasListeners module
+* Simplified internal id (improves performance a little), now it starts with
+  underscore (hint it's private). Abstracted it to external module to have it
+  one place
+* Documentation cleanup
+
+v0.2.0  --  2012.09.19
+* Trashed poor implementation of v0.1 and came up with something solid
+
+Changes:
+* Improved performance
+* Fixed bugs event-emitter is now cross-prototype safe and not affected by
+  unexpected methods attached to Object.prototype
+* Removed support for optional "emitter" argument in `emit` method, it was
+  cumbersome to use, and should be solved just with event objects
+
+v0.1.5  --  2012.08.06
+* (maintanance) Do not use descriptors for internal objects, it exposes V8 bugs
+  (only Node v0.6 branch)
+
+v0.1.4  --  2012.06.13
+* Fix detachment of listeners added with 'once'
+
+v0.1.3  --  2012.05.28
+* Updated es5-ext to latest version (v0.8)
+* Cleared package.json so it's in npm friendly format
+
+v0.1.2  --  2012.01.22
+* Support for emitter argument in emit function, this allows some listeners not
+  to be notified about event
+* allOff - removes all listeners from object
+* All methods returns self object
+* Internal fixes
+* Travis CI integration
+
+v0.1.1  --  2011.08.08
+* Added TAD test suite to devDependencies, configured test commands.
+  Tests can be run with 'make test' or 'npm test'

+# event-emitter
+## Environment agnostic event emitter
+
+### Installation
+
+	$ npm install event-emitter
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+```javascript
+var ee = require('event-emitter');
+
+var emitter = ee({}), listener;
+
+emitter.on('test', listener = function (args) {
+  // …emitter logic
+});
+
+emitter.once('test', function (args) {
+  // …invoked only once(!)
+});
+
+emitter.emit('test', arg1, arg2/*…args*/); // Two above listeners invoked
+emitter.emit('test', arg1, arg2/*…args*/); // Only first listener invoked
+
+emitter.off('test', listener);              // Removed first listener
+emitter.emit('test', arg1, arg2/*…args*/); // No listeners invoked
+```
+### Additional utilities
+
+#### allOff(obj) _(event-emitter/all-off)_
+
+Removes all listeners from given event emitter object
+
+#### hasListeners(obj[, name]) _(event-emitter/has-listeners)_
+
+Whether object has some listeners attached to the object.
+When `name` is provided, it checks listeners for specific event name
+
+```javascript
+var emitter = ee();
+var hasListeners = require('event-emitter/has-listeners');
+var listener = function () {};
+
+hasListeners(emitter); // false
+
+emitter.on('foo', listener);
+hasListeners(emitter); // true
+hasListeners(emitter, 'foo'); // true
+hasListeners(emitter, 'bar'); // false
+
+emitter.off('foo', listener);
+hasListeners(emitter, 'foo'); // false
+```
+
+#### pipe(source, target[, emitMethodName]) _(event-emitter/pipe)_
+
+Pipes all events from _source_ emitter onto _target_ emitter (all events from _source_ emitter will be emitted also on _target_ emitter, but not other way).  
+Returns _pipe_ object which exposes `pipe.close` function. Invoke it to close configured _pipe_.  
+It works internally by redefinition of `emit` method, if in your interface this method is referenced differently, provide its name (or symbol) with third argument.
+
+#### unify(emitter1, emitter2) _(event-emitter/unify)_
+
+Unifies event handling for two objects. Events emitted on _emitter1_ would be also emitter on _emitter2_, and other way back.  
+Non reversible.
+
+```javascript
+var eeUnify = require('event-emitter/unify');
+
+var emitter1 = ee(), listener1, listener3;
+var emitter2 = ee(), listener2, listener4;
+
+emitter1.on('test', listener1 = function () { });
+emitter2.on('test', listener2 = function () { });
+
+emitter1.emit('test'); // Invoked listener1
+emitter2.emit('test'); // Invoked listener2
+
+var unify = eeUnify(emitter1, emitter2);
+
+emitter1.emit('test'); // Invoked listener1 and listener2
+emitter2.emit('test'); // Invoked listener1 and listener2
+
+emitter1.on('test', listener3 = function () { });
+emitter2.on('test', listener4 = function () { });
+
+emitter1.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+emitter2.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+```

Otherwise, pressing backspace will overwrite the prompt\n  with the replacement character, which is weird.\n\n## ms.mute()\n\nSet `muted` to `true`.

+readline2 [![Build Status](https://travis-ci.org/SBoudrias/readline2.png?branch=master)](https://travis-ci.org/SBoudrias/readline2)
+=========
+
+Node.js (v0.8 and v0.10) had some bugs and issues with the default [Readline](http://nodejs.org/api/readline.html) module.
+
+This module include fixes seen in later version (0.11) and ease some undesirable behavior one could see using the readline to create interatives prompts. This means `readline2` change some behaviors and as so is **not** meant to be a drop-in replacement.
+
+This project is extracted from the core of [Inquirer.js interactive prompt interface](https://github.com/SBoudrias/Inquirer.js) to be available as a standalone module.
+
+
+Documentation
+-------------
+
+**Installation**: `npm install --save readline2`
+
+### readline2.createInterface( options ); -> {Interface}
+
+Present the same API as [Node.js `readline.createInterface()`](http://nodejs.org/api/readline.html)
+
+#### Improvements
+- Default `options.input` as `process.stdin`
+- Default `options.output` as `process.stdout`
+- `interface.stdout` is wrapped in a [MuteStream](https://github.com/isaacs/mute-stream)
+- Prevent `up` and `down` keys from moving through history inside the readline
+- Fix cursor position after a line refresh when the `Interface` prompt contains ANSI colors
+

+# ansi-regex [![Build Status](https://travis-ci.org/sindresorhus/ansi-regex.svg?branch=master)](https://travis-ci.org/sindresorhus/ansi-regex)
+
+> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
+
+
+## Install
+
+```sh
+$ npm install --save ansi-regex
+```
+
+
+## Usage
+
+```js
+var ansiRegex = require('ansi-regex');
+
+ansiRegex().test('\u001b[4mcake\u001b[0m');
+//=> true
+
+ansiRegex().test('cake');
+//=> false
+
+'\u001b[4mcake\u001b[0m'.match(ansiRegex());
+//=> ['\u001b[4m', '\u001b[0m']
+```
+
+*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

+# The Reactive Extensions for JavaScript (RxJS) <sup>2.3</sup>... #
+*...is a set of libraries to compose asynchronous and event-based programs using observable collections and [Array#extras](http://blogs.msdn.com/b/ie/archive/2010/12/13/ecmascript-5-part-2-array-extras.aspx) style composition in JavaScript*
+
+The project is actively developed by [Microsoft Open Technologies, Inc.](http://msopentech.com/), in collaboration with a community of open source developers.
+
+## The Need to go Reactive ##
+
+Applications, especially on the web have changed over the years from being a simple static page, to DHTML with animations, to the Ajax revolution.  Each time, we're adding more complexity, more data, and asynchronous behavior to our applications.  How do we manage it all?  How do we scale it?  By moving towards "Reactive Architectures" which are event-driven, resilient and responsive.  With the Reactive Extensions, you have all the tools you need to help build these systems.
+
+## About the Reactive Extensions ##
+
+The Reactive Extensions for JavaScript (RxJS) is a set of libraries for composing asynchronous and event-based programs using observable sequences and fluent query operators that many of you already know by [Array#extras](http://blogs.msdn.com/b/ie/archive/2010/12/13/ecmascript-5-part-2-array-extras.aspx) in JavaScript. Using RxJS, developers represent asynchronous data streams with Observables, query asynchronous data streams using our many operators, and parameterize the concurrency in the asynchronous data streams using Schedulers. Simply put, RxJS = Observables + Operators + Schedulers.
+
+Whether you are authoring a web-based application in JavaScript or a server-side application in Node.js, you have to deal with asynchronous and event-based programming as a matter of course. Although some patterns are emerging such as the Promise pattern, handling exceptions, cancellation, and synchronization is difficult and error-prone.
+
+Using RxJS, you can represent multiple asynchronous data streams (that come from diverse sources, e.g., stock quote, tweets, computer events, web service requests, etc.), and subscribe to the event stream using the Observer object. The Observable notifies the subscribed Observer instance whenever an event occurs.
+
+Because observable sequences are data streams, you can query them using standard query operators implemented by the Observable type. Thus you can filter, project, aggregate, compose and perform time-based operations on multiple events easily by using these operators. In addition, there are a number of other reactive stream specific operators that allow powerful queries to be written. Cancellation, exceptions, and synchronization are also handled gracefully by using the methods on the Observable object.
+
+But the best news of all is that you already know how to program like this.  Take for example the following JavaScript code, where we get some stock data and then manipulate and then iterate the results.
+
+```js
+/* Get stock data somehow */
+var source = getStockData();
+
+source
+  .filter(function (quote) {
+      return quote.price > 30;
+  })
+  .map(function (quote) {
+      return quote.price;
+  })
+  .forEach(function (price) {
+    console.log('Prices higher than $30: $' + price);
+  });
+```
+
+Now what if this data were to come as some sort of event, for example a stream, such as as a WebSocket, then we could pretty much write the same query to iterate our data, with very little change.
+
+```js
+/* Get stock data somehow */
+var source = getAsyncStockData();
+
+var subscription = source
+  .filter(function (quote) {
+    return quote.price > 30;
+  })
+  .map(function (quote) {
+    return quote.price;
+  })
+  .forEach(
+    function (price) {
+      console.log('Prices higher than $30: $' + price);
+    },
+    function (err) {
+      console.log('Something went wrong: ' + err.message);
+    });
+
+/* When we're done */
+subscription.dispose();
+```
+
+The only difference is that we can handle the errors inline with our subscription.  And when we're no longer interested in receiving the data as it comes streaming in, we call `dispose` on our subscription.
+
+## Batteries Included ##
+
+Sure, there are a lot of libraries to get started with RxJS?  Confused on where to get started?  Start out with the complete set of operators with [`rx.all.js`](doc/libraries/rx.complete.md), then you can reduce it to the number of operators that you really need, and perhaps stick with something as small as [`rx.lite.js`](doc/libraries/rx.lite.md).
+
+This set of libraries include:
+
+- [`rx.all.js`](doc/libraries/rx.complete.md) - complete version of RxJS with all operators, minus the testing operators, and comes with a compat file for older browsers.
+- [`rx.lite.js`](doc/libraries/rx.lite.md) - lite version with event bindings, creation, time and standard query operators with a compat file for older browsers.  For most operations, this is the file you'll want to use unless you want the full power of RxJS.
+- [`rx.lite.extras.js`](doc/libraries/rx.lite.extras.md) - the operators missing from rx.lite.js that can be found in rx.js.
+- [`rx.js`](doc/libraries/rx.md) - core library for ES5 compliant browsers and runtimes plus compatibility for older browsers.
+- [`rx.aggregates.js`](doc/libraries/rx.aggregates.md) - aggregation event processing query operations
+- [`rx.async.js`](doc/libraries/rx.async.md) - async operations such as events, callbacks and promises plus a compat file for older browsers.
+- [`rx.backpressure.js`](doc/libraries/rx.backpressure.md) - backpressure operators such as pause/resume and controlled.
+- [`rx.binding.js`](doc/libraries/rx.binding.md) - binding operators including multicast, publish, publishLast, publishValue, and replay
+- [`rx.coincidence.js`](doc/libraries/rx.coincidence.md) - reactive coincidence join event processing query operations
+- [`rx.experimental.js`](doc/libraries/rx.experimental.md) - experimental operators including imperative operators and forkJoin
+- [`rx.joinpatterns.js`](doc/libraries/rx.joinpatterns.md) - join patterns event processing query operations
+- [`rx.testing.js`](doc/libraries/rx.testing.md) - used to write unit tests for complex event processing queries
+- [`rx.time.js`](doc/libraries/rx.time.md) - time-based event processing query operations
+- [`rx.virtualtime.js`](doc/libraries/rx.virtualtime.md) - virtual-time-based schedulers
+
+## Why RxJS? ##
+
+One question you may ask yourself, is why RxJS?  What about Promises?  Promises are good for solving asynchronous operations such as querying a service with an XMLHttpRequest, where the expected behavior is one value and then completion.  The Reactive Extensions for JavaScript unifies both the world of Promises, callbacks as well as evented data such as DOM Input, Web Workers, Web Sockets.  Once we have unified these concepts, this enables rich composition.
+
+To give you an idea about rich composition, we can create an autocompletion service which takes the user input from a text input and then query a service, making sure not to flood the service with calls for every key stroke, but instead allow to go at a more natural pace.
+
+First, we'll reference the JavaScript files, including jQuery, although RxJS has no dependencies on jQuery...
+```html
+<script src="http://code.jquery.com/jquery.js"></script>
+<script src="rx.lite.js"></script>
+```
+Next, we'll get the user input from an input, listening to the keyup event by using the `Rx.Observable.fromEvent` method.  This will either use the event binding from [jQuery](http://jquery.com), [Zepto](http://zeptojs.com/), [AngularJS](https://angularjs.org/), [Backbone.js](http://backbonejs.org/) and [Ember.js](http://emberjs.com/) if available, and if not, falls back to the native event binding.  This gives you consistent ways of thinking of events depending on your framework, so there are no surprises.
+
+```js
+var $input = $('#input'),
+    $results = $('#results');
+
+/* Only get the value from each key up */
+var keyups = Rx.Observable.fromEvent($input, 'keyup')
+  .map(function (e) {
+    return e.target.value;
+  })
+  .filter(function (text) {
+    return text.length > 2;
+  });
+
+/* Now debounce the input for 500ms */
+var debounced = keyups
+  .debounce(500 /* ms */);
+
+/* Now get only distinct values, so we eliminate the arrows and other control characters */
+var distinct = debounced
+  .distinctUntilChanged();
+```
+
+Now, let's query Wikipedia!  In RxJS, we can instantly bind to any [Promises A+](https://github.com/promises-aplus/promises-spec) implementation through the `Rx.Observable.fromPromise` method or by just directly returning it, and we wrap it for you.
+
+```js
+function searchWikipedia (term) {
+  return $.ajax({
+    url: 'http://en.wikipedia.org/w/api.php',
+    dataType: 'jsonp',
+    data: {
+      action: 'opensearch',
+      format: 'json',
+      search: term
+    }
+  }).promise();
+}
+```
+
+Once that is created, now we can tie together the distinct throttled input and then query the service.  In this case, we'll call `flatMapLatest` to get the value and ensure that we're not introducing any out of order sequence calls.
+
+```js
+var suggestions = distinct
+  .flatMapLatest(searchWikipedia);
+```
+
+Finally, we call the `forEach` method on our observable sequence to start pulling data.
+
+```js
+suggestions.forEach(
+  function (data) {
+    $results
+      .empty()
+      .append ($.map(data[1], function (value) {
+        return $('<li>').text(value);
+      }));
+  },
+  function (error) {
+    $results
+      .empty()
+      .append($('<li>'))
+        .text('Error:' + error);
+  });
+```
+
+And there you have it!

+
+## Getting Started
+
+There are a number of ways to get started with RxJS. The files are available on [cdnjs](http://cdnjs.com/libraries/rxjs/) and [jsDelivr](http://www.jsdelivr.com/#!rxjs).
+
+### Custom Builds
+
+You can use the [`rx-cli`](https://www.npmjs.org/package/rx-cli) to perform custom builds to create the RxJS you want:
+
+```bash
+$ rx --lite --compat --methods select,selectmany,takeuntil,fromevent
+```
+
+### Download the Source
+
+```bash
+git clone https://github.com/Reactive-Extensions/rxjs.git
+cd ./rxjs
+```
+
+### Installing with [NPM](https://npmjs.org/)
+
+```bash`
+$ npm install rx
+$ npm install -g rx
+```
+
+### Using with Node.js and Ringo.js
+
+```js
+var Rx = require('rx');
+```
+
+### Installing with [Bower](http://bower.io/)
+
+```bash
+$ bower install rxjs
+```
+
+### Installing with [Jam](http://jamjs.org/)
+```bash
+$ jam install rx
+```
+### Installing All of RxJS via [NuGet](http://nuget.org/)
+```bash
+$ Install-Package RxJS-All
+```
+### Install individual packages via [NuGet](http://nuget.org/):
+
+    Install-Package RxJS-All
+    Install-Package RxJS-Lite
+    Install-Package RxJS-Main
+    Install-Package RxJS-Aggregates
+    Install-Package RxJS-Async
+    Install-Package RxJS-BackPressure
+    Install-Package RxJS-Binding
+    Install-Package RxJS-Coincidence
+    Install-Package RxJS-Experimental
+    Install-Package RxJS-JoinPatterns
+    Install-Package RxJS-Testing
+    Install-Package RxJS-Time
+
+### In a Browser:
+
+```html
+<!-- Just the core RxJS -->
+<script src="rx.js"></script>
+
+<!-- Or all of RxJS minus testing -->
+<script src="rx.all.js"></script>
+
+<!-- Or keeping it lite -->
+<script src="rx.lite.js"></script>
+```
+
+### Along with a number of our extras for RxJS:
+
+```html
+<script src="rx.aggregates.js"></script>
+<script src="rx.async.js"></script>
+<script src="rx.backpressure.js"></script>
+<script src="rx.binding.js"></script>
+<script src="rx.coincidencejs"></script>
+<script src="rx.experimental.js"></script>
+<script src="rx.joinpatterns.js"></script>
+<script src="rx.time.js"></script>
+<script src="rx.virtualtime.js"></script>
+<script src="rx.testing.js"></script>
+```
+
+### Using RxJS with an AMD loader such as Require.js
+
+```js
+require({
+  'paths': {
+    'rx': 'path/to/rx-lite.js'
+  }
+},
+['rx'], function(Rx) {
+  var obs = Rx.Observable.of(42);
+  obs.forEach(function (x) { console.log(x); });
+});
+```
+
+## What about my libraries? ##
+
+The Reactive Extensions for JavaScript have no external dependencies any library, so they'll work well with just about any library.  We provide bridges and support for various libraries including:
+
+- [React](http://facebook.github.io/react/)
+    - [Rx-React](https://github.com/fdecampredon/rx-react)
+    - [Rx-Flux](https://github.com/fdecampredon/rx-flux)
+- [Ember](http://emberjs.com/)
+    - [RxEmber](https://github.com/blesh/RxEmber)

+RxJS has been thoroughly tested against all major browsers and supports IE6+, Chrome 4+, FireFox 1+, and Node.js v0.4+.
+
+## Contributing ##
+
+There are lots of ways to contribute to the project, and we appreciate our [contributors](https://github.com/Reactive-Extensions/RxJS/wiki/Contributors).  If you wish to contribute, check out our [style guide]((https://github.com/Reactive-Extensions/RxJS/tree/master/doc/contributing)).
+
+You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.

+JS-YAML - YAML 1.2 parser and serializer for JavaScript
+=======================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+[Online Demo](http://nodeca.github.com/js-yaml/)
+
+
+This is an implementation of [YAML](http://yaml.org/), a human friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resourses to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+yaml = require('js-yaml');
+fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  var doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns a JavaScript
+object or throws `YAMLException` on error. By default, does not support regexps,
+functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will throw on warnings if this function is not provided.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, JSON schema is not as strict as defined in the YAML specification.
+It allows numbers in any notaion, use `Null` and `NULL` as `null`, etc.
+Core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources you
+must additionally validate object structure, to avoid injections:
+
+``` javascript
+var untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string, iterator [ , options ])
+
+Same as `safeLoad()`, but understands multi-document sources and apply
+`iterator` to each document.
+
+``` javascript
+var yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string, iterator [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw exception if you try to dump regexps or functions. However, you can
+disable exceptions by `skipInvalid` option.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+
+styles:
+
+``` none
+!!null
+  "canonical"   => "~"
+
+!!int
+  "binary"      => "0b1", "0b101010", "0b1110001111010"
+  "octal"       => "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" => "0x1", "0x2A", "0x1C7A"
+
+!!null, !!bool, !!float
+  "lowercase"   => "null", "true", "false", ".nan", '.inf'
+  "uppercase"   => "NULL", "TRUE", "FALSE", ".NAN", '.INF'
+  "camelcase"   => "Null", "True", "False", ".NaN", '.Inf'
+```
+
+By default, !!int uses `decimal`, and !!null, !!bool, !!float use `lowercase`.
+
+
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS do not allows objects
+or array as keys, and stringifies (by calling .toString method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
+
+
+Breaking changes in 2.x.x -> 3.x.x
+----------------------------------
+
+If your have not used __custom__ tags or loader classes and not loaded yaml
+files via `require()` - no changes needed. Just upgrade library.
+
+In other case, you should:
+
+1. Replace all occurences of `require('xxxx.yml')` by `fs.readFileSync()` +
+  `yaml.safeLoad()`.
+2. rewrite your custom tags constructors and custom loader
+  classes, to conform new API. See
+  [examples](https://github.com/nodeca/js-yaml/tree/master/examples) and
+  [wiki](https://github.com/nodeca/js-yaml/wiki) for details.

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.png?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4
+{ foo: '3', bar: '4' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({paramters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supportied yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument([names or flags], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flags``` - Either a name or a list of option strings, e.g. foo or -f, --foo.
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+# lodash v3.2.0
+
+The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash](https://lodash.com/) exported as [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) modules.
+
+Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
+```bash
+$ lodash modularize modern exports=node -o ./
+$ lodash modern -d -o ./index.js
+```
+
+## Installation
+
+Using npm:
+
+```bash
+$ {sudo -H} npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js/io.js:
+
+```js
+// load the modern build
+var _ = require('lodash');
+// or a method category
+var array = require('lodash/array');
+// or a method
+var chunk = require('lodash/array/chunk');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/3.2.0-npm) for more details.
+
+**Note:**<br>
+Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.<br>
+Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.

