-"""For neatly implementing static typing in pip.
-
-`mypy` - the static type analysis tool we use - uses the `typing` module, which
-provides core functionality fundamental to mypy's functioning.
-
-Generally, `typing` would be imported at runtime and used in that fashion -
-it acts as a no-op at runtime and does not have any run-time overhead by
-design.
-
-As it turns out, `typing` is not vendorable - it uses separate sources for
-Python 2/Python 3. Thus, this codebase can not expect it to be present.
-To work around this, mypy allows the typing import to be behind a False-y
-optional to prevent it from running at runtime and type-comments can be used
-to remove the need for the types to be accessible directly during runtime.
-
-This module provides the False-y guard in a nicely named fashion so that a
-curious maintainer can reach here to read this.
-
-In pip, all static-typing related imports should be guarded as follows:
-
- from pip._internal.utils.typing import MYPY_CHECK_RUNNING
-
- if MYPY_CHECK_RUNNING:
- from typing import ...
-
-Ref: https://github.com/python/mypy/issues/3216

- # Special case pip and setuptools to generate versioned wrappers
- #
- # The issue is that some projects (specifically, pip and setuptools) use
- # code in setup.py to create "versioned" entry points - pip2.7 on Python
- # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
- # the wheel metadata at build time, and so if the wheel is installed with
- # a *different* version of Python the entry points will be wrong. The
- # correct fix for this is to enhance the metadata to be able to describe
- # such versioned entry points, but that won't happen till Metadata 2.0 is
- # available.
- # In the meantime, projects using versioned entry points will either have
- # incorrect versioned entry points, or they will not be able to distribute
- # "universal" wheels (i.e., they will need a wheel per Python version).
- #
- # Because setuptools and pip are bundled with _ensurepip and virtualenv,
- # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
- # override the versioned entry points in the wheel and generate the
- # correct ones. This code is purely a short-term measure until Metadata 2.0
- # is available.
- #
- # To add the level of hack in this section of code, in order to support
- # ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
- # variable which will control which version scripts get installed.
- #
- # ENSUREPIP_OPTIONS=altinstall
- # - Only pipX.Y and easy_install-X.Y will be generated and installed
- # ENSUREPIP_OPTIONS=install

- # that this option is technically if ENSUREPIP_OPTIONS is set and is

-HTML parsing library based on the `WHATWG HTML specification
-<https://whatwg.org/html>`_. The parser is designed to be compatible with

-is largely compatible with modern desktop web browsers.
-
-Example usage::
-
- from pip._vendor import html5lib
- with open("my_document.html", "rb") as f:
- tree = html5lib.parse(f)
-
-For convenience, this module re-exports the following names:

- arguments:
-
- :param file_like:
- File-like object having `.read(n)` method.
- If specified, unpacker reads serialized data from it and :meth:`feed()` is not usable.
-
- :param int read_size:
- Used as `file_like.read(read_size)`. (default: `min(16*1024, max_buffer_size)`)
-
- :param bool use_list:
- If true, unpack msgpack array to Python list.
- Otherwise, unpack to Python tuple. (default: True)
-
- :param bool raw:
- If true, unpack msgpack raw to Python bytes (default).
- Otherwise, unpack to Python str (or unicode on Python 2) by decoding
- with UTF-8 encoding (recommended).
- Currently, the default is true, but it will be changed to false in
- near future. So you must specify it explicitly for keeping backward
- compatibility.
-
- *encoding* option which is deprecated overrides this option.
-
- :param bool strict_map_key:
- If true, only str or bytes are accepted for map (dict) keys.
- It's False by default for backward-compatibility.
- But it will be True from msgpack 1.0.
-
- :param callable object_hook:
- When specified, it should be callable.
- Unpacker calls it with a dict argument after unpacking msgpack map.
- (See also simplejson)
-
- :param callable object_pairs_hook:
- When specified, it should be callable.
- Unpacker calls it with a list of key-value pairs after unpacking msgpack map.
- (See also simplejson)
-
- :param str encoding:
- Encoding used for decoding msgpack raw.
- If it is None (default), msgpack raw is deserialized to Python bytes.
-
- :param str unicode_errors:
- (deprecated) Used for decoding msgpack raw with *encoding*.
- (default: `'strict'`)
-
- :param int max_buffer_size:
- Limits size of data waiting unpacked. 0 means system's INT_MAX (default).
- Raises `BufferFull` exception when it is insufficient.
- You should set this parameter when unpacking data from untrusted source.
-
- :param int max_str_len:
- Deprecated, use *max_buffer_size* instead.
- Limits max length of str. (default: max_buffer_size or 1024*1024)
-
- :param int max_bin_len:
- Deprecated, use *max_buffer_size* instead.
- Limits max length of bin. (default: max_buffer_size or 1024*1024)
-
- :param int max_array_len:
- Limits max length of array.
- (default: max_buffer_size or 128*1024)
-
- :param int max_map_len:
- Limits max length of map.
- (default: max_buffer_size//2 or 32*1024)
-
- :param int max_ext_len:
- Deprecated, use *max_buffer_size* instead.
- Limits max size of ext type. (default: max_buffer_size or 1024*1024)