+# sprintf.js
+**sprintf.js** is a complete open source JavaScript sprintf implementation for the *browser* and *node.js*.
+
+Its prototype is simple:
+
+    string sprintf(string format , [mixed arg1 [, mixed arg2 [ ,...]]])
+
+The placeholders in the format string are marked by `%` and are followed by one or more of these elements, in this order:
+
+* An optional number followed by a `$` sign that selects which argument index to use for the value. If not specified, arguments will be placed in the same order as the placeholders in the input string.
+* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers.
+* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*.
+* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result.
+* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded.
+* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used on a string, it causes the result to be truncated.
+* A type specifier that can be any of:
+    * `%` — yields a literal `%` character
+    * `b` — yields an integer as a binary number
+    * `c` — yields an integer as the character with that ASCII value
+    * `d` or `i` — yields an integer as a signed decimal number
+    * `e` — yields a float using scientific notation
+    * `u` — yields an integer as an unsigned decimal number
+    * `f` — yields a float as is
+    * `o` — yields an integer as an octal number
+    * `s` — yields a string as is
+    * `x` — yields an integer as a hexadecimal number (lower-case)
+    * `X` — yields an integer as a hexadecimal number (upper-case)
+
+## JavaScript `vsprintf`
+`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments:
+
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])
+
+## Argument swapping
+You can also swap the arguments. That is, the order of the placeholders doesn't have to match the order of the arguments. You can do that by simply indicating in the format string which arguments the placeholders refer to:
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+And, of course, you can repeat the placeholders without having to increase the number of arguments.
+
+## Named arguments
+Format strings may contain replacement fields rather than positional placeholders. Instead of referring to a certain argument, you can now refer to a certain key within an object. Replacement fields are surrounded by rounded parentheses - `(` and `)` - and begin with a keyword that refers to a key:
+
+    var user = {
+        name: "Dolly"
+    }
+    sprintf("Hello %(name)s", user) // Hello Dolly
+Keywords in replacement fields can be optionally followed by any number of keywords or indexes:
+
+    var users = [
+        {name: "Dolly"},
+        {name: "Molly"},
+        {name: "Polly"}
+    ]
+    sprintf("Hello %(users[0].name)s, %(users[1].name)s and %(users[2].name)s", {users: users}) // Hello Dolly, Molly and Polly
+Note: mixing positional and named placeholders is not (yet) supported
+
+## Computed values
+You can pass in a function as a dynamic value and it will be invoked (with no arguments) in order to compute the value on-the-fly.
+
+    sprintf("Current timestamp: %d", Date.now) // Current timestamp: 1398005382890
+    sprintf("Current date and time: %s", function() { return new Date().toString() })
+
+# AngularJS
+You can now use `sprintf` and `vsprintf` (also aliased as `fmt` and `vfmt` respectively) in your AngularJS projects. See `demo/`.
+
+# Installation
+
+## Via Bower
+
+    bower install sprintf
+
+## Or as a node.js module
+
+    npm install sprintf-js
+
+### Usage
+
+    var sprintf = require("sprintf-js").sprintf,
+        vsprintf = require("sprintf-js").vsprintf
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])

+**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](http://en.wikipedia.org/wiki/JavaScript>JavaScript)).
+Esprima is created and maintained by [Ariya Hidayat](http://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/jquery/esprima/contributors).
+
+### Features
+
+- Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](http://esprima.org/doc/index.html#ast) compatible with Mozilla
+[Parser AST](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
+- Optional tracking of syntax node location (index-based and line-column)
+- Heavily tested (> 700 [unit tests](http://esprima.org/test/) with [full code coverage](http://esprima.org/test/coverage.html))
+- [Partial support](http://esprima.org/doc/es6.html) for ECMAScript 6
+
+Esprima serves as a **building block** for some JavaScript
+language tools, from [code instrumentation](http://esprima.org/demo/functiontrace.html)
+to [editor autocompletion](http://esprima.org/demo/autocomplete.html).
+
+Esprima runs on many popular web browsers, as well as other ECMAScript platforms such as
+[Rhino](http://www.mozilla.org/rhino), [Nashorn](http://openjdk.java.net/projects/nashorn/), and [Node.js](https://npmjs.org/package/esprima).
+
+For more information, check the web site [esprima.org](http://esprima.org).

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES6 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) ponyfill
+
+> Ponyfill: A polyfill that doesn't overwrite the native method
+
+
+## Install
+
+```sh
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+var objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, source, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

+# xdg-basedir [![Build Status](https://travis-ci.org/sindresorhus/xdg-basedir.svg?branch=master)](https://travis-ci.org/sindresorhus/xdg-basedir)
+
+> Get [XDG Base Directory](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) paths
+
+
+## Install
+
+```sh
+$ npm install --save xdg-basedir
+```
+
+
+## Usage
+
+```js
+var xdgBasedir = require('xdg-basedir');
+
+xdgBasedir.data;
+//=> /home/sindresorhus/.local/share
+
+xdgBasedir.config;
+//=> /home/sindresorhus/.config
+
+xdgBasedir.dataDirs
+//=> ['/home/sindresorhus/.local/share', '/usr/local/share/', '/usr/share/']
+```
+
+
+## API
+
+The properties `.data`, `.config`, `.cache`, `.runtime` will return `null` in the uncommon case that both the XDG environment variable is not set and the users home directory can't be found. You need to handle this case. A common solution is to [fall back to a temp directory](https://github.com/yeoman/configstore/blob/b82690fc401318ad18dcd7d151a0003a4898a314/index.js#L15).
+
+### .data
+
+Directory for user specific data files.
+
+### .config
+
+Directory for user specific configuration files.
+
+### .cache
+
+Directory for user specific non-essential data files.
+
+### .runtime
+
+Directory for user-specific non-essential runtime files and other file objects (such as sockets, named pipes, etc).
+
+### .dataDirs
+
+Preference-ordered array of base directories to search for data files in addition to `.data`.
+
+### .configDirs
+
+Preference-ordered array of base directories to search for configuration files in addition to `.config`.

+# configstore [![Build Status](https://secure.travis-ci.org/yeoman/configstore.svg?branch=master)](http://travis-ci.org/yeoman/configstore)
+
+> Easily load and persist config without having to think about where and how.
+
+Config is stored in a YAML file to make it simple for users to edit the config directly themselves. The file is located in `$XDG_CONFIG_HOME` or `~/.config`. Eg: `~/.config/configstore/id-of-your-choosing.yml`
+
+
+## Usage
+
+```js
+var Configstore = require('configstore');
+var packageName = require('./package').name;
+
+// Init a Configstore instance with an unique ID eg. package name
+// and optionally some default values
+var conf = new Configstore(packageName, { foo: 'bar' });
+
+conf.set('awesome', true);
+console.log(conf.get('awesome'));  // true
+console.log(conf.get('foo'));      // bar
+
+conf.del('awesome');
+console.log(conf.get('awesome'));  // undefined
+```
+
+
+## Documentation
+
+### Methods
+
+#### .set(key, val)
+
+Set an item
+
+#### .get(key)
+
+Get an item
+
+#### .del(key)
+
+Delete an item
+
+### Properties
+
+#### .all
+
+Get all items as an object or replace the current config with an object:
+
+```js
+conf.all = {
+	hello: 'world'
+};
+```
+
+#### .size
+
+Get the item count
+
+#### .path
+
+Get the path to the config file. Can be used to show the user where the config file is located or even better open it for them.

+
+v0.10.2  --  2014.04.24
+- Simplify and deprecate `isCallable`. It seems in ES5 based engines there are
+  no callable objects which are `typeof obj !== 'function'`
+- Update Array.from map callback signature (up to latest resolution of TC39)
+- Improve documentation
+
+v0.10.1  --  2014.04.14
+Bump version for npm
+(Workaround for accidental premature publish & unpublish of v0.10.0 a while ago)
+
+v0.10.0  --  2014.04.13
+Major update:
+- All methods and function specified for ECMAScript 6 are now introduced as
+  shims accompanied with functions through which (optionally) they can be
+  implementend on native objects
+- Filename convention was changed to shorter and strictly lower case names. e.g.
+  `lib/String/prototype/starts-with` became `string/#/starts-with`
+- Generated functions are guaranteed to have expected length
+- Objects with null prototype (created via `Object.create(null)`) are widely
+  supported (older version have crashed due to implied `obj.hasOwnProperty` and
+  related invocations)
+- Support array subclasses
+- When handling lists do not limit its length to Uint32 range
+- Use newly introduced `Object.eq` for strict equality in place of `Object.is`
+- Iteration of Object have been improved so properties that were hidden or
+  removed after iteration started are not iterated.
+
+Additions:
+- `Array.isPlainArray`
+- `Array.validArray`
+- `Array.prototype.concat` (as updated with ES6)
+- `Array.prototype.copyWithin` (as introduced with ES6)

+- `Object.create` (with fix for V8 issue which disallows prototype turn of
+  objects derived from null

+- `Function.remove`
+- `Function.prototype.silent`
+- `Function.prototype.wrap`

+
+Renames:
+- `Function.i` into `Function.identity`

+- `Number.toUint` into `Number.toPosInteger`
+- `Object.extend` into `Object.assign` (as introduced in ES 6)
+- `Object.extendProperties` into `Object.mixin`, with improved internal
+  handling, so it matches temporarily specified `Object.mixin` for ECMAScript 6
+- `Object.isList` into `Object.isArrayLike`
+- `Object.mapToArray` into `Object.toArray` (with fixed function length)
+- `Object.toPlainObject` into `Object.normalizeOptions` (as this is the real
+  use case where we use this function)
+- `Function.prototype.chain` into `Function.prototype.compose`
+- `Function.prototype.match` into `Function.prototype.spread`
+- `String.prototype.format` into `String.formatMethod`
+
+Improvements & Fixes:
+- Remove workaround for primitive values handling in object iterators
+- `Array.from`: Update so it follows ES 6 spec
+- `Array.prototype.compact`: filters just null and undefined values
+  (not all falsies)
+- `Array.prototype.eIndexOf` and `Array.prototype.eLastIndexOf`: fix position
+  handling, improve internals

+
+v0.9.1  --  2012.09.17
+* Object.reduce - reduce for hash-like collections
+* Accapt any callable object as callback in Object.filter, mapKeys and map
+* Convention cleanup
+
+v0.9.0  --  2012.09.13
+We're getting to real solid API
+
+Removed:
+* Function#memoize - it's grown up to be external package, to be soon published
+  as 'memoizee'
+* String.guid - it doesn't fit es5-ext (extensions) concept, will be provided as
+  external package
+# Function.arguments - obsolete
+# Function.context - obsolete
+# Function#flip - not readable when used, so it was never used
+# Object.clone - obsolete and confusing
+
+Added:
+* String#camelToHyphen - String format convertion
+
+Renamed:
+* String#dashToCamelCase -> String#hyphenToCamel
+
+Fixes:
+* Object.isObject - Quote names in literals that match reserved keywords
+  (older implementations crashed on that)
+* String#repeat - Do not accept negative values (coerce them to 1)
+
+Improvements:
+* Array#remove - Accepts many arguments, we can now remove many values at once
+* Object iterators (forEach, map, some) - Compare function invoked with scope
+  object bound to this
+* Function#curry - Algorithm cleanup
+* Object.isCopy - Support for all types, not just plain objects
+* Object.isPlainObject - Support for cross-frame objects
+* Do not memoize any of the functions, it shouldn't be decided internally
+* Remove Object.freeze calls in reserved, it's not up to convention
+* Improved documentation
+* Better linting (hard-core approach using both JSLint mod and JSHint)
+* Optional arguments are now documented in funtions signature
+
+v0.8.2  --  2012.06.22
+Fix errors in Array's intersection and exclusion methods, related to improper
+usage of contains method
+
+v0.8.1  --  2012.06.13
+Reorganized internal logic of Function.prototype.memoize. So it's more safe now
+and clears cache properly. Additionally preventCache option was provided.
+
+v0.8.0  --  2012.05.28
+Again, major overhaul. Probably last experimental stuff was trashed, all API
+looks more like standard extensions now.
+
+Changes:
+* Turn all Object.prototype extensions into functions and move them to Object
+namespace. We learned that extending Object.prototype is bad idea in any case.
+* Rename Function.prototype.curry into Function.prototype.partial. This function
+  is really doing partial application while currying is slightly different
+  concept.
+* Convert Function.prototype.ncurry to new implementation of
+  Function.prototype.curry, it now serves real curry concept additionaly it
+  covers use cases for aritize and hold, which were removed.
+* Rename Array's peek to last, and provide support for sparse arrays in it
+* Rename Date's monthDaysCount into daysInMonth
+* Simplify object iterators, now order of iteration can be configured with just
+  compareFn argument (no extra byKeys option)
+* Rename Object.isDuplicate to Object.isCopy
+* Rename Object.isEqual to Object.is which is compatible with future 'is'
+  keyword
+* Function.memoize is now Function.prototype.memoize. Additionally clear cache
+  functionality is added, and access to original arguments object.
+* Rename validation functions: assertNotNull to validValue, assertCallable to
+  validCallable. validValue was moved to Object namespace. On success they now
+  return validated value instead of true, it supports better composition.
+  Additionally created Date.validDate and Error.validError
+* All documentation is now held in README.md not in code files.
+* Move guid to String namespace. All guids now start with numbers.
+* Array.generate: fill argument is now optional
+* Object.toArray is now Array.from (as new ES6 specification draft suggests)
+* All methods that rely on indexOf or lastIndexOf, now rely on egal (Object.is)
+  versions of them (eIndexOf, eLastIndexOf)
+* Turn all get* functions that returned methods into actuall methods (get*
+  functionality can still be achieved with help of Function.prototype.partial).
+  So: Date.getFormat is now Date.prototype.format,
+  Number.getPad is now Number.prototype.pad,
+  String.getFormat is now String.prototype.format,
+  String.getIndent is now String.prototype.indent,
+  String.getPad is now String.prototype.pad
+* Refactored Object.descriptor, it is now just two functions, main one and
+  main.gs, main is for describing values, and gs for describing getters and
+  setters. Configuration is passed with first argument as string e.g. 'ce' for
+  configurable and enumerable. If no configuration string is provided then by
+  default it returns configurable and writable but not enumerable for value or
+  configurable but not enumerable for getter/setter
+* Function.prototype.silent now returns prepared function (it was
+  expected to be fixed for 0.7)
+* Reserved keywords map (reserved) is now array not hash.
+* Object.merge is now Object.extend (while former Object.extend was completely
+  removed) - 'extend' implies that we change object, not creating new one (as
+  'merge' may imply). Similarily Object.mergeProperties was renamed to
+  Object.extendProperties
+* Position argument support in Array.prototype.contains and
+  String.prototype.contains (so it follows ES6 specification draft)
+* endPosition argument support in String.prototype.endsWith and fromPosition
+  argument support in String.prototype.startsWith (so it follows ES6
+  specification draft)
+* Better and cleaner String.prototype.indent implementation. No default value
+  for indent string argument, optional nest value (defaults to 1), remove
+  nostart argument
+* Correct length values for most methods (so they reflect length of similar
+  methods in standard)
+* Length argument is now optional in number and string pad methods.
+* Improve arguments validation in general, so it adheres to standard conventions
+* Fixed format of package.json
+
+Removed methods and functions:
+* Object.prototype.slice - Object is not ordered collection, so slice doesn't
+  make sense.
+* Function's rcurry, rncurry, s - too cumbersome for JS, not many use cases for
+  that
+* Function.prototype.aritize and Function.prototype.hold - same functionality
+  can be achieved with new Function.prototype.curry
+* Function.prototype.log - provided more generic Function.prototype.wrap for
+  same use case
+* getNextIdGenerator - no use case for that (String.guid should be used if
+  needed)
+* Object.toObject - Can be now acheived with Object(validValue(x))
+* Array.prototype.someValue - no real use case (personally used once and
+  case was already controversial)
+* Date.prototype.duration - moved to external package
+* Number.getAutoincrement - No real use case
+* Object.prototype.extend, Object.prototype.override,
+  Object.prototype.plainCreate, Object.prototype.plainExtend - It was probably
+  too complex, same should be achieved just with Object.create,
+  Object.descriptor and by saving references to super methods in local scope.
+* Object.getCompareBy - Functions should be created individually for each use
+  case
+* Object.get, Object.getSet, Object.set, Object.unset - Not many use cases and
+  same can be easily achieved with simple inline function
+* String.getPrefixWith - Not real use case for something that can be easily
+  achieved with '+' operator
+* Object.isPrimitive - It's just negation of Object.isObject
+* Number.prototype.isLess, Number.prototype.isLessOrEqual - they shouldn't be in
+  Number namespace and should rather be addressed with simple inline functions.
+* Number.prototype.subtract - Should rather be addressed with simple inline
+  function
+
+New methods and functions:
+* Array.prototype.lastIndex - Returns last declared index in array
+* String.prototype.last - last for strings
+* Function.prototype.wrap - Wrap function with other, it allows to specify
+  before and after behavior transform return value or prevent original function
+  from being called.
+* Math.sign - Returns sign of a number (already in ES6 specification draft)
+* Number.toInt - Converts value to integer (already in ES6 specification draft)
+* Number.isNaN - Returns true if value is NaN (already in ES6 specification
+  draft)
+* Number.toUint - Converts value to unsigned integer
+* Number.toUint32 - Converts value to 32bit unsigned integer
+* Array.prototype.eIndexOf, eLastIndexOf - Egal version (that uses Object.is) of
+  standard methods (all methods that were using native indexOf or lastIndexOf
+  now uses eIndexOf and elastIndexOf respectively)
+* Array.of - as it's specified for ES6
+
+Fixes:
+* Fixed binarySearch so it always returns valid list index
+* Object.isList - it failed on lists that are callable (e.g. NodeList in Nitro
+  engine)
+* Object.map now supports third argument for callback
+
+v0.7.1  --  2012.01.05
+New methods:
+* Array.prototype.firstIndex - returns first valid index of array (for
+	sparse arrays it may not be '0'
+
+Improvements:
+* Array.prototype.first - now returns value for index returned by firstIndex
+* Object.prototype.mapToArray - can be called without callback, then array of
+	key-value pairs is returned
+
+Fixes
+* Array.prototype.forEachRight, object's length read through UInt32 conversion
+
+v0.7.0  --  2011.12.27
+Major update.
+Stepped back from experimental ideas and introduced more standard approach
+taking example from how ES5 methods and functions are designed. One exceptions
+is that, we don’t refrain from declaring methods for Object.prototype - it’s up
+to developer whether how he decides to use it in his context (as function or as
+method).
+
+In general:
+* Removed any method 'functionalization' and functionalize method itself.
+	es5-ext declares plain methods, which can be configured to work as functions
+	with call.bind(method) - see documentation.
+* Removed separation of Object methods for ES5 (with descriptors) and
+	ES3 (plain) - we're following ES5 idea on that, some methods are intended just
+	for enumerable properties and some are for all properties, all are declared
+	for Object.prototype
+* Removed separation of Array generic (collected in List folder) and not generic
+	methods (collected in Array folder). Now all methods are generic and are in
+	Array/prototype folder. This separation also meant, that methods in Array are
+	usually destructive. We don’t do that separation now, there’s generally no use
+	case for destructive iterators, we should be fine with one version of each
+	method, (same as ES5 is fine with  e.g. one, non destructive 'filter' method)
+* Folder structure resembles tree of native ES5 Objects
+* All methods are written with ES5 conventions in mind, it means that most
+	methods are generic and can be run on any object. In more detail:
+	** Array.prototype and Object.prototype methods can be run on any object (any
+		not null or undefined value),
+	** Date.prototype methods should be called only on Date instances.
+	** Function.prototype methods can be called on any callable objects (not
+		necessarily functions)
+	** Number.prototype & String.prototype methods can be called on any value, in
+		case of Number it it’ll be degraded to number, in case of string it’ll be
+		degraded to string.
+* Travis CI support (only for Node v0.6 branch, as v0.4 has buggy V8 version)
+
+Improvements for existing functions and methods:
+* Function.memoize (was Function.cache) is now fully generic, can operate on any
+	type of arguments and it’s NaN safe (all NaN objects are considered equal)
+* Method properties passed to Object.prototype.extend or
+	Object.prototype.override can aside of _super optionally take prototype object
+	via _proto argument
+* Object iterators: forEach, mapToArray and every can now iterate in specified
+	order
+* pluck, invoke and other functions that return reusable functions or methods
+	have now their results memoized.
+
+New methods:
+* Global: assertNotNull, getNextIdGenerator, guid, isEqual, isPrimitive,
+	toObject
+* Array: generate
+* Array.prototype: binarySearch, clear, contains, diff, exclusion, find, first,
+	forEachRight, group, indexesOf, intersection, remove, someRight, someValue
+* Boolean: isBoolean
+* Date: isDate
+* Function: arguments, context, insert, isArguments, remove
+* Function.prototype: not, silent
+* Number: getAutoincrement, isNumber
+* Number.prototype: isLessOrEqual, isLess, subtract
+* Object: assertCallable, descriptor (functions for clean descriptors),
+	getCompareBy, isCallable, isObject
+* Object.prototype: clone (real clone), compact, count, diff, empty,
+	getPropertyNames, get, keyOf, mapKeys, override, plainCreate, plainExtend,
+	slice, some, unset
+* RegExp: isRegExp
+* String: getPrefixWith, isString
+* String.prototype: caseInsensitiveCompare, contains, isNumeric
+

+# es5-ext
+## ECMAScript 5 extensions
+### (with respect to ECMAScript 6 standard)
+
+Shims for upcoming ES6 standard and other goodies implemented strictly with ECMAScript conventions in mind.
+
+It's designed to be used in compliant ECMAScript 5 or ECMAScript 6 environments. Older environments are not supported, although most of the features should work with correct ECMAScript 5 shim on board.
+
+When used in ECMAScript 6 environment, native implementation (if valid) takes precedence over shims.
+
+### Installation
+
+	$ npm install es5-ext
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+#### ECMAScript 6 features
+
+You can force ES6 features to be implemented in your environment, e.g. following will assign `from` function to `Array` (only if it's not implemented already).
+
+```javascript
+require('es5-ext/array/from/implement');
+Array.from('foo'); // ['f', 'o', 'o']
+```
+
+You can also access shims directly, without fixing native objects. Following will return native `Array.from` if it's available and fallback to shim if it's not.
+
+```javascript
+var aFrom = require('es5-ext/array/from');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+If you want to use shim unconditionally (even if native implementation exists) do:
+
+```javascript
+var aFrom = require('es5-ext/array/from/shim');
+aFrom('foo'); // ['f', 'o', 'o']
+```
+
+##### List of ES6 shims
+
+It's about properties introduced with ES6 and those that have been updated in new spec.

+#### Non ECMAScript standard features
+
+__es5-ext__ provides also other utils, and implements them as if they were proposed for a standard. It mostly offers methods (not functions) which can directly be assigned to native prototypes:
+
+```javascript
+Object.defineProperty(Function.prototype, 'partial', { value: require('es5-ext/function/#/partial'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(Array.prototype, 'flatten', { value: require('es5-ext/array/#/flatten'),
+  configurable: true, enumerable: false, writable: true });
+Object.defineProperty(String.prototype, 'capitalize', { value: require('es5-ext/string/#/capitalize'),
+  configurable: true, enumerable: false, writable: true });
+```
+
+See [es5-extend](https://github.com/wookieb/es5-extend#es5-extend), a great utility that automatically will extend natives for you. 
+
+__Important:__ Remember to __not__ extend natives in scope of generic reusable packages (e.g. ones you intend to publish to npm). Extending natives is fine __only__ if you're the _owner_ of the global scope, so e.g. in final project you lead development of.
+
+When you're in situation when native extensions are not good idea, then you should use methods indirectly:
+
+
+```javascript
+var flatten = require('es5-ext/array/#/flatten');
+
+flatten.call([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+for better convenience you can turn methods into functions:
+
+
+```javascript
+var call = Function.prototype.call
+var flatten = call.bind(require('es5-ext/array/#/flatten'));
+
+flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+You can configure custom toolkit (like [underscorejs](http://underscorejs.org/)), and use it throughout your application
+
+```javascript
+var util = {};
+util.partial = call.bind(require('es5-ext/function/#/partial'));
+util.flatten = call.bind(require('es5-ext/array/#/flatten'));
+util.startsWith = call.bind(require('es5-ext/string/#/starts-with'));
+
+util.flatten([1, [2, [3, 4]]]); // [1, 2, 3, 4]
+```
+
+As with native ones most methods are generic and can be run on any type of object.

+
+`Object.create` alternative that provides workaround for [V8 issue](http://code.google.com/p/v8/issues/detail?id=2804).
+
+When `null` is provided as a prototype, it's substituted with specially prepared object that derives from Object.prototype but has all Object.prototype properties shadowed with undefined.
+
+It's quirky solution that allows us to have plain objects with no truthy properties but with turnable prototype.
+
+Use only for objects that you plan to switch prototypes of and be aware of limitations of this workaround.

+
+Analogous to Array.prototype.forEach. Calls a function for each key-value pair found in object

+
+#### keyOf(obj, searchValue) _(es5-ext/object/key-of)_

+
+#### keys(obj) _(es5-ext/object/keys)_
+

+
+Useful for functions in which we either need to keep options object for future reference or need to modify it for internal use.

+- `options` can be undefined in such case empty plain object is returned.
+- Copies all enumerable properties found down prototype chain.

+
+#### unserialize(str) _(es5-ext/object/unserialize)_
+
+Userializes value previously serialized with [serialize](#serializevalue-es5-extobjectserialize)

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)
+
+	$ npm test

+# es6-iterator
+## ECMAScript 6 Iterator interface
+
+### Installation
+
+	$ npm install es6-iterator
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## API
+
+### Constructors
+
+#### Iterator(list) _(es6-iterator)_
+
+Abstract Iterator interface. Meant for extensions and not to be used on its own.
+
+Accepts any _list_ object (technically object with numeric _length_ property).
+
+_Mind it doesn't iterate strings properly, for that use dedicated [StringIterator](#string-iterator)_
+
+```javascript
+var Iterator = require('es6-iterator')
+var iterator = new Iterator([1, 2, 3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+
+#### ArrayIterator(arrayLike[, kind]) _(es6-iterator/array)_
+
+Dedicated for arrays and array-likes. Supports three iteration kinds:
+* __value__ _(default)_ - Iterates values
+* __key__ - Iterates indexes
+* __key+value__ - Iterates keys and indexes, each iteration value is in _[key, value]_ form.
+
+
+```javascript
+var ArrayIterator = require('es6-iterator/array')
+var iterator = new ArrayIterator([1, 2, 3], 'key+value');
+
+iterator.next(); // { value: [0, 1], done: false }
+iterator.next(); // { value: [1, 2], done: false }
+iterator.next(); // { value: [2, 3], done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+May also be used for _arguments_ objects:
+
+```javascript
+(function () {
+  var iterator = new ArrayIterator(arguments);
+
+  iterator.next(); // { value: 1, done: false }
+  iterator.next(); // { value: 2, done: false }
+  iterator.next(); // { value: 3, done: false }
+  iterator.next(); // { value: undefined, done: true }
+}(1, 2, 3));
+```
+
+#### StringIterator(str) _(es6-iterator/string)_
+
+Assures proper iteration over unicode symbols.  
+See: http://mathiasbynens.be/notes/javascript-unicode
+
+```javascript
+var StringIterator = require('es6-iterator/string');
+var iterator = new StringIterator('f🙈o🙉o🙊');
+
+iterator.next(); // { value: 'f', done: false }
+iterator.next(); // { value: '🙈', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙉', done: false }
+iterator.next(); // { value: 'o', done: false }
+iterator.next(); // { value: '🙊', done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+### Function utilities
+
+#### forOf(iterable, callback[, thisArg]) _(es6-iterator/for-of)_
+
+Polyfill for ECMAScript 6 [`for...of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of) statement.
+
+```
+var forOf = require('es6-iterator/for-of');
+var result = [];
+
+forOf('🙈🙉🙊', function (monkey) { result.push(monkey); });
+console.log(result); // ['🙈', '🙉', '🙊'];
+```
+
+Optionally you can break iteration at any point:
+
+```javascript
+var result = [];
+
+forOf([1,2,3,4]', function (val, doBreak) {
+  result.push(monkey);
+  if (val >= 3) doBreak();
+});
+console.log(result); // [1, 2, 3];
+```
+
+#### get(obj) _(es6-iterator/get)_
+
+Return iterator for any iterable object.
+
+```javascript
+var getIterator = require('es6-iterator/get');
+var iterator = get([1,2,3]);
+
+iterator.next(); // { value: 1, done: false }
+iterator.next(); // { value: 2, done: false }
+iterator.next(); // { value: 3, done: false }
+iterator.next(); // { value: undefined, done: true }
+```
+
+#### isIterable(obj) _(es6-iterator/is-iterable)_
+
+Whether _obj_ is iterable
+
+```javascript
+var isIterable = require('es6-iterator/is-iterable');
+
+isIterable(null); // false
+isIterable(true); // false
+isIterable('str'); // true
+isIterable(['a', 'r', 'r']); // true
+isIterable(new ArrayIterator([])); // true
+```
+
+#### validIterable(obj) _(es6-iterator/valid-iterable)_
+
+If _obj_ is an iterable it is returned. Otherwise _TypeError_ is thrown.
+
+### Method extensions
+
+#### iterator.chain(iterator1[, …iteratorn]) _(es6-iterator/#/chain)_
+
+Chain multiple iterators into one.
+

+# es6-symbol
+## ECMAScript 6 Symbol polyfill
+
+For more information about symbols see following links
+- [Symbols in ECMAScript 6 by Axel Rauschmayer](http://www.2ality.com/2014/12/es6-symbols.html)
+- [MDN Documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol)
+- [Specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-constructor)
+
+### Limitations
+
+Underneath it uses real string property names which can easily be retrieved, however accidental collision with other property names is unlikely.
+
+### Usage
+
+If you'd like to use native version when it exists and fallback to polyfill if it doesn't (but without implementing `Symbol` on global scope), do:
+
+```javascript
+var Symbol = require('es6-symbol');
+```
+
+If you want to make sure your environment implements `Symbol`, do:
+
+```javascript
+require('es6-symbol/implement');
+```
+
+If you strictly want to use polyfill even if native `Symbol` exists (hard to find a good reason for that), do:
+
+```javascript
+var Symbol = require('es6-symbol/polyfill');
+```
+
+#### API
+
+Best is to refer to [specification](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-symbol-objects). Still if you want quick look, follow examples:
+
+```javascript
+var Symbol = require('es6-symbol');
+
+var symbol = Symbol('My custom symbol');
+var x = {};
+
+x[symbol] = 'foo';
+console.log(x[symbol]); 'foo'
+
+// Detect iterable:
+var iterator, result;
+if (possiblyIterable[Symbol.iterator]) {
+  iterator = possiblyIterable[Symbol.iterator]();
+  result = iterator.next();
+  while(!result.done) {
+    console.log(result.value);
+    result = iterator.next();
+  }
+}
+```
+
+### Installation
+#### NPM
+
+In your project path:
+
+	$ npm install es6-symbol
+
+##### Browser
+
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+## Tests [![Build Status](https://travis-ci.org/medikoo/es6-symbol.png)](https://travis-ci.org/medikoo/es6-symbol)

+* Removed support for optional "emitter" argument in `emit` method, it was
+  cumbersome to use, and should be solved just with event objects
+
+v0.1.5  --  2012.08.06
+* (maintanance) Do not use descriptors for internal objects, it exposes V8 bugs
+  (only Node v0.6 branch)
+
+v0.1.4  --  2012.06.13
+* Fix detachment of listeners added with 'once'
+
+v0.1.3  --  2012.05.28
+* Updated es5-ext to latest version (v0.8)
+* Cleared package.json so it's in npm friendly format
+
+v0.1.2  --  2012.01.22
+* Support for emitter argument in emit function, this allows some listeners not
+  to be notified about event
+* allOff - removes all listeners from object
+* All methods returns self object
+* Internal fixes
+* Travis CI integration
+
+v0.1.1  --  2011.08.08
+* Added TAD test suite to devDependencies, configured test commands.
+  Tests can be run with 'make test' or 'npm test'
+
+v0.1.0  --  2011.08.08
+Initial version

+# event-emitter
+## Environment agnostic event emitter
+
+### Installation
+
+	$ npm install event-emitter
+	
+To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: [Browserify](http://browserify.org/), [Webmake](https://github.com/medikoo/modules-webmake) or [Webpack](http://webpack.github.io/)
+
+### Usage
+
+```javascript
+var ee = require('event-emitter');
+
+var emitter = ee({}), listener;
+
+emitter.on('test', listener = function (args) {
+  // …emitter logic
+});
+
+emitter.once('test', function (args) {
+  // …invoked only once(!)
+});
+
+emitter.emit('test', arg1, arg2/*…args*/); // Two above listeners invoked
+emitter.emit('test', arg1, arg2/*…args*/); // Only first listener invoked
+
+emitter.off('test', listener);              // Removed first listener
+emitter.emit('test', arg1, arg2/*…args*/); // No listeners invoked
+```
+### Additional utilities
+
+#### allOff(obj) _(event-emitter/all-off)_
+
+Removes all listeners from given event emitter object
+
+#### hasListeners(obj[, name]) _(event-emitter/has-listeners)_
+
+Whether object has some listeners attached to the object.
+When `name` is provided, it checks listeners for specific event name
+
+```javascript
+var emitter = ee();
+var hasListeners = require('event-emitter/has-listeners');
+var listener = function () {};
+
+hasListeners(emitter); // false
+
+emitter.on('foo', listener);
+hasListeners(emitter); // true
+hasListeners(emitter, 'foo'); // true
+hasListeners(emitter, 'bar'); // false
+
+emitter.off('foo', listener);
+hasListeners(emitter, 'foo'); // false
+```
+
+#### pipe(source, target[, emitMethodName]) _(event-emitter/pipe)_
+
+Pipes all events from _source_ emitter onto _target_ emitter (all events from _source_ emitter will be emitted also on _target_ emitter, but not other way).  
+Returns _pipe_ object which exposes `pipe.close` function. Invoke it to close configured _pipe_.  
+It works internally by redefinition of `emit` method, if in your interface this method is referenced differently, provide its name (or symbol) with third argument.
+
+#### unify(emitter1, emitter2) _(event-emitter/unify)_
+
+Unifies event handling for two objects. Events emitted on _emitter1_ would be also emitter on _emitter2_, and other way back.  
+Non reversible.
+
+```javascript
+var eeUnify = require('event-emitter/unify');
+
+var emitter1 = ee(), listener1, listener3;
+var emitter2 = ee(), listener2, listener4;
+
+emitter1.on('test', listener1 = function () { });
+emitter2.on('test', listener2 = function () { });
+
+emitter1.emit('test'); // Invoked listener1
+emitter2.emit('test'); // Invoked listener2
+
+var unify = eeUnify(emitter1, emitter2);
+
+emitter1.emit('test'); // Invoked listener1 and listener2
+emitter2.emit('test'); // Invoked listener1 and listener2
+
+emitter1.on('test', listener3 = function () { });
+emitter2.on('test', listener4 = function () { });
+
+emitter1.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+emitter2.emit('test'); // Invoked listener1, listener2, listener3 and listener4
+```

(So you can show `****` instead of the\n  password, for example.)\n\n* `prompt` If you are using a replacement char, and also using a\n  prompt with a readline stream (as for a `Password: *****` input),\n  then specify what the prompt is so that backspace will work\n  properly.  Otherwise, pressing backspace will overwrite the prompt\n  with the replacement character, which is weird.\n\n## ms.mute()\n\nSet `muted` to `true`.  Turns `.write()` into a no-op.\n\n## ms.unmute()\n\nSet `muted` to `false`\n\n## ms.isTTY\n\nTrue if the pipe destination is a TTY, or if the incoming pipe source is\na TTY.\n\n## Other stream methods...\n\nThe other standard readable and writable stream methods are all\navailable.  The MuteStream object acts as a facade to its pipe source\nand destination.\n",

+readline2 [![Build Status](https://travis-ci.org/SBoudrias/readline2.png?branch=master)](https://travis-ci.org/SBoudrias/readline2)
+=========
+
+Node.js (v0.8 and v0.10) had some bugs and issues with the default [Readline](http://nodejs.org/api/readline.html) module.
+
+This module include fixes seen in later version (0.11) and ease some undesirable behavior one could see using the readline to create interatives prompts. This means `readline2` change some behaviors and as so is **not** meant to be a drop-in replacement.
+
+This project is extracted from the core of [Inquirer.js interactive prompt interface](https://github.com/SBoudrias/Inquirer.js) to be available as a standalone module.
+
+
+Documentation
+-------------
+
+**Installation**: `npm install --save readline2`
+
+### readline2.createInterface( options ); -> {Interface}
+
+Present the same API as [Node.js `readline.createInterface()`](http://nodejs.org/api/readline.html)
+
+#### Improvements
+- Default `options.input` as `process.stdin`
+- Default `options.output` as `process.stdout`
+- `interface.stdout` is wrapped in a [MuteStream](https://github.com/isaacs/mute-stream)
+- Prevent `up` and `down` keys from moving through history inside the readline
+- Fix cursor position after a line refresh when the `Interface` prompt contains ANSI colors

+
+
+## Usage
+
+```js
+var ansiRegex = require('ansi-regex');
+

+```
+
+*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

+# The Reactive Extensions for JavaScript (RxJS) <sup>2.3</sup>... #
+*...is a set of libraries to compose asynchronous and event-based programs using observable collections and [Array#extras](http://blogs.msdn.com/b/ie/archive/2010/12/13/ecmascript-5-part-2-array-extras.aspx) style composition in JavaScript*
+
+The project is actively developed by [Microsoft Open Technologies, Inc.](http://msopentech.com/), in collaboration with a community of open source developers.
+
+## The Need to go Reactive ##
+
+Applications, especially on the web have changed over the years from being a simple static page, to DHTML with animations, to the Ajax revolution.  Each time, we're adding more complexity, more data, and asynchronous behavior to our applications.  How do we manage it all?  How do we scale it?  By moving towards "Reactive Architectures" which are event-driven, resilient and responsive.  With the Reactive Extensions, you have all the tools you need to help build these systems.
+
+## About the Reactive Extensions ##
+
+The Reactive Extensions for JavaScript (RxJS) is a set of libraries for composing asynchronous and event-based programs using observable sequences and fluent query operators that many of you already know by [Array#extras](http://blogs.msdn.com/b/ie/archive/2010/12/13/ecmascript-5-part-2-array-extras.aspx) in JavaScript. Using RxJS, developers represent asynchronous data streams with Observables, query asynchronous data streams using our many operators, and parameterize the concurrency in the asynchronous data streams using Schedulers. Simply put, RxJS = Observables + Operators + Schedulers.
+
+Whether you are authoring a web-based application in JavaScript or a server-side application in Node.js, you have to deal with asynchronous and event-based programming as a matter of course. Although some patterns are emerging such as the Promise pattern, handling exceptions, cancellation, and synchronization is difficult and error-prone.
+
+Using RxJS, you can represent multiple asynchronous data streams (that come from diverse sources, e.g., stock quote, tweets, computer events, web service requests, etc.), and subscribe to the event stream using the Observer object. The Observable notifies the subscribed Observer instance whenever an event occurs.
+
+Because observable sequences are data streams, you can query them using standard query operators implemented by the Observable type. Thus you can filter, project, aggregate, compose and perform time-based operations on multiple events easily by using these operators. In addition, there are a number of other reactive stream specific operators that allow powerful queries to be written. Cancellation, exceptions, and synchronization are also handled gracefully by using the methods on the Observable object.
+
+But the best news of all is that you already know how to program like this.  Take for example the following JavaScript code, where we get some stock data and then manipulate and then iterate the results.
+
+```js
+/* Get stock data somehow */
+var source = getStockData();
+
+source
+  .filter(function (quote) {
+      return quote.price > 30;
+  })
+  .map(function (quote) {
+      return quote.price;
+  })
+  .forEach(function (price) {
+    console.log('Prices higher than $30: $' + price);
+  });
+```
+
+Now what if this data were to come as some sort of event, for example a stream, such as as a WebSocket, then we could pretty much write the same query to iterate our data, with very little change.
+
+```js
+/* Get stock data somehow */
+var source = getAsyncStockData();
+
+var subscription = source
+  .filter(function (quote) {
+    return quote.price > 30;
+  })
+  .map(function (quote) {
+    return quote.price;
+  })
+  .forEach(
+    function (price) {
+      console.log('Prices higher than $30: $' + price);
+    },
+    function (err) {
+      console.log('Something went wrong: ' + err.message);
+    });
+
+/* When we're done */
+subscription.dispose();
+```
+
+The only difference is that we can handle the errors inline with our subscription.  And when we're no longer interested in receiving the data as it comes streaming in, we call `dispose` on our subscription.
+
+## Batteries Included ##
+
+Sure, there are a lot of libraries to get started with RxJS?  Confused on where to get started?  Start out with the complete set of operators with [`rx.all.js`](doc/libraries/rx.complete.md), then you can reduce it to the number of operators that you really need, and perhaps stick with something as small as [`rx.lite.js`](doc/libraries/rx.lite.md).
+
+This set of libraries include:
+
+- [`rx.all.js`](doc/libraries/rx.complete.md) - complete version of RxJS with all operators, minus the testing operators, and comes with a compat file for older browsers.
+- [`rx.lite.js`](doc/libraries/rx.lite.md) - lite version with event bindings, creation, time and standard query operators with a compat file for older browsers.  For most operations, this is the file you'll want to use unless you want the full power of RxJS.
+- [`rx.lite.extras.js`](doc/libraries/rx.lite.extras.md) - the operators missing from rx.lite.js that can be found in rx.js.
+- [`rx.js`](doc/libraries/rx.md) - core library for ES5 compliant browsers and runtimes plus compatibility for older browsers.
+- [`rx.aggregates.js`](doc/libraries/rx.aggregates.md) - aggregation event processing query operations
+- [`rx.async.js`](doc/libraries/rx.async.md) - async operations such as events, callbacks and promises plus a compat file for older browsers.
+- [`rx.backpressure.js`](doc/libraries/rx.backpressure.md) - backpressure operators such as pause/resume and controlled.
+- [`rx.binding.js`](doc/libraries/rx.binding.md) - binding operators including multicast, publish, publishLast, publishValue, and replay
+- [`rx.coincidence.js`](doc/libraries/rx.coincidence.md) - reactive coincidence join event processing query operations
+- [`rx.experimental.js`](doc/libraries/rx.experimental.md) - experimental operators including imperative operators and forkJoin
+- [`rx.joinpatterns.js`](doc/libraries/rx.joinpatterns.md) - join patterns event processing query operations
+- [`rx.testing.js`](doc/libraries/rx.testing.md) - used to write unit tests for complex event processing queries
+- [`rx.time.js`](doc/libraries/rx.time.md) - time-based event processing query operations
+- [`rx.virtualtime.js`](doc/libraries/rx.virtualtime.md) - virtual-time-based schedulers
+
+## Why RxJS? ##
+
+One question you may ask yourself, is why RxJS?  What about Promises?  Promises are good for solving asynchronous operations such as querying a service with an XMLHttpRequest, where the expected behavior is one value and then completion.  The Reactive Extensions for JavaScript unifies both the world of Promises, callbacks as well as evented data such as DOM Input, Web Workers, Web Sockets.  Once we have unified these concepts, this enables rich composition.
+
+To give you an idea about rich composition, we can create an autocompletion service which takes the user input from a text input and then query a service, making sure not to flood the service with calls for every key stroke, but instead allow to go at a more natural pace.
+
+First, we'll reference the JavaScript files, including jQuery, although RxJS has no dependencies on jQuery...
+```html
+<script src="http://code.jquery.com/jquery.js"></script>
+<script src="rx.lite.js"></script>
+```
+Next, we'll get the user input from an input, listening to the keyup event by using the `Rx.Observable.fromEvent` method.  This will either use the event binding from [jQuery](http://jquery.com), [Zepto](http://zeptojs.com/), [AngularJS](https://angularjs.org/), [Backbone.js](http://backbonejs.org/) and [Ember.js](http://emberjs.com/) if available, and if not, falls back to the native event binding.  This gives you consistent ways of thinking of events depending on your framework, so there are no surprises.
+
+```js
+var $input = $('#input'),
+    $results = $('#results');
+
+/* Only get the value from each key up */
+var keyups = Rx.Observable.fromEvent($input, 'keyup')
+  .map(function (e) {
+    return e.target.value;
+  })
+  .filter(function (text) {
+    return text.length > 2;
+  });
+
+/* Now debounce the input for 500ms */
+var debounced = keyups
+  .debounce(500 /* ms */);
+
+/* Now get only distinct values, so we eliminate the arrows and other control characters */
+var distinct = debounced
+  .distinctUntilChanged();
+```
+
+Now, let's query Wikipedia!  In RxJS, we can instantly bind to any [Promises A+](https://github.com/promises-aplus/promises-spec) implementation through the `Rx.Observable.fromPromise` method or by just directly returning it, and we wrap it for you.
+
+```js
+function searchWikipedia (term) {
+  return $.ajax({
+    url: 'http://en.wikipedia.org/w/api.php',
+    dataType: 'jsonp',
+    data: {
+      action: 'opensearch',
+      format: 'json',
+      search: term
+    }
+  }).promise();
+}
+```
+
+Once that is created, now we can tie together the distinct throttled input and then query the service.  In this case, we'll call `flatMapLatest` to get the value and ensure that we're not introducing any out of order sequence calls.
+
+```js
+var suggestions = distinct
+  .flatMapLatest(searchWikipedia);
+```
+
+Finally, we call the `forEach` method on our observable sequence to start pulling data.
+
+```js
+suggestions.forEach(
+  function (data) {
+    $results
+      .empty()
+      .append ($.map(data[1], function (value) {
+        return $('<li>').text(value);
+      }));
+  },
+  function (error) {
+    $results
+      .empty()
+      .append($('<li>'))
+        .text('Error:' + error);
+  });
+```
+
+And there you have it!