- usage:
-
- packer = Packer()
- astream.write(packer.pack(a))
- astream.write(packer.pack(b))
-
- Packer's constructor has some keyword arguments:
-
- :param callable default:
- Convert user type to builtin type that Packer supports.
- See also simplejson's document.
-
- :param bool use_single_float:
- Use single precision float type for float. (default: False)
-
- :param bool autoreset:
- Reset buffer after each pack and return its content as `bytes`. (default: True).
- If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
-
- :param bool use_bin_type:
- Use bin type introduced in msgpack spec 2.0 for bytes.
- It also enables str8 type for unicode.
-
- :param bool strict_types:
- If set to true, types will be checked to be exact. Derived classes
- from serializeable types will not be serialized and will be
- treated as unsupported type and forwarded to default.
- Additionally tuples will not be serialized as lists.
- This is useful when trying to implement accurate serialization
- for python types.

-Package resource API
---------------------
-
-A resource is a logical file contained within a package, or a logical
-subdirectory thereof. The package resource API expects resource names
-to have their path parts separated with ``/``, *not* whatever the local
-path separator is. Do not use os.path operations to manipulate resource
-names being passed into the API.
-
-The package resource API is designed to work with normal filesystem packages,
-.egg files, and unpacked .egg files. It can also work in a limited way with
-.zip files and with custom PEP 302 loaders that support the ``get_data()``
-method.

-pyparsing module - Classes and methods to define and execute parsing grammars
-=============================================================================
-
-The pyparsing module is an alternative approach to creating and
-executing simple grammars, vs. the traditional lex/yacc approach, or the
-use of regular expressions. With pyparsing, you don't need to learn
-a new syntax for defining grammars or matching expressions - the parsing
-module provides a library of classes that you use to construct the
-grammar directly in Python.
-
-Here is a program to parse "Hello, World!" (or any greeting of the form
-``"<salutation>, <addressee>!"``), built up using :class:`Word`,
-:class:`Literal`, and :class:`And` elements
-(the :class:`'+'<ParserElement.__add__>` operators create :class:`And` expressions,
-and the strings are auto-converted to :class:`Literal` expressions)::
-
- from pip._vendor.pyparsing import Word, alphas
-
- # define grammar of a greeting
- greet = Word(alphas) + "," + Word(alphas) + "!"
-
- hello = "Hello, World!"
- print (hello, "->", greet.parseString(hello))
-
-The program outputs the following::
-
- Hello, World! -> ['Hello', ',', 'World', '!']
-
-The Python representation of the grammar is quite readable, owing to the
-self-explanatory class names, and the use of '+', '|' and '^' operators.
-
-The :class:`ParseResults` object returned from
-:class:`ParserElement.parseString` can be
-accessed as a nested list, a dictionary, or an object with named
-attributes.
-
-The pyparsing module handles some of the problems that are typically
-vexing when writing text parsers:
-
- - extra or missing whitespace (the above program will also handle
- "Hello,World!", "Hello , World !", etc.)
- - quoted strings
- - embedded comments
-
-
-Getting Started -
------------------
-Visit the classes :class:`ParserElement` and :class:`ParseResults` to
-see the base classes that most other pyparsing
-classes inherit from. Use the docstrings for examples of how to:
-
- - construct literal match expressions from :class:`Literal` and
- :class:`CaselessLiteral` classes
- - construct character word-group expressions using the :class:`Word`
- class
- - see how to create repetitive expressions using :class:`ZeroOrMore`
- and :class:`OneOrMore` classes
- - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`,
- and :class:`'&'<Each>` operators to combine simple expressions into
- more complex ones
- - associate names with your parsed results using
- :class:`ParserElement.setResultsName`
- - find some helpful expression short-cuts like :class:`delimitedList`
- and :class:`oneOf`
- - find more useful common expressions in the :class:`pyparsing_common`
- namespace class

-class Word(Token):
- """Token for matching words composed of allowed character sets.
- Defined with string containing all allowed initial characters, an
- optional string containing allowed body characters (if omitted,
- defaults to the initial character set), and an optional minimum,
- maximum, and/or exact length. The default value for ``min`` is
- 1 (a minimum value < 1 is not valid); the default values for
- ``max`` and ``exact`` are 0, meaning no maximum or exact
- length restriction. An optional ``excludeChars`` parameter can
- list characters that might be found in the input ``bodyChars``
- string; useful to define a word of all printables except for one or
- two characters, for instance.
-
- :class:`srange` is useful for defining custom character set strings
- for defining ``Word`` expressions, using range notation from
- regular expression character sets.
-
- A common mistake is to use :class:`Word` to match a specific literal
- string, as in ``Word("Address")``. Remember that :class:`Word`
- uses the string argument to define *sets* of matchable characters.
- This expression would match "Add", "AAA", "dAred", or any other word
- made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an
- exact literal string, use :class:`Literal` or :class:`Keyword`.
-
- pyparsing includes helper strings for building Words:
-
- - :class:`alphas`
- - :class:`nums`
- - :class:`alphanums`
- - :class:`hexnums`
- - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255
- - accented, tilded, umlauted, etc.)
- - :class:`punc8bit` (non-alphabetic characters in ASCII range
- 128-255 - currency, symbols, superscripts, diacriticals, etc.)
- - :class:`printables` (any non-whitespace character)
-
- Example::
-
- # a word composed of digits
- integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
-
- # a word with a leading capital, and zero or more lowercase
- capital_word = Word(alphas.upper(), alphas.lower())
-
- # hostnames are alphanumeric, with leading alpha, and '-'
- hostname = Word(alphas, alphanums+'-')
-
- # roman numeral (not a strict parser, accepts invalid mix of characters)
- roman = Word("IVXLCDM")
-
- # any string of non-whitespace characters, except for ','
- csv_value = Word(printables, excludeChars=",")

-Requests HTTP Library
-~~~~~~~~~~~~~~~~~~~~~
-
-Requests is an HTTP library, written in Python, for human beings. Basic GET
-usage:
-
- >>> import requests
- >>> r = requests.get('https://www.python.org')
- >>> r.status_code
- 200
- >>> 'Python is a programming language' in r.content
- True
-
-... or POST:
-
- >>> payload = dict(key1='value1', key2='value2')
- >>> r = requests.post('https://httpbin.org/post', data=payload)
- >>> print(r.text)
- {
- ...
- "form": {
- "key2": "value2",
- "key1": "value1"
- },
- ...
- }
-
-The other HTTP methods are supported - see `requests.api`. Full documentation
-is at <http://python-requests.org>.

- will disable redirect, too.

- back into the pool once a response is received (but will release if
- you read the entire contents of the response such as when

- the response's content immediately. You will need to call

-This module contains provisional support for SOCKS proxies from within
-urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
-SOCKS5. To enable its functionality, either install PySocks or install this
-module with the ``socks`` extra.
-
-The SOCKS implementation supports the full range of urllib3 features. It also
-supports the following SOCKS features:
-
-- SOCKS4A (``proxy_url='socks4a://...``)
-- SOCKS4 (``proxy_url='socks4://...``)
-- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
-- SOCKS5 with local DNS (``proxy_url='socks5://...``)
-- Usernames and passwords for the SOCKS proxy
-
- .. note::
- It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
- your ``proxy_url`` to ensure that DNS resolution is done from the remote
- server instead of client-side when connecting to a domain name.
-
-SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
-supports IPv4, IPv6, and domain names.
-
-When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
-will be sent as the ``userid`` section of the SOCKS request::
-
- proxy_url="socks4a://<userid>@proxy-host"
-
-When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
-of the ``proxy_url`` will be sent as the username/password to authenticate
-with the proxy::
-
- proxy_url="socks5h://<username>:<password>@proxy-host"