+
+## Getting Started
+
+There are a number of ways to get started with RxJS. The files are available on [cdnjs](http://cdnjs.com/libraries/rxjs/) and [jsDelivr](http://www.jsdelivr.com/#!rxjs).
+
+### Custom Builds
+
+You can use the [`rx-cli`](https://www.npmjs.org/package/rx-cli) to perform custom builds to create the RxJS you want:
+
+```bash
+$ rx --lite --compat --methods select,selectmany,takeuntil,fromevent
+```
+
+### Download the Source
+
+```bash
+git clone https://github.com/Reactive-Extensions/rxjs.git
+cd ./rxjs
+```
+
+### Installing with [NPM](https://npmjs.org/)
+
+```bash`
+$ npm install rx
+$ npm install -g rx
+```
+
+### Using with Node.js and Ringo.js
+
+```js
+var Rx = require('rx');
+```
+
+### Installing with [Bower](http://bower.io/)
+
+```bash
+$ bower install rxjs
+```
+
+### Installing with [Jam](http://jamjs.org/)
+```bash
+$ jam install rx
+```
+### Installing All of RxJS via [NuGet](http://nuget.org/)
+```bash
+$ Install-Package RxJS-All
+```
+### Install individual packages via [NuGet](http://nuget.org/):
+
+    Install-Package RxJS-All
+    Install-Package RxJS-Lite
+    Install-Package RxJS-Main
+    Install-Package RxJS-Aggregates
+    Install-Package RxJS-Async
+    Install-Package RxJS-BackPressure
+    Install-Package RxJS-Binding
+    Install-Package RxJS-Coincidence
+    Install-Package RxJS-Experimental
+    Install-Package RxJS-JoinPatterns
+    Install-Package RxJS-Testing
+    Install-Package RxJS-Time
+
+### In a Browser:
+
+```html
+<!-- Just the core RxJS -->
+<script src="rx.js"></script>
+
+<!-- Or all of RxJS minus testing -->
+<script src="rx.all.js"></script>
+
+<!-- Or keeping it lite -->
+<script src="rx.lite.js"></script>
+```
+
+### Along with a number of our extras for RxJS:
+
+```html
+<script src="rx.aggregates.js"></script>
+<script src="rx.async.js"></script>
+<script src="rx.backpressure.js"></script>
+<script src="rx.binding.js"></script>
+<script src="rx.coincidencejs"></script>
+<script src="rx.experimental.js"></script>
+<script src="rx.joinpatterns.js"></script>
+<script src="rx.time.js"></script>
+<script src="rx.virtualtime.js"></script>
+<script src="rx.testing.js"></script>
+```
+
+### Using RxJS with an AMD loader such as Require.js
+
+```js
+require({
+  'paths': {
+    'rx': 'path/to/rx-lite.js'
+  }
+},
+['rx'], function(Rx) {
+  var obs = Rx.Observable.of(42);
+  obs.forEach(function (x) { console.log(x); });
+});
+```
+

+In addition, we have support for [common Node.js functions](https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/nodejs/nodejs.md) such as binding to callbacks and the `EventEmitter` class.
+
+## Compatibility ##
+
+RxJS has been thoroughly tested against all major browsers and supports IE6+, Chrome 4+, FireFox 1+, and Node.js v0.4+.
+
+## Contributing ##
+
+There are lots of ways to contribute to the project, and we appreciate our [contributors](https://github.com/Reactive-Extensions/RxJS/wiki/Contributors).  If you wish to contribute, check out our [style guide]((https://github.com/Reactive-Extensions/RxJS/tree/master/doc/contributing)).
+
+You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
+
+[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+```
+> require('./')('one two three -- four five --six'.split(' '), { '--': true })
+{ _: [ 'one', 'two', 'three' ],
+  '--': [ 'four', 'five', '--six' ] }
+```
+
+Note that with `opts['--']` set, parsing for arguments still stops after the
+`--`.

+
+A robust Punycode converter that fully complies to [RFC 3492](http://tools.ietf.org/html/rfc3492) and [RFC 5891](http://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
+
+This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
+
+* [The C example code from RFC 3492](http://tools.ietf.org/html/rfc3492#appendix-C)
+* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
+* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
+* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
+* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
+
+This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc).
+
+## Installation
+
+Via [npm](http://npmjs.org/) (only required for Node.js releases older than v0.6.2):
+
+```bash
+npm install punycode
+```
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install punycode
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install bestiejs/punycode.js
+```
+
+In a browser:
+
+```html
+<script src="punycode.js"></script>
+```
+
+In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
+
+```js
+var punycode = require('punycode');
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('punycode.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'punycode': 'path/to/punycode'
+    }
+  },
+  ['punycode'],
+  function(punycode) {
+    console.log(punycode);
+  }
+);
+```
+
+## API
+
+### `punycode.decode(string)`
+
+Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
+
+```js
+// decode domain name parts
+punycode.decode('maana-pta'); // 'mañana'
+punycode.decode('--dqo34k'); // '☃-⌘'
+```
+
+### `punycode.encode(string)`
+
+Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
+
+```js
+// encode domain name parts
+punycode.encode('mañana'); // 'maana-pta'
+punycode.encode('☃-⌘'); // '--dqo34k'
+```
+
+### `punycode.toUnicode(input)`
+
+Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
+
+```js
+// decode domain names
+punycode.toUnicode('xn--maana-pta.com');
+// → 'mañana.com'
+punycode.toUnicode('xn----dqo34k.com');
+// → '☃-⌘.com'
+
+// decode email addresses
+punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
+// → 'джумла@джpумлатест.bрфa'
+```
+
+### `punycode.toASCII(input)`
+
+Converts a Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that's already in ASCII.
+
+```js
+// encode domain names
+punycode.toASCII('mañana.com');
+// → 'xn--maana-pta.com'
+punycode.toASCII('☃-⌘.com');
+// → 'xn----dqo34k.com'
+
+// encode email addresses
+punycode.toASCII('джумла@джpумлатест.bрфa');
+// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
+```
+
+### `punycode.ucs2`
+
+#### `punycode.ucs2.decode(string)`
+
+Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
+
+```js
+punycode.ucs2.decode('abc');
+// → [0x61, 0x62, 0x63]
+// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
+punycode.ucs2.decode('\uD834\uDF06');
+// → [0x1D306]
+```
+
+#### `punycode.ucs2.encode(codePoints)`
+
+Creates a string based on an array of numeric code point values.
+
+```js
+punycode.ucs2.encode([0x61, 0x62, 0x63]);
+// → 'abc'
+punycode.ucs2.encode([0x1D306]);
+// → '\uD834\uDF06'
+```
+
+### `punycode.version`
+
+A string representing the current Punycode.js version number.
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
+
+To generate the code coverage report, use `grunt cover`.
+
+Feel free to fork if you see possible improvements!

(So you can show `****` instead of the\n  password, for example.)\n\n* `prompt` If you are using a replacement char, and also using a\n  prompt with a readline stream (as for a `Password: *****` input),\n  then specify what the prompt is so that backspace will work\n  properly.  Otherwise, pressing backspace will overwrite the prompt\n  with the replacement character, which is weird.\n\n## ms.mute()\n\nSet `muted` to `true`.  Turns `.write()` into a no-op.\n\n## ms.unmute()\n\nSet `muted` to `false`\n\n## ms.isTTY\n\nTrue if the pipe destination is a TTY, or if the incoming pipe source is\na TTY.\n\n## Other stream methods...\n\nThe other standard readable and writable stream methods are all\navailable.  The MuteStream object acts as a facade to its pipe source\nand destination.\n",

If not supplied, the input is mandatory\n    'default': null,\n    // Automatically trim the input\n    'trim': true,\n    // A validator or an array of validators.\n    'validator': null,\n    // Automatically retry if a validator fails\n    'retry': true,\n    // Do not print what the user types\n    'silent': false,\n    // Input and output streams to read and write to\n    'input': process.stdin,\n    'output': process.stdout\n}\n```\n\nThe validators have two purposes:\n```js\nfunction (value) {\n    // Validation example, throwing an error when invalid\n    if (value.length !== 2) {\n        throw new Error('Length must be 2');\n    }\n\n    // Parse the value, modifying it\n    return value.replace('aa', 'bb');\n}\n```\n\nExample usages\n\nAsk for a name:\n```js\npromptly.prompt('Name: ', function (err, value) {\n    // err is always null in this case, because no validators are set\n    console.log(value);\n});\n```\n\nAsk for a name with a constraint (non-empty value and length > 2):\n\n```js\nvar validator = function (value) {\n    if (value.length < 2) {\n        throw new Error('Min length of 2');\n    }\n\n    return value;\n};\n\npromptly.prompt('Name: ', { validator: validator }, function (err, value) {\n    // Since retry is true by default, err is always null\n    // because promptly will be prompting for a name until it validates\n    // Between each prompt, the error message from the validator will be printed\n    console.log('Name is:', value);\n});\n```\n\nSame as above but do not retry automatically:\n\n```js\nvar validator = function (value) {\n    if (value.length < 2) {\n        throw new Error('Min length of 2');\n    }\n\n    return value;\n};\n\npromptly.prompt('Name: ', { validator: validator, retry: false }, function (err, value) {\n    if (err) {\n        console.error('Invalid name:', e.message);\n        // Manually call retry\n        // The passed error has a retry method to easily prompt again.\n        return err.retry();\n    }\n\n    console.log('Name is:', value);\n});\n```\n\n### .confirm(message, opts, fn)\n\nAsk the user to confirm something.   \nCalls `fn` with `error` and `value` (true or false).\n\nTruthy values are: `y`, `yes` and `1`.   \nFalsy values are `n`, `no`, and `0`.   \nComparison is made in a case insensitive way.\n\nExample usage:\n\n```js\npromptly.confirm('Are you sure? ', function (err, value) {\n    console.log('Answer:', value);\n});\n```\n\n\n### .choose(message, choices, opts, fn)\n\nAsk the user to choose between multiple `choices` (array of choices).   \nCalls `fn` with `error` and `value`.\n\nExample usage:\n\n```js\npromptly.choose('Do you want an apple or an orange? ', ['apple', 'orange'], function (err, value) {\n    console.log('Answer:', value);\n});\n```\n\n\n### .password(message, opts, fn)\n\nPrompts for a password, printing the `message` and waiting for the input.   \nWhen available, calls `fn` with `error` and `value`.\n\nThe available options are the same, except that `trim` and `silent` default to `false` and `default` is an empty string (to allow empty passwords).\n\nExample usage:\n\n```js\npromptly.password('Type a password: ', function (err, value) {\n    console.log('Password is:', value);\n});\n```\n\n\n## License\n\nReleased under the [MIT License](http://www.opensource.org/licenses/mit-license.php).\n",

+# bl *(BufferList)*
+
+**A Node.js Buffer list collector, reader and streamer thingy.**
+
+[![NPM](https://nodei.co/npm/bl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/bl/)
+[![NPM](https://nodei.co/npm-dl/bl.png?months=6&height=3)](https://nodei.co/npm/bl/)
+
+**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
+
+The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
+
+```js
+const BufferList = require('bl')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append('hi')                     // bl will also accept & convert Strings
+bl.append(new Buffer('j'))
+bl.append(new Buffer([ 0x3, 0x4 ]))
+
+console.log(bl.length) // 12
+
+console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
+console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
+console.log(bl.slice(3, 6).toString('ascii'))  // 'def'
+console.log(bl.slice(3, 8).toString('ascii'))  // 'defgh'
+console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
+
+// or just use toString!
+console.log(bl.toString())               // 'abcdefghij\u0003\u0004'
+console.log(bl.toString('ascii', 3, 8))  // 'defgh'
+console.log(bl.toString('ascii', 5, 10)) // 'fghij'
+
+// other standard Buffer readables
+console.log(bl.readUInt16BE(10)) // 0x0304
+console.log(bl.readUInt16LE(10)) // 0x0403
+```
+
+Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
+
+```js
+const bl = require('bl')
+    , fs = require('fs')
+
+fs.createReadStream('README.md')
+  .pipe(bl(function (err, data) { // note 'new' isn't strictly required
+    // `data` is a complete Buffer object containing the full data
+    console.log(data.toString())
+  }))
+```
+
+Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
+
+Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
+```js
+const hyperquest = require('hyperquest')
+    , bl         = require('bl')
+    , url        = 'https://raw.github.com/rvagg/bl/master/README.md'
+
+hyperquest(url).pipe(bl(function (err, data) {
+  console.log(data.toString())
+}))
+```
+
+Or, use it as a readable stream to recompose a list of Buffers to an output source:
+
+```js
+const BufferList = require('bl')
+    , fs         = require('fs')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append(new Buffer('hi'))
+bl.append(new Buffer('j'))
+
+bl.pipe(fs.createWriteStream('gibberish.txt'))
+```

+--------------------------------------------------------
+<a name="ctor"></a>
+### new BufferList([ callback | buffer | buffer array ])
+The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
+
+Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
+
+`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
+
+```js
+var bl = require('bl')
+var myinstance = bl()
+
+// equivilant to:
+
+var BufferList = require('bl')
+var myinstance = new BufferList()
+```
+
+--------------------------------------------------------
+<a name="length"></a>
+### bl.length
+Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
+
+--------------------------------------------------------
+<a name="append"></a>
+### bl.append(buffer)
+`append(buffer)` adds an additional buffer or BufferList to the internal list.
+
+--------------------------------------------------------
+<a name="get"></a>
+### bl.get(index)
+`get()` will return the byte at the specified index.
+
+--------------------------------------------------------
+<a name="slice"></a>
+### bl.slice([ start, [ end ] ])
+`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
+
+If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
+
+--------------------------------------------------------
+<a name="copy"></a>
+### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
+`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
+
+--------------------------------------------------------
+<a name="duplicate"></a>
+### bl.duplicate()
+`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
+
+```js
+var bl = new BufferList()
+
+bl.append('hello')
+bl.append(' world')
+bl.append('\n')
+
+bl.duplicate().pipe(process.stdout, { end: false })
+
+console.log(bl.toString())
+```
+
+--------------------------------------------------------
+<a name="consume"></a>
+### bl.consume(bytes)
+`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
+
+--------------------------------------------------------
+<a name="toString"></a>
+### bl.toString([encoding, [ start, [ end ]]])
+`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
+
+--------------------------------------------------------
+<a name="readXX"></a>
+### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
+
+All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
+
+See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
+
+--------------------------------------------------------
+<a name="streams"></a>
+### Streams
+**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance.

+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+# node-http-signature
+
+node-http-signature is a node.js library that has client and server components
+for Joyent's [HTTP Signature Scheme](http_signing.md).
+
+## Usage
+
+Note the example below signs a request with the same key/cert used to start an
+HTTP server. This is almost certainly not what you actually want, but is just
+used to illustrate the API calls; you will need to provide your own key
+management in addition to this library.
+
+### Client
+
+```js
+var fs = require('fs');
+var https = require('https');
+var httpSignature = require('http-signature');
+
+var key = fs.readFileSync('./key.pem', 'ascii');
+
+var options = {
+  host: 'localhost',
+  port: 8443,
+  path: '/',
+  method: 'GET',
+  headers: {}
+};
+
+// Adds a 'Date' header in, signs it, and adds the
+// 'Authorization' header in.
+var req = https.request(options, function(res) {
+  console.log(res.statusCode);
+});
+
+
+httpSignature.sign(req, {
+  key: key,
+  keyId: './cert.pem'
+});
+
+req.end();
+```
+
+### Server
+
+```js
+var fs = require('fs');
+var https = require('https');
+var httpSignature = require('http-signature');
+
+var options = {
+  key: fs.readFileSync('./key.pem'),
+  cert: fs.readFileSync('./cert.pem')
+};
+
+https.createServer(options, function (req, res) {
+  var rc = 200;
+  var parsed = httpSignature.parseRequest(req);
+  var pub = fs.readFileSync(parsed.keyId, 'ascii');
+  if (!httpSignature.verifySignature(parsed, pub))
+    rc = 401;
+
+  res.writeHead(rc);
+  res.end();
+}).listen(8443);
+```
+
+## Installation
+
+    npm install http-signature
+
+## License
+
+MIT.
+
+## Bugs
+
+See <https://github.com/joyent/node-http-signature/issues>.

+# Abstract
+
+This document describes a way to add origin authentication, message integrity,
+and replay resistance to HTTP REST requests.  It is intended to be used over
+the HTTPS protocol.
+
+# Copyright Notice
+
+Copyright (c) 2011 Joyent, Inc. and the persons identified as document authors.