-
- When uploading a file, providing a filename (the first parameter of the

- will be set to the time leftover from the connect attempt. In the

- timeout and a total are specified, the shorter timeout will be applied.
-
- Defaults to None.
-
- :type total: integer, float, or None
-
- :param connect:
- The maximum amount of time to wait for a connection attempt to a server
- to succeed. Omitting the parameter will default the connect timeout to
- the system default, probably `the global default timeout in socket.py
- <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
- None will set an infinite timeout for connection attempts.
-
- :type connect: integer, float, or None

- :param read:
- The maximum amount of time to wait between consecutive

- default, probably `the global default timeout in socket.py

- .. note::
-
- Many factors can affect the total amount of time for urllib3 to return
- an HTTP response.
-
- For example, Python's DNS resolver does not obey the timeout specified
- on the socket. Other factors that can affect total request time include
- high CPU load, high swap, the program running at a low priority level,
- or other behaviors.
-
- In addition, the read and total timeouts only measure the time between
- read operations on the socket connecting the client and the server,
- not the total amount of time for the request to return a complete
- response. For most requests, the timeout is raised because the server
- has not sent the first byte in the specified time. This is not always
- the case; if a server streams one byte every fifteen seconds, a timeout
- of 20 seconds will not trigger, even though the request will take
- several minutes to complete.
-
- If your goal is to cut off any request after a set amount of wall clock
- time, consider having a second "watcher" thread to cut off a slow
- request.

-Package resource API
---------------------
-
-A resource is a logical file contained within a package, or a logical
-subdirectory thereof. The package resource API expects resource names
-to have their path parts separated with ``/``, *not* whatever the local
-path separator is. Do not use os.path operations to manipulate resource
-names being passed into the API.
-
-The package resource API is designed to work with normal filesystem packages,
-.egg files, and unpacked .egg files. It can also work in a limited way with
-.zip files and with custom PEP 302 loaders that support the ``get_data()``
-method.

-pyparsing module - Classes and methods to define and execute parsing grammars
-=============================================================================
-
-The pyparsing module is an alternative approach to creating and executing simple grammars,
-vs. the traditional lex/yacc approach, or the use of regular expressions. With pyparsing, you
-don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
-provides a library of classes that you use to construct the grammar directly in Python.
-
-Here is a program to parse "Hello, World!" (or any greeting of the form
-C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements
-(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
-L{Literal} expressions)::
-
- from pyparsing import Word, alphas
-
- # define grammar of a greeting
- greet = Word(alphas) + "," + Word(alphas) + "!"
-
- hello = "Hello, World!"
- print (hello, "->", greet.parseString(hello))
-
-The program outputs the following::
-
- Hello, World! -> ['Hello', ',', 'World', '!']
-
-The Python representation of the grammar is quite readable, owing to the self-explanatory
-class names, and the use of '+', '|' and '^' operators.
-
-The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
-object with named attributes.
-
-The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
- - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.)
- - quoted strings
- - embedded comments
-
-
-Getting Started -
------------------
-Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
-classes inherit from. Use the docstrings for examples of how to:
- - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
- - construct character word-group expressions using the L{Word} class
- - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
- - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
- - associate names with your parsed results using L{ParserElement.setResultsName}
- - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
- - find more useful common expressions in the L{pyparsing_common} namespace class