+
+# Introduction
+
+This protocol is intended to provide a standard way for clients to sign HTTP
+requests.  RFC2617 (HTTP Authentication) defines Basic and Digest authentication
+mechanisms, and RFC5246 (TLS 1.2) defines client-auth, both of which are widely
+employed on the Internet today.  However, it is common place that the burdens of
+PKI prevent web service operators from deploying that methodology, and so many
+fall back to Basic authentication, which has poor security characteristics.
+
+Additionally, OAuth provides a fully-specified alternative for authorization
+of web service requests, but is not (always) ideal for machine to machine
+communication, as the key acquisition steps (generally) imply a fixed
+infrastructure that may not make sense to a service provider (e.g., symmetric
+keys).
+
+Several web service providers have invented their own schemes for signing
+HTTP requests, but to date, none have been placed in the public domain as a
+standard.  This document serves that purpose.  There are no techniques in this
+proposal that are novel beyond previous art, however, this aims to be a simple
+mechanism for signing these requests.
+
+# Signature Authentication Scheme
+
+The "signature" authentication scheme is based on the model that the client must
+authenticate itself with a digital signature produced by either a private
+asymmetric key (e.g., RSA) or a shared symmetric key (e.g., HMAC).  The scheme
+is parameterized enough such that it is not bound to any particular key type or
+signing algorithm.  However, it does explicitly assume that clients can send an
+HTTP `Date` header.
+
+## Authorization Header
+
+The client is expected to send an Authorization header (as defined in RFC 2617)
+with the following parameterization:
+
+    credentials := "Signature" params
+    params := 1#(keyId | algorithm | [headers] | [ext] | signature)
+    digitalSignature := plain-string
+
+    keyId := "keyId" "=" <"> plain-string <">
+    algorithm := "algorithm" "=" <"> plain-string <">
+    headers := "headers" "=" <"> 1#headers-value <">
+    ext := "ext" "=" <"> plain-string <">
+    signature := "signature" "=" <"> plain-string <">
+
+    headers-value := plain-string
+    plain-string   = 1*( %x20-21 / %x23-5B / %x5D-7E )
+
+### Signature Parameters
+
+#### keyId
+
+REQUIRED.  The `keyId` field is an opaque string that the server can use to look
+up the component they need to validate the signature.  It could be an SSH key
+fingerprint, an LDAP DN, etc.  Management of keys and assignment of `keyId` is
+out of scope for this document.
+
+#### algorithm
+
+REQUIRED. The `algorithm` parameter is used if the client and server agree on a
+non-standard digital signature algorithm.  The full list of supported signature
+mechanisms is listed below.
+
+#### headers
+
+OPTIONAL.  The `headers` parameter is used to specify the list of HTTP headers
+used to sign the request.  If specified, it should be a quoted list of HTTP
+header names, separated by a single space character.  By default, only one
+HTTP header is signed, which is the `Date` header.  Note that the list MUST be
+specified in the order the values are concatenated together during signing. To
+include the HTTP request line in the signature calculation, use the special
+`request-line` value.  While this is overloading the definition of `headers` in
+HTTP linguism, the request-line is defined in RFC 2616, and as the outlier from
+headers in useful signature calculation, it is deemed simpler to simply use
+`request-line` than to add a separate parameter for it.
+
+#### extensions
+
+OPTIONAL.  The `extensions` parameter is used to include additional information
+which is covered by the request.  The content and format of the string is out of
+scope for this document, and expected to be specified by implementors.
+
+#### signature
+
+REQUIRED.  The `signature` parameter is a `Base64` encoded digital signature
+generated by the client. The client uses the `algorithm` and `headers` request
+parameters to form a canonicalized `signing string`.  This `signing string` is
+then signed with the key associated with `keyId` and the algorithm
+corresponding to `algorithm`.  The `signature` parameter is then set to the
+`Base64` encoding of the signature.
+
+### Signing String Composition
+
+In order to generate the string that is signed with a key, the client MUST take
+the values of each HTTP header specified by `headers` in the order they appear.
+
+1. If the header name is not `request-line` then append the lowercased header
+   name followed with an ASCII colon `:` and an ASCII space ` `.
+2. If the header name is `request-line` then append the HTTP request line,
+   otherwise append the header value.
+3. If value is not the last value then append an ASCII newline `\n`. The string
+   MUST NOT include a trailing ASCII newline.
+
+# Example Requests
+
+All requests refer to the following request (body omitted):
+
+    POST /foo HTTP/1.1
+    Host: example.org
+    Date: Tue, 07 Jun 2011 20:51:35 GMT
+    Content-Type: application/json
+    Content-MD5: h0auK8hnYJKmHTLhKtMTkQ==
+    Content-Length: 123
+
+The "rsa-key-1" keyId refers to a private key known to the client and a public
+key known to the server. The "hmac-key-1" keyId refers to key known to the
+client and server.
+
+## Default parameterization
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",signature="Base64(RSA-SHA256(signing string))"
+
+The client would compose the signing string as:
+
+    date: Tue, 07 Jun 2011 20:51:35 GMT
+
+## Header List
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",headers="request-line date content-type content-md5",signature="Base64(RSA-SHA256(signing string))"
+
+The client would compose the signing string as (`+ "\n"` inserted for
+readability):
+
+    POST /foo HTTP/1.1 + "\n"
+    date: Tue, 07 Jun 2011 20:51:35 GMT + "\n"
+    content-type: application/json + "\n"
+    content-md5: h0auK8hnYJKmHTLhKtMTkQ==
+
+## Algorithm
+
+The authorization header and signature would be generated as:
+
+    Authorization: Signature keyId="hmac-key-1",algorithm="hmac-sha1",signature="Base64(HMAC-SHA1(signing string))"
+
+The client would compose the signing string as:
+
+    date: Tue, 07 Jun 2011 20:51:35 GMT
+
+# Signing Algorithms
+
+Currently supported algorithm names are:
+
+* rsa-sha1
+* rsa-sha256
+* rsa-sha512
+* dsa-sha1
+* hmac-sha1
+* hmac-sha256
+* hmac-sha512
+
+# Security Considerations
+
+## Default Parameters
+
+Note the default parameterization of the `Signature` scheme is only safe if all
+requests are carried over a secure transport (i.e., TLS).  Sending the default
+scheme over a non-secure transport will leave the request vulnerable to
+spoofing, tampering, replay/repudiation, and integrity violations (if using the
+STRIDE threat-modeling methodology).
+
+## Insecure Transports
+
+If sending the request over plain HTTP, service providers SHOULD require clients
+to sign ALL HTTP headers, and the `request-line`.  Additionally, service
+providers SHOULD require `Content-MD5` calculations to be performed to ensure
+against any tampering from clients.
+
+## Nonces
+
+Nonces are out of scope for this document simply because many service providers
+fail to implement them correctly, or do not adopt security specifications
+because of the infrastructure complexity.  Given the `header` parameterization,
+a service provider is fully enabled to add nonce semantics into this scheme by
+using something like an `x-request-nonce` header, and ensuring it is signed
+with the `Date` header.
+
+## Clock Skew
+
+As the default scheme is to sign the `Date` header, service providers SHOULD
+protect against logged replay attacks by enforcing a clock skew.  The server
+SHOULD be synchronized with NTP, and the recommendation in this specification
+is to allow 300s of clock skew (in either direction).
+
+## Required Headers to Sign
+
+It is out of scope for this document to dictate what headers a service provider
+will want to enforce, but service providers SHOULD at minimum include the
+`Date` header.

+# node-uuid
+
+Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.
+
+Features:
+
+* Generate RFC4122 version 1 or version 4 UUIDs
+* Runs in node.js and all browsers.
+* Registered as a [ComponentJS](https://github.com/component/component) [component](https://github.com/component/component/wiki/Components) ('broofa/node-uuid').
+* Cryptographically strong random # generation on supporting platforms
+* 1.1K minified and gzip'ed  (Want something smaller?  Check this [crazy shit](https://gist.github.com/982883) out! )
+* [Annotated source code](http://broofa.github.com/node-uuid/docs/uuid.html)
+* Comes with a Command Line Interface for generating uuids on the command line
+
+## Getting Started
+
+Install it in your browser:
+
+```html
+<script src="uuid.js"></script>
+```
+
+Or in node.js:
+
+```
+npm install node-uuid
+```
+
+```javascript
+var uuid = require('node-uuid');
+```
+
+Then create some ids ...
+
+```javascript
+// Generate a v1 (time-based) id
+uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+
+// Generate a v4 (random) id
+uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'
+```
+
+## API
+
+### uuid.v1([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v1 (timestamp-based) UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID.  See note 1.
+  * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence.  Default: An internally maintained clockseq is used.
+  * `msecs` - (Number | Date) Time in milliseconds since unix Epoch.  Default: The current time is used.
+  * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Notes:
+
+1. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v1({
+  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
+  clockseq: 0x1234,
+  msecs: new Date('2011-11-01').getTime(),
+  nsecs: 5678
+});   // -> "710b962e-041c-11e1-9234-0123456789ab"
+```
+
+Example: In-place generation of two binary IDs
+
+```javascript
+// Generate two ids in an array
+var arr = new Array(32); // -> []
+uuid.v1(null, arr, 0);   // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15]
+uuid.v1(null, arr, 16);  // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15 02 a3 1c b0 14 32 11 e1 85 58 0b 48 8e 4f c1 15]
+
+// Optionally use uuid.unparse() to get stringify the ids
+uuid.unparse(buffer);    // -> '02a2ce90-1432-11e1-8558-0b488e4fc115'
+uuid.unparse(buffer, 16) // -> '02a31cb0-1432-11e1-8558-0b488e4fc115'
+```
+
+### uuid.v4([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v4 UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values
+  * `rng` - (Function) Random # generator to use.  Set to one of the built-in generators - `uuid.mathRNG` (all platforms), `uuid.nodeRNG` (node.js only), `uuid.whatwgRNG` (WebKit only) - or a custom function that returns an array[16] of byte values.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v4({
+  random: [
+    0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,
+    0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36
+  ]
+});
+// -> "109156be-c4fb-41ea-b1b4-efe1671c5836"
+```
+
+Example: Generate two IDs in a single buffer
+
+```javascript
+var buffer = new Array(32); // (or 'new Buffer' in node.js)
+uuid.v4(null, buffer, 0);
+uuid.v4(null, buffer, 16);
+```
+
+### uuid.parse(id[, buffer[, offset]])
+### uuid.unparse(buffer[, offset])
+
+Parse and unparse UUIDs
+
+  * `id` - (String) UUID(-like) string
+  * `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written. Default: A new Array or Buffer is used
+  * `offset` - (Number) Starting index in `buffer` at which to begin writing. Default: 0
+
+Example parsing and unparsing a UUID string
+
+```javascript
+var bytes = uuid.parse('797ff043-11eb-11e1-80d6-510998755d10'); // -> <Buffer 79 7f f0 43 11 eb 11 e1 80 d6 51 09 98 75 5d 10>
+var string = uuid.unparse(bytes); // -> '797ff043-11eb-11e1-80d6-510998755d10'
+```
+
+### uuid.noConflict()
+
+(Browsers only) Set `uuid` property back to it's previous value.
+
+Returns the node-uuid object.
+
+Example:
+
+```javascript
+var myUuid = uuid.noConflict();
+myUuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+```
+
+## Deprecated APIs
+
+Support for the following v1.2 APIs is available in v1.3, but is deprecated and will be removed in the next major version.
+
+### uuid([format [, buffer [, offset]]])
+
+uuid() has become uuid.v4(), and the `format` argument is now implicit in the `buffer` argument. (i.e. if you specify a buffer, the format is assumed to be binary).
+
+### uuid.BufferClass
+
+The class of container created when generating binary uuid data if no buffer argument is specified.  This is expected to go away, with no replacement API.
+
+## Command Line Interface
+
+To use the executable, it's probably best to install this library globally.
+
+`npm install -g node-uuid`
+
+Usage:
+
+```
+USAGE: uuid [version] [options]
+
+
+options:
+
+--help                     Display this message and exit
+```
+
+`version` must be an RFC4122 version that is supported by this library, which is currently version 1 and version 4 (denoted by "v1" and "v4", respectively). `version` defaults to version 4 when not supplied.
+
+### Examples
+
+```
+> uuid
+3a91f950-dec8-4688-ba14-5b7bbfc7a563
+```
+
+```
+> uuid v1
+9d0b43e0-7696-11e3-964b-250efa37a98e
+```
+
+```
+> uuid v4
+6790ac7c-24ac-4f98-8464-42f6d98a53ae
+```
+
+## Testing
+
+In node.js
+
+```
+npm test
+```
+
+In Browser
+
+```
+open test/test.html
+```
+
+### Benchmarking
+
+Requires node.js
+
+```
+npm install uuid uuid-js
+node benchmark/benchmark.js
+```
+
+For a more complete discussion of node-uuid performance, please see the `benchmark/README.md` file, and the [benchmark wiki](https://github.com/broofa/node-uuid/wiki/Benchmark)
+
+For browser performance [checkout the JSPerf tests](http://jsperf.com/node-uuid-performance).
+

+
+A robust Punycode converter that fully complies to [RFC 3492](http://tools.ietf.org/html/rfc3492) and [RFC 5891](http://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
+
+This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
+
+* [The C example code from RFC 3492](http://tools.ietf.org/html/rfc3492#appendix-C)
+* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
+* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
+* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
+* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
+
+This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc).
+
+## Installation
+
+Via [npm](http://npmjs.org/) (only required for Node.js releases older than v0.6.2):
+
+```bash
+npm install punycode
+```
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install punycode
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install bestiejs/punycode.js
+```
+
+In a browser:
+
+```html
+<script src="punycode.js"></script>
+```
+
+In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
+
+```js
+var punycode = require('punycode');
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('punycode.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'punycode': 'path/to/punycode'
+    }
+  },
+  ['punycode'],
+  function(punycode) {
+    console.log(punycode);
+  }
+);
+```
+
+## API
+
+### `punycode.decode(string)`
+
+Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
+
+```js
+// decode domain name parts
+punycode.decode('maana-pta'); // 'mañana'
+punycode.decode('--dqo34k'); // '☃-⌘'
+```
+
+### `punycode.encode(string)`
+
+Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
+
+```js
+// encode domain name parts
+punycode.encode('mañana'); // 'maana-pta'
+punycode.encode('☃-⌘'); // '--dqo34k'
+```
+
+### `punycode.toUnicode(input)`
+
+Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
+
+```js
+// decode domain names
+punycode.toUnicode('xn--maana-pta.com');
+// → 'mañana.com'
+punycode.toUnicode('xn----dqo34k.com');
+// → '☃-⌘.com'
+
+// decode email addresses
+punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
+// → 'джумла@джpумлатест.bрфa'
+```
+
+### `punycode.toASCII(input)`
+
+Converts a Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that's already in ASCII.
+
+```js
+// encode domain names
+punycode.toASCII('mañana.com');
+// → 'xn--maana-pta.com'
+punycode.toASCII('☃-⌘.com');
+// → 'xn----dqo34k.com'
+
+// encode email addresses
+punycode.toASCII('джумла@джpумлатест.bрфa');
+// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
+```
+
+### `punycode.ucs2`
+
+#### `punycode.ucs2.decode(string)`
+
+Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
+
+```js
+punycode.ucs2.decode('abc');
+// → [0x61, 0x62, 0x63]
+// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
+punycode.ucs2.decode('\uD834\uDF06');
+// → [0x1D306]
+```
+
+#### `punycode.ucs2.encode(codePoints)`
+
+Creates a string based on an array of numeric code point values.
+
+```js
+punycode.ucs2.encode([0x61, 0x62, 0x63]);
+// → 'abc'
+punycode.ucs2.encode([0x1D306]);
+// → '\uD834\uDF06'
+```
+
+### `punycode.version`
+
+A string representing the current Punycode.js version number.
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
+
+To generate the code coverage report, use `grunt cover`.
+
+Feel free to fork if you see possible improvements!

+# stringify-object [![Build Status](https://secure.travis-ci.org/yeoman/stringify-object.svg?branch=master)](http://travis-ci.org/yeoman/stringify-object)
+
+> Stringify an object/array like JSON.stringify just without all the double-quotes.
+
+Useful for when you want to get the string representation of an object in a formatted way.
+
+It also handles circular references and lets you specify quote type.
+
+
+## Install
+
+```sh
+$ npm install --save stringify-object
+```
+
+
+## Usage
+
+```js
+var obj = {
+    foo: 'bar',
+    'arr': [1, 2, 3],
+    nested: { hello: "world" }
+};
+
+var pretty = stringifyObject(obj, {
+    indent: '  ',
+    singleQuotes: false
+});
+
+console.log(pretty);
+/*
+{
+  foo: "bar",
+  arr: [
+    1,
+    2,
+    3
+  ],
+  nested: {
+    hello: "world"
+  }
+}
+*/
+```
+
+
+## API
+
+### stringifyObject(object, [options])
+
+Accepts an object to stringify and optionally an option object. Circular references will be replaced with `null`.
+
+#### options
+
+##### indent
+
+Type: `string`  
+Default: `'\t'`
+
+Choose the indentation you prefer.
+
+##### singleQuotes
+
+Type: `boolean`  
+Default: `true`
+
+Set to false to get double-quoted strings.

+# bl *(BufferList)*
+
+**A Node.js Buffer list collector, reader and streamer thingy.**
+
+[![NPM](https://nodei.co/npm/bl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/bl/)
+[![NPM](https://nodei.co/npm-dl/bl.png?months=6&height=3)](https://nodei.co/npm/bl/)
+
+**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
+
+The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
+
+```js
+const BufferList = require('bl')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append('hi')                     // bl will also accept & convert Strings
+bl.append(new Buffer('j'))
+bl.append(new Buffer([ 0x3, 0x4 ]))
+
+console.log(bl.length) // 12
+
+console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
+console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
+console.log(bl.slice(3, 6).toString('ascii'))  // 'def'
+console.log(bl.slice(3, 8).toString('ascii'))  // 'defgh'
+console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
+
+// or just use toString!
+console.log(bl.toString())               // 'abcdefghij\u0003\u0004'
+console.log(bl.toString('ascii', 3, 8))  // 'defgh'
+console.log(bl.toString('ascii', 5, 10)) // 'fghij'
+
+// other standard Buffer readables
+console.log(bl.readUInt16BE(10)) // 0x0304
+console.log(bl.readUInt16LE(10)) // 0x0403
+```
+
+Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
+
+```js
+const bl = require('bl')
+    , fs = require('fs')
+
+fs.createReadStream('README.md')
+  .pipe(bl(function (err, data) { // note 'new' isn't strictly required
+    // `data` is a complete Buffer object containing the full data
+    console.log(data.toString())
+  }))
+```
+
+Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
+
+Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
+```js
+const hyperquest = require('hyperquest')
+    , bl         = require('bl')
+    , url        = 'https://raw.github.com/rvagg/bl/master/README.md'
+
+hyperquest(url).pipe(bl(function (err, data) {
+  console.log(data.toString())
+}))
+```
+
+Or, use it as a readable stream to recompose a list of Buffers to an output source:
+
+```js
+const BufferList = require('bl')
+    , fs         = require('fs')
+
+var bl = new BufferList()
+bl.append(new Buffer('abcd'))
+bl.append(new Buffer('efg'))
+bl.append(new Buffer('hi'))
+bl.append(new Buffer('j'))
+
+bl.pipe(fs.createWriteStream('gibberish.txt'))
+```

+--------------------------------------------------------
+<a name="ctor"></a>
+### new BufferList([ callback | buffer | buffer array ])
+The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
+
+Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
+
+`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
+
+```js
+var bl = require('bl')
+var myinstance = bl()
+
+// equivilant to:
+
+var BufferList = require('bl')
+var myinstance = new BufferList()
+```
+
+--------------------------------------------------------
+<a name="length"></a>
+### bl.length
+Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
+
+--------------------------------------------------------
+<a name="append"></a>
+### bl.append(buffer)
+`append(buffer)` adds an additional buffer or BufferList to the internal list.
+
+--------------------------------------------------------
+<a name="get"></a>
+### bl.get(index)
+`get()` will return the byte at the specified index.
+
+--------------------------------------------------------
+<a name="slice"></a>
+### bl.slice([ start, [ end ] ])
+`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
+
+If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
+
+--------------------------------------------------------
+<a name="copy"></a>
+### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
+`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
+
+--------------------------------------------------------
+<a name="duplicate"></a>
+### bl.duplicate()
+`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
+
+```js
+var bl = new BufferList()
+
+bl.append('hello')
+bl.append(' world')
+bl.append('\n')
+
+bl.duplicate().pipe(process.stdout, { end: false })
+
+console.log(bl.toString())
+```
+
+--------------------------------------------------------
+<a name="consume"></a>
+### bl.consume(bytes)
+`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
+
+--------------------------------------------------------
+<a name="toString"></a>
+### bl.toString([encoding, [ start, [ end ]]])
+`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
+
+--------------------------------------------------------
+<a name="readXX"></a>
+### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
+
+All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
+
+See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
+
+--------------------------------------------------------
+<a name="streams"></a>
+### Streams
+**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance.

+# readable-stream
+
+***Node-core streams for userland***
+
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+JS-YAML - YAML 1.2 parser and serializer for JavaScript
+=======================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+[Online Demo](http://nodeca.github.com/js-yaml/)
+
+
+This is an implementation of [YAML](http://yaml.org/), a human friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resourses to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+yaml = require('js-yaml');
+fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  var doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns a JavaScript
+object or throws `YAMLException` on error. By default, does not support regexps,
+functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will throw on warnings if this function is not provided.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, JSON schema is not as strict as defined in the YAML specification.
+It allows numbers in any notaion, use `Null` and `NULL` as `null`, etc.
+Core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources you
+must additionally validate object structure, to avoid injections:
+
+``` javascript
+var untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string, iterator [ , options ])
+
+Same as `safeLoad()`, but understands multi-document sources and apply
+`iterator` to each document.
+
+``` javascript
+var yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string, iterator [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw exception if you try to dump regexps or functions. However, you can
+disable exceptions by `skipInvalid` option.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+
+styles:
+
+``` none
+!!null
+  "canonical"   => "~"
+
+!!int
+  "binary"      => "0b1", "0b101010", "0b1110001111010"
+  "octal"       => "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" => "0x1", "0x2A", "0x1C7A"
+
+!!null, !!bool, !!float
+  "lowercase"   => "null", "true", "false", ".nan", '.inf'
+  "uppercase"   => "NULL", "TRUE", "FALSE", ".NAN", '.INF'
+  "camelcase"   => "Null", "True", "False", ".NaN", '.Inf'
+```
+
+By default, !!int uses `decimal`, and !!null, !!bool, !!float use `lowercase`.
+
+
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).

+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS do not allows objects
+or array as keys, and stringifies (by calling .toString method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
+
+
+Breaking changes in 2.x.x -> 3.x.x
+----------------------------------
+
+If your have not used __custom__ tags or loader classes and not loaded yaml
+files via `require()` - no changes needed. Just upgrade library.
+
+In other case, you should:
+
+1. Replace all occurences of `require('xxxx.yml')` by `fs.readFileSync()` +
+  `yaml.safeLoad()`.
+2. rewrite your custom tags constructors and custom loader
+  classes, to conform new API. See
+  [examples](https://github.com/nodeca/js-yaml/tree/master/examples) and
+  [wiki](https://github.com/nodeca/js-yaml/wiki) for details.