- Token for matching words composed of allowed character sets.
- Defined with string containing all allowed initial characters,
- an optional string containing allowed body characters (if omitted,
- defaults to the initial character set), and an optional minimum,
- maximum, and/or exact length. The default value for C{min} is 1 (a
- minimum value < 1 is not valid); the default values for C{max} and C{exact}
- are 0, meaning no maximum or exact length restriction. An optional
- C{excludeChars} parameter can list characters that might be found in
- the input C{bodyChars} string; useful to define a word of all printables
- except for one or two characters, for instance.
-
- L{srange} is useful for defining custom character set strings for defining
- C{Word} expressions, using range notation from regular expression character sets.
-
- A common mistake is to use C{Word} to match a specific literal string, as in
- C{Word("Address")}. Remember that C{Word} uses the string argument to define
- I{sets} of matchable characters. This expression would match "Add", "AAA",
- "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
- To match an exact literal string, use L{Literal} or L{Keyword}.
-
- pyparsing includes helper strings for building Words:
- - L{alphas}
- - L{nums}
- - L{alphanums}
- - L{hexnums}
- - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
- - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
- - L{printables} (any non-whitespace character)
-
- Example::
- # a word composed of digits
- integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
-
- # a word with a leading capital, and zero or more lowercase
- capital_word = Word(alphas.upper(), alphas.lower())

-PyObjC is a bridge between Python and Objective-C. It allows full
-featured Cocoa applications to be written in pure Python. It is also
-easy to use other frameworks containing Objective-C class libraries
-from Python and to mix in Objective-C, C and C++ source.
-
-This package is a pseudo-package that will install all pyobjc related
-packages (that is, pyobjc-core as well as wrappers for frameworks on
-macOS)

-
-PyObjC is a bridge between Python and Objective-C. It allows full
-featured Cocoa applications to be written in pure Python. It is also
-easy to use other frameworks containing Objective-C class libraries
-from Python and to mix in Objective-C, C and C++ source.
-
-Python is a highly dynamic programming language with a shallow learning
-curve. It combines remarkable power with very clear syntax.
-
-PyObjC also supports full introspection of Objective-C classes and
-direct invocation of Objective-C APIs from the interactive interpreter.

-PyObjC wrappers for the framework "CFNetwork", part of "CoreServices" on
-macOS.
-
-The CFNetwork framework provides a library of abstractions for networking
-protocols. The most interesting bits for Python programmers are the
-API's for working with proxy autoconfiguration and the API's for networking
-diagnotics.
-
-These wrappers don't include documentation, please check Apple's documention
-for information on how to use this framework and PyObjC's documentation
-for general tips and tricks regarding the translation between Python
-and (Objective-)C frameworks

-Wrappers for the "Quartz" related frameworks on macOS. These frameworks
-provide a number of graphics related API's.
-
-The frameworks wrapped by this package are:
-
- * CoreGraphics - 2D Graphics, based on the PDF model
-
- * ImageIO - Reading and writing images
-
- * QuartzComposer - Working with "Quartz Composer" compositions
-
- * QuartzCore - Image processing and video image manipulation
-
- * QuarzFilters - Image effects
-
- * ImageKit - iPhoto-like views
-
- * PDFKit - Working with PDF files
-
- * CoreVideo - Managing digital video
-
-All frameworks can be accessed by importing the 'Quartz' module.
-
-These wrappers don't include documentation, please check Apple's documention
-for information on how to use this framework and PyObjC's documentation
-for general tips and tricks regarding the translation between Python
-and (Objective-)C frameworks
-
-NOTE: The actual wrappers are subpackages of ``Quartz``, they are not toplevel
-packages to avoid name clashes with Apple provided wrappers for CoreGraphics.
-
-WARNING: Running the unittests will change your display settings during the
-testrun, which will probably mess up your window layout.

-Wrappers for the "ScriptingBrige" framework on macOS 10.5 or later. This
-framework provides an easy way to use the scripting functionality of
-applications ("AppleScript") from Cocoa applications.
-
-The functionality of this framework is comparable to that off "appscript",
-although the latter is better tuned for use in Python applications and is
-available on macOS 10.4 as well.
-
-These wrappers don't include documentation, please check Apple's documention

-Wrappers for the "SyncServices" framework on macOS.
-
-Sync Services is a framework containing all the components you need
-to sync your applications and devices. If your application uses
-Sync Services, user data can be synced with other applications and
-devices on the same computer, or other computers over the network via
-MobileMe.
-
-These wrappers don't include documentation, please check Apple's documention
-for information on how to use this framework and PyObjC's documentation
-for general tips and tricks regarding the translation between Python
-and (Objective-)C frameworks