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.png?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4
+{ foo: '3', bar: '4' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({paramters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supportied yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument([names or flags], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flags``` - Either a name or a list of option strings, e.g. foo or -f, --foo.
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+ * - `description`  A description of what the program does
+ * - `epilog`  Text following the argument descriptions
+ * - `parents`  Parsers whose arguments should be copied into this one
+ * - `formatterClass`  HelpFormatter class for printing help messages
+ * - `prefixChars`  Characters that prefix optional arguments
+ * - `fromfilePrefixChars` Characters that prefix files containing additional arguments
+ * - `argumentDefault`  The default value for all arguments
+ * - `addHelp`  Add a -h/-help option
+ * - `conflictHandler`  Specifies how to handle conflicting argument names
+ * - `debug`  Enable debug mode. Argument errors throw exception in

+# lodash v3.2.0
+
+The [modern build](https://github.com/lodash/lodash/wiki/Build-Differences) of [lodash](https://lodash.com/) exported as [Node.js](http://nodejs.org/)/[io.js](https://iojs.org/) modules.
+
+Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
+```bash
+$ lodash modularize modern exports=node -o ./
+$ lodash modern -d -o ./index.js
+```
+
+## Installation
+
+Using npm:
+
+```bash
+$ {sudo -H} npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js/io.js:
+
+```js
+// load the modern build
+var _ = require('lodash');
+// or a method category
+var array = require('lodash/array');
+// or a method
+var chunk = require('lodash/array/chunk');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/3.2.0-npm) for more details.
+
+**Note:**<br>
+Don’t assign values to the [special variable](http://nodejs.org/api/repl.html#repl_repl_features) `_` when in the REPL.<br>
+Install [n_](https://www.npmjs.com/package/n_) for a REPL that includes lodash by default.
+
+## Module formats

+ * Creates a `lodash` object which wraps `value` to enable implicit chaining.
+ * Methods that operate on and return arrays, collections, and functions can
+ * be chained together. Methods that return a boolean or single value will
+ * automatically end the chain returning the unwrapped value. Explicit chaining
+ * may be enabled using `_.chain`. The execution of chained methods is lazy,
+ * that is, execution is deferred until `_#value` is implicitly or explicitly
+ * called.
+ *
+ * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
+ * fusion is an optimization that merges iteratees to avoid creating intermediate
+ * arrays and reduce the number of iteratee executions.
+ *
+ * Chaining is supported in custom builds as long as the `_#value` method is
+ * directly or indirectly included in the build.
+ *
+ * In addition to lodash methods, wrappers also have the following `Array` methods:
+ * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
+ * and `unshift`
+ *
+ * The wrapper methods that support shortcut fusion are:
+ * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
+ * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
+ * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
+ * and `where`
+ *
+ * The chainable wrapper methods are:
+ * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
+ * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
+ * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
+ * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
+ * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
+ * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
+ * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
+ * `keysIn`, `map`, `mapValues`, `matches`, `memoize`, `merge`, `mixin`,
+ * `negate`, `noop`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
+ * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
+ * `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `reverse`,
+ * `shuffle`, `slice`, `sort`, `sortBy`, `sortByAll`, `splice`, `spread`,

+ * `unshift`, `unzip`, `values`, `valuesIn`, `where`, `without`, `wrap`, `xor`,
+ * `zip`, and `zipObject`

+# sprintf.js
+**sprintf.js** is a complete open source JavaScript sprintf implementation for the *browser* and *node.js*.
+
+Its prototype is simple:
+
+    string sprintf(string format , [mixed arg1 [, mixed arg2 [ ,...]]])
+
+The placeholders in the format string are marked by `%` and are followed by one or more of these elements, in this order:
+
+* An optional number followed by a `$` sign that selects which argument index to use for the value. If not specified, arguments will be placed in the same order as the placeholders in the input string.
+* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers.
+* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*.
+* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result.
+* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded.
+* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used on a string, it causes the result to be truncated.
+* A type specifier that can be any of:
+    * `%` — yields a literal `%` character
+    * `b` — yields an integer as a binary number
+    * `c` — yields an integer as the character with that ASCII value
+    * `d` or `i` — yields an integer as a signed decimal number
+    * `e` — yields a float using scientific notation
+    * `u` — yields an integer as an unsigned decimal number
+    * `f` — yields a float as is
+    * `o` — yields an integer as an octal number
+    * `s` — yields a string as is
+    * `x` — yields an integer as a hexadecimal number (lower-case)
+    * `X` — yields an integer as a hexadecimal number (upper-case)
+
+## JavaScript `vsprintf`
+`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments:
+
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])
+
+## Argument swapping
+You can also swap the arguments. That is, the order of the placeholders doesn't have to match the order of the arguments. You can do that by simply indicating in the format string which arguments the placeholders refer to:
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+And, of course, you can repeat the placeholders without having to increase the number of arguments.
+
+## Named arguments
+Format strings may contain replacement fields rather than positional placeholders. Instead of referring to a certain argument, you can now refer to a certain key within an object. Replacement fields are surrounded by rounded parentheses - `(` and `)` - and begin with a keyword that refers to a key:
+
+    var user = {
+        name: "Dolly"
+    }
+    sprintf("Hello %(name)s", user) // Hello Dolly
+Keywords in replacement fields can be optionally followed by any number of keywords or indexes:
+
+    var users = [
+        {name: "Dolly"},
+        {name: "Molly"},
+        {name: "Polly"}
+    ]
+    sprintf("Hello %(users[0].name)s, %(users[1].name)s and %(users[2].name)s", {users: users}) // Hello Dolly, Molly and Polly
+Note: mixing positional and named placeholders is not (yet) supported
+
+## Computed values
+You can pass in a function as a dynamic value and it will be invoked (with no arguments) in order to compute the value on-the-fly.
+
+    sprintf("Current timestamp: %d", Date.now) // Current timestamp: 1398005382890
+    sprintf("Current date and time: %s", function() { return new Date().toString() })
+
+# AngularJS
+You can now use `sprintf` and `vsprintf` (also aliased as `fmt` and `vfmt` respectively) in your AngularJS projects. See `demo/`.
+
+# Installation
+
+## Via Bower
+
+    bower install sprintf
+
+## Or as a node.js module
+
+    npm install sprintf-js
+
+### Usage
+
+    var sprintf = require("sprintf-js").sprintf,
+        vsprintf = require("sprintf-js").vsprintf
+
+    sprintf("%2$s %3$s a %1$s", "cracker", "Polly", "wants")
+    vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"])

+**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
+standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+parser written in ECMAScript (also popularly known as
+[JavaScript](http://en.wikipedia.org/wiki/JavaScript>JavaScript)).
+Esprima is created and maintained by [Ariya Hidayat](http://twitter.com/ariyahidayat),
+with the help of [many contributors](https://github.com/jquery/esprima/contributors).
+
+### Features
+
+- Full support for ECMAScript 5.1 ([ECMA-262](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
+- Sensible [syntax tree format](http://esprima.org/doc/index.html#ast) compatible with Mozilla
+[Parser AST](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
+- Optional tracking of syntax node location (index-based and line-column)
+- Heavily tested (> 700 [unit tests](http://esprima.org/test/) with [full code coverage](http://esprima.org/test/coverage.html))
+- [Partial support](http://esprima.org/doc/es6.html) for ECMAScript 6
+
+Esprima serves as a **building block** for some JavaScript
+language tools, from [code instrumentation](http://esprima.org/demo/functiontrace.html)
+to [editor autocompletion](http://esprima.org/demo/autocomplete.html).
+
+Esprima runs on many popular web browsers, as well as other ECMAScript platforms such as
+[Rhino](http://www.mozilla.org/rhino), [Nashorn](http://openjdk.java.net/projects/nashorn/), and [Node.js](https://npmjs.org/package/esprima).
+
+For more information, check the web site [esprima.org](http://esprima.org).

+# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
+
+> ES6 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) ponyfill
+
+> Ponyfill: A polyfill that doesn't overwrite the native method
+
+
+## Install
+
+```sh
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+var objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, source, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

+# xdg-basedir [![Build Status](https://travis-ci.org/sindresorhus/xdg-basedir.svg?branch=master)](https://travis-ci.org/sindresorhus/xdg-basedir)
+
+> Get [XDG Base Directory](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) paths
+
+
+## Install
+
+```sh
+$ npm install --save xdg-basedir
+```
+
+
+## Usage
+
+```js
+var xdgBasedir = require('xdg-basedir');
+
+xdgBasedir.data;
+//=> /home/sindresorhus/.local/share
+
+xdgBasedir.config;
+//=> /home/sindresorhus/.config
+
+xdgBasedir.dataDirs
+//=> ['/home/sindresorhus/.local/share', '/usr/local/share/', '/usr/share/']
+```
+
+
+## API
+
+The properties `.data`, `.config`, `.cache`, `.runtime` will return `null` in the uncommon case that both the XDG environment variable is not set and the users home directory can't be found. You need to handle this case. A common solution is to [fall back to a temp directory](https://github.com/yeoman/configstore/blob/b82690fc401318ad18dcd7d151a0003a4898a314/index.js#L15).
+
+### .data
+
+Directory for user specific data files.
+
+### .config
+
+Directory for user specific configuration files.
+
+### .cache
+
+Directory for user specific non-essential data files.
+
+### .runtime
+
+Directory for user-specific non-essential runtime files and other file objects (such as sockets, named pipes, etc).
+
+### .dataDirs
+
+Preference-ordered array of base directories to search for data files in addition to `.data`.
+
+### .configDirs
+
+Preference-ordered array of base directories to search for configuration files in addition to `.config`.

+# configstore [![Build Status](https://secure.travis-ci.org/yeoman/configstore.svg?branch=master)](http://travis-ci.org/yeoman/configstore)
+
+> Easily load and persist config without having to think about where and how.
+
+Config is stored in a YAML file to make it simple for users to edit the config directly themselves. The file is located in `$XDG_CONFIG_HOME` or `~/.config`. Eg: `~/.config/configstore/id-of-your-choosing.yml`
+
+
+## Usage
+
+```js
+var Configstore = require('configstore');
+var packageName = require('./package').name;
+
+// Init a Configstore instance with an unique ID eg. package name
+// and optionally some default values
+var conf = new Configstore(packageName, { foo: 'bar' });
+
+conf.set('awesome', true);
+console.log(conf.get('awesome'));  // true
+console.log(conf.get('foo'));      // bar
+
+conf.del('awesome');
+console.log(conf.get('awesome'));  // undefined
+```
+
+
+## Documentation
+
+### Methods
+
+#### .set(key, val)
+
+Set an item
+
+#### .get(key)
+
+Get an item
+
+#### .del(key)
+
+Delete an item
+
+### Properties
+
+#### .all
+
+Get all items as an object or replace the current config with an object:
+
+```js
+conf.all = {
+	hello: 'world'
+};
+```
+
+#### .size
+
+Get the item count
+
+#### .path
+
+Get the path to the config file. Can be used to show the user where the config file is located or even better open it for them.

Alternative\nimplementation is a literal copy of standard one located in standalone\nmodule to avoid requiring of `util`. It also has a shim for old\nbrowsers with no `Object.create` support.\n\nWhile keeping you sure you are using standard `inherits`\nimplementation in node.js environment, it allows bundlers such as\n[browserify](https://github.com/substack/node-browserify) to not\ninclude full `util` package to your client code if all you need is\njust `inherits` function. It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n  superclass\n* new version overwrites current prototype while old one preserves any\n  existing fields on it\n",

+# cookie-parser
+
+[![NPM Version][npm-image]][npm-url]
+[![NPM Downloads][downloads-image]][downloads-url]
+[![Build Status][travis-image]][travis-url]
+[![Test Coverage][coveralls-image]][coveralls-url]
+
+Parse `Cookie` header and populate `req.cookies` with an object keyed by the cookie
+names. Optionally you may enable signed cookie support by passing a `secret` string,
+which assigns `req.secret` so it may be used by other middleware.
+
+## Installation
+
+```sh
+$ npm install cookie-parser
+```
+
+## API
+
+```js
+var express      = require('express')
+var cookieParser = require('cookie-parser')
+
+var app = express()
+app.use(cookieParser())
+```
+
+### cookieParser(secret, options)
+
+- `secret` a string used for signing cookies. This is optional and if not specified, will not parse signed cookies.
+- `options` an object that is passed to `cookie.parse` as the second option. See [cookie](https://www.npmjs.org/package/cookie) for more information.
+  - `decode` a function to decode the value of the cookie
+
+### cookieParser.JSONCookie(str)
+
+Parse a cookie value as a JSON cookie. This will return the parsed JSON value if it was a JSON cookie, otherwise it will return the passed value.
+
+### cookieParser.JSONCookies(cookies)
+
+Given an object, this will iterate over the keys and call `JSONCookie` on each value. This will return the same object passed in.
+
+### cookieParser.signedCookie(str, secret)
+
+Parse a cookie value as a signed cookie. This will return the parsed unsigned value if it was a signed cookie and the signature was valid, otherwise it will return the passed value.
+
+### cookieParser.signedCookies(cookies, secret)
+
+Given an object, this will iterate over the keys and check if any value is a signed cookie. If it is a signed cookie and the signature is valid, the key will be deleted from the object and added to the new object that is returned.
+
+## Example
+
+```js
+var express      = require('express')
+var cookieParser = require('cookie-parser')
+
+var app = express()
+app.use(cookieParser())
+
+app.get('/', function(req, res) {
+  console.log("Cookies: ", req.cookies)
+})
+
+app.listen(8080)
+
+// curl command that sends an HTTP request with two cookies
+// curl http://127.0.0.1:8080 --cookie "Cho=Kim;Greet=Hello"
+```

+
+  Simple cookie-based session middleware.
+
+## Semantics
+
+  This module provides "guest" sessions, meaning any visitor will have a session,
+  authenticated or not. If a session is _new_ a `Set-Cookie` will be produced regardless
+  of populating the session.
+
+## Install
+
+```bash
+$ npm install cookie-session
+```
+
+## API
+
+  View counter example:
+
+```js
+var express = require('express')
+var session = require('cookie-session')
+
+var app = express()
+
+app.set('trust proxy', 1) // trust first proxy
+
+app.use(session({
+  keys: ['key1', 'key2']
+}))
+
+app.use(function (req, res, next) {
+  var n = req.session.views || 0
+  req.session.views = ++n
+  res.end(n + ' views')
+})
+
+app.listen(3000)
+```
+
+### Options
+
+  - `name` - The cookie name. Defaults to `express:sess`.
+  - `keys` - Keys with which to sign the cookie. See `signed` in cookie options. Multiple keys allows for using rotating credentials.
+  - `secret` - A string which will be used as single key if `keys` is not found.
+
+  Other options are passed to `cookies.get()` and
+  `cookies.set()` allowing you to control security, domain, path,
+  and signing among other settings.
+
+#### Cookie Options
+
+The options can also contain any of the follow (for the full list, see [cookies module documentation](https://www.npmjs.org/package/cookies#readme):
+
+  - `maxAge`: a number representing the milliseconds from `Date.now()` for expiry
+  - `expires`: a `Date` object indicating the cookie's expiration date (expires at the end of session by default).
+  - `path`: a string indicating the path of the cookie (`/` by default).
+  - `domain`: a string indicating the domain of the cookie (no default).
+  - `secure`: a boolean indicating whether the cookie is only to be sent over HTTPS (`false` by default for HTTP, `true` by default for HTTPS).
+  - `secureProxy`: a boolean indicating whether the cookie is only to be sent over HTTPS (use this if you handle SSL not in your node process).
+  - `httpOnly`: a boolean indicating whether the cookie is only to be sent over HTTP(S), and not made available to client JavaScript (`true` by default).
+  - `signed`: a boolean indicating whether the cookie is to be signed (`false` by default). If this is true, another cookie of the same name with the `.sig` suffix appended will also be sent, with a 27-byte url-safe base64 SHA1 value representing the hash of _cookie-name_=_cookie-value_ against the first [Keygrip](https://github.com/expressjs/keygrip) key. This signature key is used to detect tampering the next time a cookie is received.
+  - `overwrite`: a boolean indicating whether to overwrite previously set cookies of the same name (`false` by default). If this is true, all cookies set during the same request with the same name (regardless of path or domain) are filtered out of the Set-Cookie header when setting this cookie.
+
+### Session.isNew
+
+  Is `true` if the session is new.
+
+### Destroying a session
+
+  To destroy a session simply set it to `null`:
+
+```js
+req.session = null
+```

+Cookies
+=======
+
+[![NPM Version](https://badge.fury.io/js/cookies.svg)](https://badge.fury.io/js/cookies)
+[![Build Status](https://travis-ci.org/expressjs/cookies.svg?branch=master)](https://travis-ci.org/expressjs/cookies)
+
+Cookies is a [node.js](http://nodejs.org/) module for getting and setting HTTP(S) cookies. Cookies can be signed to prevent tampering, using [Keygrip](https://github.com/expressjs/keygrip). It can be used with the built-in node.js HTTP library, or as Connect/Express middleware.
+
+## Requirements
+
+* [node.js](http://nodejs.org/), tested with 0.8 and 0.10
+
+## Install
+
+    $ npm install cookies
+
+## Features
+
+* **Lazy**: Since cookie verification against multiple keys could be expensive, cookies are only verified lazily when accessed, not eagerly on each request.
+
+* **Secure**: All cookies are `httponly` by default, and cookies sent over SSL are `secure` by default. An error will be thrown if you try to send secure cookies over an insecure socket.
+
+* **Unobtrusive**: Signed cookies are stored the same way as unsigned cookies, instead of in an obfuscated signing format. An additional signature cookie is stored for each signed cookie, using a standard naming convention (_cookie-name_`.sig`). This allows other libraries to access the original cookies without having to know the signing mechanism.
+
+* **Agnostic**: This library is optimized for use with [Keygrip](https://github.com/expressjs/keygrip), but does not require it; you can implement your own signing scheme instead if you like and use this library only to read/write cookies. Factoring the signing into a separate library encourages code reuse and allows you to use the same signing library for other areas where signing is needed, such as in URLs.
+
+## API
+
+### cookies = new Cookies( request, response, keys )
+
+This creates a cookie jar corresponding to the current _request_ and _response_. A [Keygrip](https://github.com/expressjs/keygrip) object or an array of keys can optionally be passed as the third argument _keygrip_ to enable cryptographic signing based on SHA1 HMAC, using rotated credentials.
+
+Note that since this only saves parameters without any other processing, it is very lightweight. Cookies are only parsed on demand when they are accessed.
+
+### express.createServer( Cookies.express( keys ) )
+
+This adds cookie support as a Connect middleware layer for use in Express apps, allowing inbound cookies to be read using `req.cookies.get` and outbound cookies to be set using `res.cookies.set`.
+
+### cookies.get( name, [ options ] )
+
+This extracts the cookie with the given name from the `Cookie` header in the request. If such a cookie exists, its value is returned. Otherwise, nothing is returned.
+
+`{ signed: true }` can optionally be passed as the second parameter _options_. In this case, a signature cookie (a cookie of same name ending with the `.sig` suffix appended) is fetched. If no such cookie exists, nothing is returned.
+
+If the signature cookie _does_ exist, the provided [Keygrip](https://github.com/expressjs/keygrip) object is used to check whether the hash of _cookie-name_=_cookie-value_ matches that of any registered key:
+
+* If the signature cookie hash matches the first key, the original cookie value is returned.
+* If the signature cookie hash matches any other key, the original cookie value is returned AND an outbound header is set to update the signature cookie's value to the hash of the first key. This enables automatic freshening of signature cookies that have become stale due to key rotation.
+* If the signature cookie hash does not match any key, nothing is returned, and an outbound header with an expired date is used to delete the cookie.
+
+### cookies.set( name, [ value ], [ options ] )
+
+This sets the given cookie in the response and returns the current context to allow chaining.
+
+If the _value_ is omitted, an outbound header with an expired date is used to delete the cookie.
+
+If the _options_ object is provided, it will be used to generate the outbound cookie header as follows:
+
+* `maxAge`: a number representing the milliseconds from `Date.now()` for expiry
+* `expires`: a `Date` object indicating the cookie's expiration date (expires at the end of session by default).
+* `path`: a string indicating the path of the cookie (`/` by default).
+* `domain`: a string indicating the domain of the cookie (no default).
+* `secure`: a boolean indicating whether the cookie is only to be sent over HTTPS (`false` by default for HTTP, `true` by default for HTTPS).
+* `secureProxy`: a boolean indicating whether the cookie is only to be sent over HTTPS (use this if you handle SSL not in your node process).
+* `httpOnly`: a boolean indicating whether the cookie is only to be sent over HTTP(S), and not made available to client JavaScript (`true` by default).
+* `signed`: a boolean indicating whether the cookie is to be signed (`false` by default). If this is true, another cookie of the same name with the `.sig` suffix appended will also be sent, with a 27-byte url-safe base64 SHA1 value representing the hash of _cookie-name_=_cookie-value_ against the first [Keygrip](https://github.com/expressjs/keygrip) key. This signature key is used to detect tampering the next time a cookie is received.
+* `overwrite`: a boolean indicating whether to overwrite previously set cookies of the same name (`false` by default). If this is true, all cookies set during the same request with the same name (regardless of path or domain) are filtered out of the Set-Cookie header when setting this cookie.
+
+## Example
+
+```javascript
+var http    = require( "http" )
+var Cookies = require( "cookies" )
+
+server = http.createServer( function( req, res ) {
+  var cookies = new Cookies( req, res, keys )
+    , unsigned, signed, tampered
+
+  if ( req.url == "/set" ) {
+    cookies
+      // set a regular cookie
+      .set( "unsigned", "foo", { httpOnly: false } )
+
+      // set a signed cookie
+      .set( "signed", "bar", { signed: true } )
+
+      // mimic a signed cookie, but with a bogus signature
+      .set( "tampered", "baz" )
+      .set( "tampered.sig", "bogus" )
+
+    res.writeHead( 302, { "Location": "/" } )
+    return res.end( "Now let's check." )
+  }
+
+  unsigned = cookies.get( "unsigned" )
+  signed = cookies.get( "signed", { signed: true } )
+  tampered = cookies.get( "tampered", { signed: true } )
+
+  assert.equal( unsigned, "foo" )
+  assert.equal( signed, "bar" )
+  assert.notEqual( tampered, "baz" )
+  assert.equal( tampered, undefined )
+
+  res.writeHead( 200, { "Content-Type": "text/plain" } )
+  res.end(
+    "unsigned expected: foo\n\n" +
+    "unsigned actual: " + unsigned + "\n\n" +
+    "signed expected: bar\n\n" +
+    "signed actual: " + signed + "\n\n" +
+    "tampered expected: undefined\n\n"+
+    "tampered: " + tampered + "\n\n"
+  )
+})
+```

+# debug
+
+  tiny node.js debugging utility modelled after node core's debugging technique.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+ With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` format string goodies you're used to work fine. A unique color is selected per-function for visibility.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command. 
+ 
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+Then, run the program to be debugged as ususal.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+ If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect.compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Browser support
+
+  Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. Somewhere in the code on your page, include:
+
+```js
+window.myDebug = require("debug");
+```
+
+  ("debug" is a global object in the browser so we give this object a different name.) When your page is open in the browser, type the following in the console:
+
+```js
+myDebug.enable("worker:*")
+```
+
+  Refresh the page. Debug output will continue to be sent to the console until it is disabled by typing `myDebug.disable()` in the console.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+### stderr vs stdout
+
+You can set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally:
+
+Example _stderr.js_:
+
+```js
+var debug = require('../');
+var log = debug('app:log');
+
+// by default console.log is used
+log('goes to stdout!');
+
+var error = debug('app:error');
+// set this namespace to log via console.error
+error.log = console.error.bind(console); // don't forget to bind to console!
+error('goes to stderr');
+log('still goes to stdout!');
+
+// set all output to go via console.warn
+// overrides all per-namespace log settings
+debug.log = console.warn.bind(console);
+log('now goes to stderr via console.warn');
+error('still goes to stderr, but via console.warn now');
+```

+- Node/Browser compatible. Published as [`ms`](https://www.npmjs.org/package/ms) in [NPM](nodejs.org/download).
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as
+a number (e.g: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of
+equivalent ms is returned.