-pyparsing module - Classes and methods to define and execute parsing grammars
-=============================================================================
-
-The pyparsing module is an alternative approach to creating and executing simple grammars,
-vs. the traditional lex/yacc approach, or the use of regular expressions. With pyparsing, you
-don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
-provides a library of classes that you use to construct the grammar directly in Python.
-
-Here is a program to parse "Hello, World!" (or any greeting of the form
-C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements
-(L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to
-L{Literal} expressions)::
-
- from pyparsing import Word, alphas
-
- # define grammar of a greeting
- greet = Word(alphas) + "," + Word(alphas) + "!"
-
- hello = "Hello, World!"
- print (hello, "->", greet.parseString(hello))
-
-The program outputs the following::
-
- Hello, World! -> ['Hello', ',', 'World', '!']
-
-The Python representation of the grammar is quite readable, owing to the self-explanatory
-class names, and the use of '+', '|' and '^' operators.
-
-The L{ParseResults} object returned from L{ParserElement.parseString<ParserElement.parseString>} can be accessed as a nested list, a dictionary, or an
-object with named attributes.
-
-The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
- - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello , World !", etc.)
- - quoted strings
- - embedded comments
-
-
-Getting Started -
------------------
-Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
-classes inherit from. Use the docstrings for examples of how to:
- - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
- - construct character word-group expressions using the L{Word} class
- - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
- - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
- - associate names with your parsed results using L{ParserElement.setResultsName}
- - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
- - find more useful common expressions in the L{pyparsing_common} namespace class

- Repeated parse attempts at the same string location (which happens

- both valid results and parsing exceptions.
-

- - cache_size_limit - (default=C{128}) - if an integer value is provided
- will limit the size of the packrat cache; if None is passed, then
- the cache size will be unbounded; if 0 is passed, the cache will
- be effectively disabled.
-
- This speedup may break existing programs that use parse actions that
- have side-effects. For this reason, packrat parsing is disabled when
- you first import pyparsing. To activate the packrat feature, your
- program must call the class method C{ParserElement.enablePackrat()}. If
- your program uses C{psyco} to "compile as you go", you must call
- C{enablePackrat} before calling C{psyco.full()}. If you do not do this,
- Python will crash. For best results, call C{enablePackrat()} immediately

- Token for matching words composed of allowed character sets.
- Defined with string containing all allowed initial characters,
- an optional string containing allowed body characters (if omitted,
- defaults to the initial character set), and an optional minimum,
- maximum, and/or exact length. The default value for C{min} is 1 (a
- minimum value < 1 is not valid); the default values for C{max} and C{exact}
- are 0, meaning no maximum or exact length restriction. An optional
- C{excludeChars} parameter can list characters that might be found in
- the input C{bodyChars} string; useful to define a word of all printables
- except for one or two characters, for instance.
-
- L{srange} is useful for defining custom character set strings for defining
- C{Word} expressions, using range notation from regular expression character sets.
-
- A common mistake is to use C{Word} to match a specific literal string, as in
- C{Word("Address")}. Remember that C{Word} uses the string argument to define
- I{sets} of matchable characters. This expression would match "Add", "AAA",
- "dAred", or any other word made up of the characters 'A', 'd', 'r', 'e', and 's'.
- To match an exact literal string, use L{Literal} or L{Keyword}.
-
- pyparsing includes helper strings for building Words:
- - L{alphas}
- - L{nums}
- - L{alphanums}
- - L{hexnums}
- - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.)
- - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.)
- - L{printables} (any non-whitespace character)
-
- Example::
- # a word composed of digits
- integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
-
- # a word with a leading capital, and zero or more lowercase