+
+Execute a listener when a response is about to write headers.
+
+## Install
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+```js
+var onHeaders = require('on-headers')
+```
+
+### onHeaders(res, listener)
+
+This will add the listener `listener` to fire when headers are emitted for `res`.
+The listener is passed the `response` object as it's context (`this`). Headers are
+considered to be emitted only once, right before they are sent to the client.
+
+When this is called multiple times on the same `res`, the `listener`s are fired
+in the reverse order they were added.
+
+## Examples
+
+```js
+var http = require('http')
+var onHeaders = require('on-headers')
+
+http
+.createServer(onRequest)
+.listen(3000)
+
+function addPoweredBy() {
+  // add if not set by end of request
+  if (!this.getHeader('X-Powered-By')) {
+    this.addHeader('X-Powered-By', 'Node.js')
+  }
+}
+
+function onRequest(req, res) {
+  onHeaders(res, addPoweredBy)
+
+  res.setHeader('Content-Type', 'text/plain')
+  res.end('hello!')
+}
+```

+
+Node.js [CSRF](https://en.wikipedia.org/wiki/Cross-site_request_forgery) protection middleware.
+
+Requires either a session middleware or [cookie-parser](https://www.npmjs.com/package/cookie-parser) to be initialized first.
+- [express-session](https://www.npmjs.com/package/express-session)
+- [cookie-session](https://www.npmjs.com/package/cookie-session)
+
+If you have questions on how this module is implemented, please read
+[Understanding CSRF](https://github.com/pillarjs/understanding-csrf).
+
+## Installation
+
+```sh
+$ npm install csurf
+```
+
+## API
+
+```js
+var csurf = require('csurf')
+```
+
+### csurf([options])
+
+Create a middleware for CSRF token creation and validation. This middleware
+adds a `req.csrfToken()` function to make a token which should be added to
+requests which mutate state, within a hidden form field, query-string etc.
+This token is validated against the visitor's session or csrf cookie.
+
+#### Options
+
+The `csurf` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### cookie
+
+Determines if the token secret for the user should be stored in a cookie
+(when set to `true` or an object, requires a cookie parsing module) or in
+`req.session` (when set to `false`, provided by another module). Defaults
+to `false`.
+
+When set to an object, cookie storage of the secret is enabled and the
+object contains options for this functionality (when set to `true`, the
+defaults for the options are used). The options may contain any of the
+following keys:
+
+  - `key` - the name of the cookie to use to store the token secret
+    (defaults to `'_csrf'`).
+  - `path` - the path of the cookie (defaults to `'/'`).
+  - any other [res.cookie](http://expressjs.com/4x/api.html#res.cookie)
+    option can be set.
+
+##### ignoreMethods
+
+An array of the methods for which CSRF token checking will disabled.
+Defaults to `['GET', 'HEAD', 'OPTIONS']`.
+
+##### value
+
+Provide a function that the middleware will invoke to read the token from
+the request for validation. The function is called as `value(req)` and is
+expected to return the token as a string.
+
+The default value is a function that reads the token from the following
+locations, in order:
+
+  - `req.body._csrf` - typically generated by the `body-parser` module.
+  - `req.query._csrf` - a built-in from Express.js to read from the URL
+    query string.
+  - `req.headers['csrf-token']` - the `CSRF-Token` HTTP request header.
+  - `req.headers['xsrf-token']` - the `XSRF-Token` HTTP request header.
+  - `req.headers['x-csrf-token']` - the `X-CSRF-Token` HTTP request header.
+  - `req.headers['x-xsrf-token']` - the `X-XSRF-Token` HTTP request header.
+
+## Example
+
+### Simple express example
+
+The following is an example of some server-side code that generates a form
+that requires a CSRF token to post back.
+
+```js
+var cookieParser = require('cookie-parser')
+var csrf = require('csurf')
+var bodyParser = require('body-parser')
+var express = require('express')
+
+// setup route middlewares
+var csrfProtection = csrf({ cookie: true })
+var parseForm = bodyparser.urlencoded({ extended: false })
+
+// create express app
+var app = express()
+
+// parse cookies
+app.use(cookieParser())
+
+app.get('/form', csrfProtection, function(req, res) {
+  // pass the csrfToken to the view
+  res.render('send', { csrfToken: req.csrfToken() })
+})
+
+app.post('/process', parseForm, csrfProtection, function(req, res) {
+  res.send('data is being processed')
+})
+```
+
+Inside the view (depending on your template language; handlebars-style
+is demonstrated here), set the `csrfToken` value as the value of a hidden
+input field named `_csrf`:
+
+```html
+<form action="/process" method="POST">
+  <input type="hidden" name="_csrf" value="{{csrfToken}}">
+  
+  Favorite color: <input type="text" name="favoriteColor">
+  <button type="submit">Submit</button>
+</form>
+```
+
+### Custom error handling
+
+When the CSRF token validation fails, an error is thrown that has
+`err.code === 'EBADCSRFTOKEN'`. This can be used to display custom
+error messages.
+
+```js
+var bodyParser = require('body-parser')
+var cookieParser = require('cookie-parser')
+var csrf = require('csurf')
+var express = require('express')
+
+var app = express()
+app.use(bodyParser.urlencoded({ extended: false }))
+app.use(cookieParser())
+app.use(csrf({ cookie: true }))
+
+// error handler
+app.use(function (err, req, res, next) {
+  if (err.code !== 'EBADCSRFTOKEN') return next(err)
+
+  // handle CSRF token errors here
+  res.status(403)
+  res.send('form tampered with')
+})
+```

+# CSRF
+
+[![NPM Version][npm-image]][npm-url]
+[![NPM Downloads][downloads-image]][downloads-url]

+
+Logic behind CSRF token creation and verification.
+Read [Understanding-CSRF](https://github.com/pillarjs/understanding-csrf) for more information on CSRF.
+Use this module to create custom CSRF middleware and what not.
+
+### Install
+
+```bash
+$ npm install csrf
+```
+
+## API
+
+```js
+var csrf = require('csrf')(options)
+
+var secret = csrf.secretSync()
+var token  = csrf.create(secret)
+var valid  = csrf.verify(secret, token)
+```
+
+### Options
+
+- `secretLength: 24` - the byte length of the secret key
+- `saltLength: 8` - the string length of the salt
+- `tokensize: (secret, salt) => token` - a custom token creation function
+
+#### csrf.secret([cb])
+
+Asynchronously create a new `secret` of length `secretLength`.
+If `cb` is not defined, a promise is returned.
+You don't have to use this.
+
+```js
+csrf.secret().then(function (secret) {
+
+})
+
+csrf.secret(function (err, secret) {
+
+})
+```
+
+#### var secret = csrf.secretSync()
+
+Synchronous version of `csrf.secret()`
+
+#### var token = csrf.create(secret)
+
+Create a CSRF token based on a `secret`.
+This is the token you pass to clients.
+
+#### var valid = csrf.verify(secret, token)
+
+Check whether a CSRF token is valid based on a `secret`.
+If it's not valid, you should probably throw a `403` error.

+# RNDM
+
+Random string generator.
+Basically `Math.random().toString(36).slice(2)`,
+but with both upper and lower case letters and arbitrary lengths.
+Useful for creating fast, not cryptographically secure salts.
+
+## API
+
+```js
+// base62 by default
+var rndm = require('rndm')
+var salt = rndm(16)
+```
+
+### var salt = rndm(length)
+
+### var salt = rndm.base62(length)
+
+### var salt = rndm.base36(length)
+
+### var salt = rndm.base10(length)
+
+### var random = rndm.create(characters)
+
+Create a new random generator with custom characters.

+# scmp [![Build Status](https://travis-ci.org/freewil/scmp.svg?branch=master)](https://travis-ci.org/freewil/scmp)
+
+Safe, constant-time comparison of strings.
+
+## Install
+
+```
+npm install scmp
+```
+
+## Why?
+
+To minimize vulnerability against [timing attacks](http://codahale.com/a-lesson-in-timing-attacks/).
+
+## Examples
+
+```js
+var scmp = require('scmp');
+
+var hash      = 'e727d1464ae12436e899a726da5b2f11d8381b26';
+var givenHash = 'e727e1b80e448a213b392049888111e1779a52db';
+
+if (scmp(hash, givenHash)) {
+  console.log('good hash');
+} else {
+  console.log('bad hash');
+}
+
+```

+
+URL and cookie safe UIDs
+
+Create cryptographically secure UIDs safe for both cookie and URL usage.
+This is in contrast to modules such as [rand-token](https://www.npmjs.com/package/rand-token)
+and [uid2](https://www.npmjs.com/package/uid2) whose UIDs are actually skewed
+due to the use of `%` and unnecessarily truncate the UID.
+Use this if you could still use UIDs with `-` and `_` in them.
+
+## Installation
+
+```sh
+$ npm install uid-safe
+```
+
+## API
+
+```js
+var uid = require('uid-safe')
+```
+
+### uid(byteLength, callback)
+
+Asynchronously create a UID with a specific byte length. Because `base64`
+encoding is used underneath, this is not the string length. For example,
+to create a UID of length 24, you want a byte length of 18.
+
+```js
+uid(18, function (err, string) {
+  if (err) throw err
+  // do something with the string
+})
+```
+
+### uid(byteLength)
+
+Asynchronously create a UID with a specific byte length and return a
+`Promise`.
+
+**To use promises, you must either install [bluebird](https://www.npmjs.com/package/bluebird)
+or use a version of Node.js that has native promises, otherwise an
+error will be thrown.**
+
+```js
+uid(18).then(function (string) {
+  // do something with the string
+})
+```
+
+### uid.sync(byteLength)
+
+A synchronous version of above.
+
+```js
+var string = uid.sync(18)
+```

+Use either `bluebird` or the native `Promise` implementation.
+If no implementation is found, an error will be thrown:
+
+```js
+var Promise = require('native-or-bluebird');
+```
+
+The goal of this library is to be able to eventually remove this line
+from your code and use native `Promise`s, allowing you to
+to write future-compatible code with ease.
+You should install `bluebird` in your libraries for maximum compatibility.
+
+If you do not want an error to be thrown,
+`require()` the `Promise` implementation directly.
+If no implementation is found, `undefined` will be returned.
+
+```js
+var Promise = require('native-or-bluebird/promise');
+if (Promise) // do stuff with promises
+```

Alternative\nimplementation is a literal copy of standard one located in standalone\nmodule to avoid requiring of `util`. It also has a shim for old\nbrowsers with no `Object.create` support.\n\nWhile keeping you sure you are using standard `inherits`\nimplementation in node.js environment, it allows bundlers such as\n[browserify](https://github.com/substack/node-browserify) to not\ninclude full `util` package to your client code if all you need is\njust `inherits` function. It worth, because browser shim for `util`\npackage is large and `inherits` is often the single function you need\nfrom it.\n\nIt's recommended to use this package instead of\n`require('util').inherits` for any code that has chances to be used\nnot only in node.js but in browser too.\n\n## usage\n\n```js\nvar inherits = require('inherits');\n// then use exactly as the standard one\n```\n\n## note on version ~1.0\n\nVersion ~1.0 had completely different motivation and is not compatible\nneither with 2.0 nor with standard node.js `inherits`.\n\nIf you are using version ~1.0 and planning to switch to ~2.0, be\ncareful:\n\n* new version uses `super_` instead of `super` for referencing\n  superclass\n* new version overwrites current prototype while old one preserves any\n  existing fields on it\n",

+
+HTTP status utility for node.
+
+## API
+
+```js
+var status = require('statuses');
+```
+
+### var code = status(Integer || String)
+
+If `Integer` or `String` is a valid HTTP code or status message, then the appropriate `code` will be returned. Otherwise, an error will be thrown.
+
+```js
+status(403) // => 'Forbidden'
+status('403') // => 'Forbidden'
+status('forbidden') // => 403
+status('Forbidden') // => 403
+status(306) // throws, as it's not supported by node.js
+```
+
+### status.codes
+
+Returns an array of all the status codes as `Integer`s.
+
+### var msg = status[code]
+
+Map of `code` to `status message`. `undefined` for invalid `code`s.
+
+```js
+status[404] // => 'Not Found'
+```
+
+### var code = status[msg]
+
+Map of `status message` to `code`. `msg` can either be title-cased or lower-cased. `undefined` for invalid `status message`s.
+
+```js
+status['not found'] // => 404
+status['Not Found'] // => 404
+```
+
+### status.redirect[code]
+
+Returns `true` if a status code is a valid redirect status.
+
+```js
+status.redirect[200] // => undefined
+status.redirect[301] // => true
+```
+
+### status.empty[code]
+
+Returns `true` if a status code expects an empty body.
+
+```js
+status.empty[200] // => undefined
+status.empty[204] // => true
+status.empty[304] // => true
+```
+
+### status.retry[code]
+
+Returns `true` if you should retry the rest.
+
+```js
+status.retry[501] // => undefined
+status.retry[503] // => true
+```
+
+### statuses/codes.json
+
+```js
+var codes = require('statuses/codes.json');
+```
+
+This is a JSON file of the status codes
+taken from `require('http').STATUS_CODES`.
+This is saved so that codes are consistent even in older node.js versions.
+For example, `308` will be added in v0.12.
+
+## Adding Status Codes
+
+The status codes are primarily sourced from http://www.iana.org/assignments/http-status-codes/http-status-codes-1.csv.
+Additionally, custom codes are added from http://en.wikipedia.org/wiki/List_of_HTTP_status_codes.
+These are added manually in the `lib/*.json` files.
+If you would like to add a status code, add it to the appropriate JSON file.
+
+To rebuild `codes.json`, run the following:
+
+```bash
+# update src/iana.json
+npm run update
+# build codes.json
+npm run build
+```

This method accepts either comma separated globbing patterns or an array of globbing patterns. Paths matching patterns that begin with `!` will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant.\n\n```js\nglobule.find(patterns [, options])\n```\n\nThe `options` object supports all [glob][] library options, along with a few extras. These are the most commonly used:\n\n* `filter` Either a valid [fs.Stats method name](http://nodejs.org/docs/latest/api/fs.html#fs_class_fs_stats) or a function that will be passed the matched `src` filepath and `options` object as arguments. This function should return a `Boolean` value.\n* `nonull` Retain globbing patterns in result set even if they fail to match files.\n* `matchBase` Patterns without slashes will match just the basename part. Eg. this makes `*.js` work like `**/*.js`.\n* `srcBase` Patterns will be matched relative to the specified path instead of the current working directory. This is a synonym for `cwd`.\n* `prefixBase` Any specified `srcBase` will be prefixed to all returned filepaths.\n\n[glob]: https://github.com/isaacs/node-glob\n\n### globule.match\nMatch one or more globbing patterns against one or more file paths. Returns a uniqued array of all file paths that match any of the specified globbing patterns. Both the `patterns` and `filepaths` arguments can be a single string or array of strings. Paths matching patterns that begin with `!` will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant.\n\n```js\ngrunt.file.match(patterns, filepaths [, options])\n```\n\n### globule.isMatch\nThis method contains the same signature and logic as the `globule.match` method, but returns `true` if any files were matched, otherwise `false`.\n\n```js\ngrunt.file.isMatch(patterns, filepaths [, options])\n```\n\n### globule.mapping\nGiven a set of source file paths, returns an array of src-dest file mapping objects. Both src and dest paths may be renamed, depending on the options specified.\n\n```js\nglobule.mapping(filepaths [, options])\n```\n\nIn addition to the options the `globule.find` method supports, the options object also supports these properties:\n\n* `srcBase` The directory from which patterns are matched. Any string specified as `srcBase` is effectively stripped from the beginning of all matched paths.\n* `destBase` The specified path is prefixed to all `dest` filepaths.\n* `ext` Remove anything after (and including) the first `.` in the destination path, then append this value.\n* `extDot` Change the behavior of `ext`, `\"first\"` and `\"last\"` will remove anything after the first or last `.` in the destination filename, respectively. Defaults to `\"first\"`.\n* `flatten` Remove the path component from all matched src files. The src file path is still joined to the specified destBase.\n* `rename` If specified, this function will be responsible for returning the final `dest` filepath. By default, it flattens paths (if specified), changes extensions (if specified) and joins the matched path to the `destBase`.\n\n### globule.findMapping\nThis method is a convenience wrapper around the `globule.find` and `globule.mapping` methods.\n\n```js\nglobule.findMapping(patterns [, options])\n```\n\n\n## Examples\n\nGiven the files `foo/a.js` and `foo/b.js`:\n\n### srcBase and destBase\n\n```js\nglobule.find(\"foo/*.js\")\n// [\"foo/a.js\", \"foo/b.js\"]\n\nglobule.find(\"*.js\", {srcBase: \"foo\"})\n// [\"a.js\", \"b.js\"]\n\nglobule.find(\"*.js\", {srcBase: \"foo\", prefixBase: true})\n// [\"foo/a.js\", \"foo/b.js\"]\n```\n\n```js\nglobule.findMapping(\"foo/*.js\")\n// [{src: \"foo/a.js\", dest: \"foo/a.js\"}, {src: \"foo/b.js\", dest: \"foo/b.js\"}]\n\nglobule.findMapping(\"foo/*.js\", {destBase: \"bar\"})\n// [{src: \"foo/a.js\", dest: \"bar/foo/a.js\"}, {src: \"foo/b.js\", dest: \"bar/foo/b.js\"}]\n\nglobule.findMapping(\"*.js\", {srcBase: \"foo\", destBase: \"bar\"})\n// [{src: \"foo/a.js\", dest: \"bar/a.js\"}, {src: \"foo/b.js\", dest: \"bar/b.js\"}]\n```\n\n```js\nglobule.mapping([\"foo/a.js\", \"foo/b.js\"])\n// [{src: \"foo/a.js\", dest: \"foo/a.js\"}, {src: \"foo/b.js\", dest: \"foo/b.js\"}]\n\nglobule.mapping([\"foo/a.js\", \"foo/b.js\"], {destBase: \"bar\"})\n// [{src: \"foo/a.js\", dest: \"bar/foo/a.js\"}, {src: \"foo/b.js\", dest: \"bar/foo/b.js\"}]\n\nglobule.mapping([\"a.js\", \"b.js\"], {srcBase: \"foo\", destBase: \"bar\"})\n// [{src: \"foo/a.js\", dest: \"bar/a.js\"}, {src: \"foo/b.js\", dest: \"bar/b.js\"}]\n```\n\n## Contributing\nIn lieu of a formal styleguide, take care to maintain the existing coding style.

+  "readme": "# faye-websocket\n\n* Travis CI build: [<img src=\"https://secure.travis-ci.org/faye/faye-websocket-node.png\" />](http://travis-ci.org/faye/faye-websocket-node)\n* Autobahn tests: [server](http://faye.jcoglan.com/autobahn/servers/), [client](http://faye.jcoglan.com/autobahn/clients/)\n\nThis is a robust, general-purpose WebSocket implementation extracted from the\n[Faye](http://faye.jcoglan.com) project. It provides classes for easily building\nWebSocket servers and clients in Node. It does not provide a server itself, but\nrather makes it easy to handle WebSocket connections within an existing\n[Node](http://nodejs.org/) application. It does not provide any abstraction\nother than the standard [WebSocket API](http://dev.w3.org/html5/websockets/).\n\nIt also provides an abstraction for handling [EventSource](http://dev.w3.org/html5/eventsource/)\nconnections, which are one-way connections that allow the server to push data to\nthe client. They are based on streaming HTTP responses and can be easier to\naccess via proxies than WebSockets.\n\nThe server-side socket can process [draft-75](http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-75),\n[draft-76](http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-76),\n[hybi-07](http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-07)\nand later versions of the protocol. It selects protocol versions automatically,\nsupports both `text` and `binary` messages, and transparently handles `ping`,\n`pong`, `close` and fragmented messages.\n\n\n## Handling WebSocket connections in Node\n\nYou can handle WebSockets on the server side by listening for HTTP Upgrade\nrequests, and creating a new socket for the request. This socket object exposes\nthe usual WebSocket methods for receiving and sending messages. For example this\nis how you'd implement an echo server:\n\n```js\nvar WebSocket = require('faye-websocket'),\n    http      = require('http');\n\nvar server = http.createServer();\n\nserver.addListener('upgrade', function(request, socket, head) {\n  var ws = new WebSocket(request, socket, head);\n  \n  ws.onmessage = function(event) {\n    ws.send(event.data);\n  };\n  \n  ws.onclose = function(event) {\n    console.log('close', event.code, event.reason);\n    ws = null;\n  };\n});\n\nserver.listen(8000);\n```\n\nNote that under certain circumstances (notably a draft-76 client connecting\nthrough an HTTP proxy), the WebSocket handshake will not be complete after you\ncall `new WebSocket()` because the server will not have received the entire\nhandshake from the client yet. In this case, calls to `ws.send()` will buffer\nthe message in memory until the handshake is complete, at which point any\nbuffered messages will be sent to the client.\n\nIf you need to detect when the WebSocket handshake is complete, you can use the\n`onopen` event.\n\nIf the connection's protocol version supports it, you can call `ws.ping()` to\nsend a ping message and wait for the client's response. This method takes a\nmessage string, and an optional callback that fires when a matching pong message\nis received. It returns `true` iff a ping message was sent. If the client does\nnot support ping/pong, this method sends no data and returns `false`.\n\n```js\nws.ping('Mic check, one, two', function() {\n  // fires when pong is received\n});\n```\n\n\n## Using the WebSocket client\n\nThe client supports both the plain-text `ws` protocol and the encrypted `wss`\nprotocol, and has exactly the same interface as a socket you would use in a web\nbrowser. On the wire it identifies itself as hybi-13.\n\n```js\nvar WebSocket = require('faye-websocket'),\n    ws        = new WebSocket.Client('ws://www.example.com/');\n\nws.onopen = function(event) {\n  console.log('open');\n  ws.send('Hello, world!');\n};\n\nws.onmessage = function(event) {\n  console.log('message', event.data);\n};\n\nws.onclose = function(event) {\n  console.log('close', event.code, event.reason);\n  ws = null;\n};\n```\n\n\n## Subprotocol negotiation\n\nThe WebSocket protocol allows peers to select and identify the application\nprotocol to use over the connection. On the client side, you can set which\nprotocols the client accepts by passing a list of protocol names when you\nconstruct the socket:\n\n```js\nvar ws = new WebSocket.Client('ws://www.example.com/', ['irc', 'amqp']);\n```\n\nOn the server side, you can likewise pass in the list of protocols the server\nsupports after the other constructor arguments:\n\n```js\nvar ws = new WebSocket(request, socket, head, ['irc', 'amqp']);\n```\n\nIf the client and server agree on a protocol, both the client- and server-side\nsocket objects expose the selected protocol through the `ws.protocol` property.\nIf they cannot agree on a protocol to use, the client closes the connection.\n\n\n## WebSocket API\n\nThe WebSocket API consists of several event handlers and a method for sending\nmessages.\n\n* <b><tt>onopen</tt></b> fires when the socket connection is established. Event\n  has no attributes.\n* <b><tt>onerror</tt></b> fires when the connection attempt fails. Event has no\n  attributes.\n* <b><tt>onmessage</tt></b> fires when the socket receives a message. Event has\n  one attribute, <b><tt>data</tt></b>, which is either a `String` (for text\n  frames) or a `Buffer` (for binary frames).\n* <b><tt>onclose</tt></b> fires when either the client or the server closes the\n  connection. Event has two optional attributes, <b><tt>code</tt></b> and\n  <b><tt>reason</tt></b>, that expose the status code and message sent by the\n  peer that closed the connection.\n* <b><tt>send(message)</tt></b> accepts either a `String` or a `Buffer` and\n  sends a text or binary message over the connection to the other peer.\n* <b><tt>close(code, reason)</tt></b> closes the connection, sending the given\n  status code and reason text, both of which are optional.\n* <b><tt>protocol</tt></b> is a string (which may be empty) identifying the\n  subprotocol the socket is using.\n\n\n## Handling EventSource connections in Node\n\nEventSource connections provide a very similar interface, although because they\nonly allow the server to send data to the client, there is no `onmessage` API.\nEventSource allows the server to push text messages to the client, where each\nmessage has an optional event-type and ID.\n\n```js\nvar WebSocket   = require('faye-websocket'),\n    EventSource = WebSocket.EventSource,\n    http        = require('http');\n\nvar server = http.createServer();\n\nserver.addListener('request', function(request, response) {\n  if (EventSource.isEventSource(request)) {\n    var es = new EventSource(request, response);\n    console.log('open', es.url, es.lastEventId);\n    \n    // Periodically send messages\n    var loop = setInterval(function() { es.send('Hello') }, 1000);\n    \n    es.onclose = function() {\n      clearInterval(loop);\n      es = null;\n    };\n  \n  } else {\n    // Normal HTTP request\n    response.writeHead(200, {'Content-Type': 'text/plain'});\n    response.write('Hello');\n    response.end();\n  }\n});\n\nserver.listen(8000);\n```\n\nThe `send` method takes two optional parameters, `event` and `id`. The default\nevent-type is `'message'` with no ID. For example, to send a `notification`\nevent with ID `99`:\n\n```js\nes.send('Breaking News!', {event: 'notification', id: '99'});\n```\n\nThe `EventSource` object exposes the following properties:\n\n* <b><tt>url</tt></b> is a string containing the URL the client used to create\n  the EventSource.\n* <b><tt>lastEventId</tt></b> is a string containing the last event ID\n  received by the client. You can use this when the client reconnects after a\n  dropped connection to determine which messages need resending.\n\nWhen you initialize an EventSource with ` new EventSource()`, you can pass\nconfiguration options after the `response` parameter. Available options are:\n\n* <b><tt>retry</tt></b> is a number that tells the client how long (in seconds)\n  it should wait after a dropped connection before attempting to reconnect.\n* <b><tt>ping</tt></b> is a number that tells the server how often (in seconds)\n  to send 'ping' packets to the client to keep the connection open, to defeat\n  timeouts set by proxies. The client will ignore these messages.\n\nFor example, this creates a connection that pings every 15 seconds and is\nretryable every 10 seconds if the connection is broken:\n\n```js\nvar es = new EventSource(request, response, {ping: 15, retry: 10});\n```\n\nYou can send a ping message at any time by calling `es.ping()`. Unlike WebSocket,\nthe client does not send a response to this; it is merely to send some data over\nthe wire to keep the connection alive.\n\n\n## License\n\n(The MIT License)\n\nCopyright (c) 2009-2013 James Coglan\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of\nthis software and associated documentation files (the 'Software'), to deal in\nthe Software without restriction, including without limitation the rights to use,\ncopy, modify, merge, publish, distribute, sublicense, and/or sell copies of the\nSoftware, and to permit persons to whom the Software is furnished to do so,\nsubject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS\nFOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

+argparse
+========
+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.png?branch=master)](http://travis-ci.org/nodeca/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB.** Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4
+{ foo: '3', bar: '4' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({paramters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supportied yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument([names or flags], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flags``` - Either a name or a list of option strings, e.g. foo or -f, --foo.
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+# Underscore.string [![Build Status](https://secure.travis-ci.org/epeli/underscore.string.png?branch=master)](http://travis-ci.org/epeli/underscore.string) #
+
+
+
+Javascript lacks complete string manipulation operations.
+This an attempt to fill that gap. List of build-in methods can be found
+for example from [Dive Into JavaScript][d].
+
+[d]: http://www.diveintojavascript.com/core-javascript-reference/the-string-object
+
+
+As name states this an extension for [Underscore.js][u] (and [Lo-Dash](http://lodash.com/)), but it can be used
+independently from **_s**-global variable. But with Underscore.js you can
+use Object-Oriented style and chaining:
+
+[u]: http://underscorejs.org/
+
+```javascript
+_("   epeli  ").chain().trim().capitalize().value()
+=> "Epeli"
+```
+
+## Download ##
+
+  * [Development version](https://raw.github.com/epeli/underscore.string/master/lib/underscore.string.js) *Uncompressed with Comments 18kb*
+  * [Production version](https://github.com/epeli/underscore.string/raw/master/dist/underscore.string.min.js) *Minified 7kb*
+
+
+## Node.js installation ##
+
+**npm package**
+
+    npm install underscore.string
+
+**Standalone usage**:
+
+```javascript
+var _s = require('underscore.string');
+```
+
+**Integrate with Underscore.js**:
+
+```javascript
+var _  = require('underscore');
+
+// Import Underscore.string to separate object, because there are conflict functions (include, reverse, contains)
+_.str = require('underscore.string');
+
+// Mix in non-conflict functions to Underscore namespace if you want
+_.mixin(_.str.exports());
+
+// All functions, include conflict, will be available through _.str object
+_.str.include('Underscore.string', 'string'); // => true
+```
+
+**Or Integrate with Underscore.js without module loading**
+
+Run the following expression after Underscore.js and Underscore.string are loaded
+```javascript
+// _.str becomes a global variable if no module loading is detected
+// Mix in non-conflict functions to Underscore namespace
+_.mixin(_.str.exports());
+```
+
+## String Functions ##
+
+For availability of functions in this way you need to mix in Underscore.string functions:
+
+```javascript
+_.mixin(_.string.exports());
+```
+
+otherwise functions from examples will be available through _.string or _.str objects:
+
+```javascript
+_.str.capitalize('epeli')
+=> "Epeli"
+```
+
+**numberFormat** _.numberFormat(number, [ decimals=0, decimalSeparator='.', orderSeparator=','])
+
+Formats the numbers.
+
+```javascript
+_.numberFormat(1000, 2)
+=> "1,000.00"
+
+_.numberFormat(123456789.123, 5, '.', ',')
+=> "123,456,789.12300"
+```
+
+
+**levenshtein** _.levenshtein(string1, string2)
+
+Calculates [Levenshtein distance][ld] between two strings.
+[ld]: http://en.wikipedia.org/wiki/Levenshtein_distance
+
+```javascript
+_.levenshtein('kitten', 'kittah')
+=> 2
+```
+
+**capitalize** _.capitalize(string)
+
+Converts first letter of the string to uppercase.
+
+```javascript
+_.capitalize("foo Bar")
+=> "Foo Bar"
+```
+
+**chop** _.chop(string, step)
+
+```javascript
+_.chop('whitespace', 3)
+=> ['whi','tes','pac','e']
+```
+
+**clean** _.clean(str)
+
+Compress some whitespaces to one.
+
+```javascript
+_.clean(" foo    bar   ")
+=> 'foo bar'
+```
+
+**chars** _.chars(str)
+
+```javascript
+_.chars('Hello')
+=> ['H','e','l','l','o']
+```
+
+**swapCase** _.swapCase(str)
+
+Returns a copy of the string in which all the case-based characters have had their case swapped.
+
+```javascript
+_.swapCase('hELLO')
+=> 'Hello'
+```
+
+**include** available only through _.str object, because Underscore has function with the same name.
+
+```javascript
+_.str.include("foobar", "ob")
+=> true
+```
+
+(removed) **includes** _.includes(string, substring)
+
+Tests if string contains a substring.
+
+```javascript
+_.includes("foobar", "ob")
+=> true

+
+## Roadmap ##
+
+Any suggestions or bug reports are welcome. Just email me or more preferably open an issue.
+
+#### Problems
+
+We lose two things for `include` and `reverse` methods from `_.string`:
+
+* Calls like `_('foobar').include('bar')` aren't available;
+* Chaining isn't available too.
+
+But if you need this functionality you can create aliases for conflict functions which will be convenient for you:
+
+```javascript
+_.mixin({
+    includeString: _.str.include,
+    reverseString: _.str.reverse
+})
+
+// Now wrapper calls and chaining are available.
+_('foobar').chain().reverseString().includeString('rab').value()
+```
+
+#### Standalone Usage
+
+If you are using Underscore.string without Underscore. You also have `_.string` namespace for it and `_.str` alias
+But of course you can just reassign `_` variable with `_.string`
+
+```javascript
+_ = _.string
+```
+

+```
+
+and all non-conflict Underscore.string functions will be available through Underscore object.
+Also function `includes` has been removed, you should replace this function by `_.str.include`

+
+[Passport](http://passportjs.org/) strategy for authenticating with a username
+and password.
+
+This module lets you authenticate using a username and password in your Node.js
+applications.  By plugging into Passport, local authentication can be easily and
+unobtrusively integrated into any application or framework that supports
+[Connect](http://www.senchalabs.org/connect/)-style middleware, including
+[Express](http://expressjs.com/).
+
+## Install
+
+    $ npm install passport-local
+
+## Usage
+
+#### Configure Strategy
+
+The local authentication strategy authenticates users using a username and
+password.  The strategy requires a `verify` callback, which accepts these
+credentials and calls `done` providing a user.
+
+    passport.use(new LocalStrategy(
+      function(username, password, done) {
+        User.findOne({ username: username }, function (err, user) {
+          if (err) { return done(err); }
+          if (!user) { return done(null, false); }
+          if (!user.verifyPassword(password)) { return done(null, false); }
+          return done(null, user);
+        });
+      }
+    ));
+
+#### Authenticate Requests
+
+Use `passport.authenticate()`, specifying the `'local'` strategy, to
+authenticate requests.
+
+For example, as route middleware in an [Express](http://expressjs.com/)
+application:
+
+    app.post('/login', 
+      passport.authenticate('local', { failureRedirect: '/login' }),
+      function(req, res) {
+        res.redirect('/');
+      });
+

+
+For complete, working examples, refer to the multiple [examples](https://github.com/jaredhanson/passport-local/tree/master/examples) included.
+
+## Tests

+ *
+ * The local authentication strategy authenticates requests based on the
+ * credentials submitted through an HTML-based login form.
+ *
+ * Applications must supply a `verify` callback which accepts `username` and
+ * `password` credentials, and then calls the `done` callback supplying a
+ * `user`, which should be set to `false` if the credentials are not valid.
+ * If an exception occured, `err` should be set.
+ *
+ * Optionally, `options` can be used to change the fields in which the
+ * credentials are found.
+ *
+ * Options:
+ *   - `usernameField`  field name where the username is found, defaults to _username_
+ *   - `passwordField`  field name where the password is found, defaults to _password_
+ *   - `passReqToCallback`  when `true`, `req` is the first argument to the verify callback (default: `false`)
+ *
+ * Examples:
+ *
+ *     passport.use(new LocalStrategy(
+ *       function(username, password, done) {

+
+
+An abstract class implementing [Passport](http://passportjs.org/)'s strategy
+API.
+
+## Install
+
+    $ npm install passport-strategy
+
+## Usage
+
+This module exports an abstract `Strategy` class that is intended to be
+subclassed when implementing concrete authentication strategies.  Once
+implemented, such strategies can be used by applications that utilize Passport
+middleware for authentication.
+
+#### Subclass Strategy
+
+Create a new `CustomStrategy` constructor which inherits from `Strategy`:
+
+```javascript
+var util = require('util')
+  , Strategy = require('passport-strategy');
+
+function CustomStrategy(...) {
+  Strategy.call(this);
+}
+
+util.inherits(CustomStrategy, Strategy);
+```
+
+#### Implement Authentication
+
+Implement `autheticate()`, performing the necessary operations required by the
+authentication scheme or protocol being implemented.
+
+```javascript
+CustomStrategy.prototype.authenticate = function(req, options) {
+  // TODO: authenticate request
+}
+```
+
+## Tests
+
+    $ npm install
+    $ npm test

+# node-uuid
+
+Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.
+
+Features:
+
+* Generate RFC4122 version 1 or version 4 UUIDs
+* Runs in node.js and all browsers.
+* Registered as a [ComponentJS](https://github.com/component/component) [component](https://github.com/component/component/wiki/Components) ('broofa/node-uuid').
+* Cryptographically strong random # generation on supporting platforms
+* 1.1K minified and gzip'ed  (Want something smaller?  Check this [crazy shit](https://gist.github.com/982883) out! )
+* [Annotated source code](http://broofa.github.com/node-uuid/docs/uuid.html)
+* Comes with a Command Line Interface for generating uuids on the command line
+
+## Getting Started
+
+Install it in your browser:
+
+```html
+<script src="uuid.js"></script>
+```
+
+Or in node.js:
+
+```
+npm install node-uuid
+```
+
+```javascript
+var uuid = require('node-uuid');
+```
+
+Then create some ids ...
+
+```javascript
+// Generate a v1 (time-based) id
+uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+
+// Generate a v4 (random) id
+uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'
+```
+
+## API
+
+### uuid.v1([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v1 (timestamp-based) UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID.  See note 1.
+  * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence.  Default: An internally maintained clockseq is used.
+  * `msecs` - (Number | Date) Time in milliseconds since unix Epoch.  Default: The current time is used.
+  * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Notes:
+
+1. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v1({
+  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
+  clockseq: 0x1234,
+  msecs: new Date('2011-11-01').getTime(),
+  nsecs: 5678
+});   // -> "710b962e-041c-11e1-9234-0123456789ab"
+```
+
+Example: In-place generation of two binary IDs
+
+```javascript

+
+### uuid.v4([`options` [, `buffer` [, `offset`]]])
+
+Generate and return a RFC4122 v4 UUID.
+
+* `options` - (Object) Optional uuid state to apply. Properties may include:
+
+  * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values
+  * `rng` - (Function) Random # generator to use.  Set to one of the built-in generators - `uuid.mathRNG` (all platforms), `uuid.nodeRNG` (node.js only), `uuid.whatwgRNG` (WebKit only) - or a custom function that returns an array[16] of byte values.
+
+* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
+* `offset` - (Number) Starting index in `buffer` at which to begin writing.
+
+Returns `buffer`, if specified, otherwise the string form of the UUID
+
+Example: Generate string UUID with fully-specified options
+
+```javascript
+uuid.v4({
+  random: [
+    0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,
+    0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36
+  ]
+});
+// -> "109156be-c4fb-41ea-b1b4-efe1671c5836"
+```
+
+Example: Generate two IDs in a single buffer
+
+```javascript
+var buffer = new Array(32); // (or 'new Buffer' in node.js)
+uuid.v4(null, buffer, 0);
+uuid.v4(null, buffer, 16);
+```
+
+### uuid.parse(id[, buffer[, offset]])
+### uuid.unparse(buffer[, offset])
+
+Parse and unparse UUIDs
+
+  * `id` - (String) UUID(-like) string
+  * `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written. Default: A new Array or Buffer is used
+  * `offset` - (Number) Starting index in `buffer` at which to begin writing. Default: 0
+
+Example parsing and unparsing a UUID string
+
+```javascript
+var bytes = uuid.parse('797ff043-11eb-11e1-80d6-510998755d10'); // -> <Buffer 79 7f f0 43 11 eb 11 e1 80 d6 51 09 98 75 5d 10>
+var string = uuid.unparse(bytes); // -> '797ff043-11eb-11e1-80d6-510998755d10'
+```
+
+### uuid.noConflict()
+
+(Browsers only) Set `uuid` property back to it's previous value.
+
+Returns the node-uuid object.
+
+Example:
+
+```javascript
+var myUuid = uuid.noConflict();
+myUuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'
+```
+
+## Deprecated APIs
+
+Support for the following v1.2 APIs is available in v1.3, but is deprecated and will be removed in the next major version.
+
+### uuid([format [, buffer [, offset]]])
+
+uuid() has become uuid.v4(), and the `format` argument is now implicit in the `buffer` argument. (i.e. if you specify a buffer, the format is assumed to be binary).
+
+### uuid.BufferClass
+
+The class of container created when generating binary uuid data if no buffer argument is specified.  This is expected to go away, with no replacement API.
+
+## Command Line Interface
+
+To use the executable, it's probably best to install this library globally.
+
+`npm install -g node-uuid`
+
+Usage:
+
+```
+USAGE: uuid [version] [options]
+
+
+options:
+
+--help                     Display this message and exit
+```
+
+`version` must be an RFC4122 version that is supported by this library, which is currently version 1 and version 4 (denoted by "v1" and "v4", respectively). `version` defaults to version 4 when not supplied.
+
+### Examples
+
+```
+> uuid
+3a91f950-dec8-4688-ba14-5b7bbfc7a563
+```
+
+```
+> uuid v1
+9d0b43e0-7696-11e3-964b-250efa37a98e
+```
+
+```
+> uuid v4
+6790ac7c-24ac-4f98-8464-42f6d98a53ae
+```
+
+## Testing
+
+In node.js
+
+```
+npm test
+```
+
+In Browser
+
+```
+open test/test.html
+```
+
+### Benchmarking
+
+Requires node.js
+
+```
+npm install uuid uuid-js
+node benchmark/benchmark.js
+```
+
+For a more complete discussion of node-uuid performance, please see the `benchmark/README.md` file, and the [benchmark wiki](https://github.com/broofa/node-uuid/wiki/Benchmark)
+
+For browser performance [checkout the JSPerf tests](http://jsperf.com/node-uuid-performance).
+
+## Release notes
+
+### 1.4.0
+
+* Improved module context detection
+* Removed public RNG functions
+
+### 1.3.2
+
+* Improve tests and handling of v1() options (Issue #24)
+* Expose RNG option to allow for perf testing with different generators
+
+### 1.3.0
+
+* Support for version 1 ids, thanks to [@ctavan](https://github.com/ctavan)!