- Helper method for constructing grammars of expressions made up of
- operators working in a precedence hierarchy. Operators may be unary or
- binary, left- or right-associative. Parse actions can also be attached
- to operator expressions. The generated parser will also recognize the use
- of parentheses to override operator precedences (see example below).
-
- Note: if you define a deep operator list, you may see performance issues
- when using infixNotation. See L{ParserElement.enablePackrat} for a
- mechanism to potentially improve your parser performance.
-
- Parameters:
- - baseExpr - expression representing the most basic element for the nested
- - opList - list of tuples, one for each operator precedence level in the
- expression grammar; each tuple is of the form
- (opExpr, numTerms, rightLeftAssoc, parseAction), where:
- - opExpr is the pyparsing expression for the operator;
- may also be a string, which will be converted to a Literal;
- if numTerms is 3, opExpr is a tuple of two expressions, for the
- two operators separating the 3 terms
- - numTerms is the number of terms for this operator (must
- be 1, 2, or 3)
- - rightLeftAssoc is the indicator whether the operator is
- right or left associative, using the pyparsing-defined
- constants C{opAssoc.RIGHT} and C{opAssoc.LEFT}.
- - parseAction is the parse action to be associated with
- expressions matching this operator expression (the
- parse action tuple member may be omitted); if the parse action
- is passed a tuple or list of functions, this is equivalent to
- calling C{setParseAction(*fn)} (L{ParserElement.setParseAction})
- - lpar - expression for matching left-parentheses (default=C{Suppress('(')})

- is used to load data from a new zipped egg archive, it may cause the
- operation to attempt to locate the requested data in the wrong location -

- our best to clear any remaining zipimport.zipimporter related cached data
- that might somehow later get used when attempting to load data from the new
- distribution and thus cause such load operations to fail. Note that when
- tracking down such remaining stale data, we can not catch every conceivable
- usage from here, and we clear only those that we know of and have found to

-
-class Distribution(_Distribution):
- """Distribution with support for features, tests, and package data
-
- This is an enhanced version of 'distutils.dist.Distribution' that
- effectively adds the following new optional keyword arguments to 'setup()':
-
- 'install_requires' -- a string or sequence of strings specifying project
- versions that the distribution requires when installed, in the format
- used by 'pkg_resources.require()'. They will be installed
- automatically when the package is installed. If you wish to use
- packages that are not available in PyPI, or want to give your users an
- alternate download location, you can add a 'find_links' option to the
- '[easy_install]' section of your project's 'setup.cfg' file, and then
- setuptools will scan the listed web pages for links that satisfy the
- requirements.
-
- 'extras_require' -- a dictionary mapping names of optional "extras" to the
- additional requirement(s) that using those extras incurs. For example,
- this::
-
- extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
-
- indicates that the distribution can optionally provide an extra
- capability called "reST", but it can only be used if docutils and
- reSTedit are installed. If the user installs your package using
- EasyInstall and requests one of your extras, the corresponding
- additional requirements will be installed if needed.
-
- 'features' **deprecated** -- a dictionary mapping option names to
- 'setuptools.Feature'
- objects. Features are a portion of the distribution that can be
- included or excluded based on user options, inter-feature dependencies,
- and availability on the current system. Excluded features are omitted
- from all setup commands, including source and binary distributions, so
- you can create multiple distributions from the same source tree.
- Feature names should be valid Python identifiers, except that they may
- contain the '-' (minus) sign. Features can be included or excluded
- via the command line options '--with-X' and '--without-X', where 'X' is
- the name of the feature. Whether a feature is included by default, and
- whether you are allowed to control this from the command line, is
- determined by the Feature object. See the 'Feature' class for more
- information.
-
- 'test_suite' -- the name of a test suite to run for the 'test' command.
- If the user runs 'python setup.py test', the package will be installed,
- and the named test suite will be run. The format is the same as
- would be used on a 'unittest.py' command line. That is, it is the
- dotted name of an object to import and call to generate a test suite.
-
- 'package_data' -- a dictionary mapping package names to lists of filenames
- or globs to use to find data files contained in the named packages.
- If the dictionary has filenames or globs listed under '""' (the empty
- string), those names will be searched for in every package, in addition
- to any names for the specific package. Data files found using these
- names/globs will be installed along with the package, in the same
- location as the package. Note that globs are allowed to reference
- the contents of non-package subdirectories, as long as you use '/' as
- a path separator. (Globs are automatically converted to
- platform-specific paths at runtime.)
-
- In addition to these new keywords, this class also has several new methods
- for manipulating the distribution's contents. For example, the 'include()'
- and 'exclude()' methods can be thought of as in-place add and subtract
- commands that add or remove packages, modules, extensions, and so on from
- the distribution. They are used by the feature subsystem to configure the
- distribution for the included and excluded features.

- **deprecated** -- The `Feature` facility was never completely implemented

- <https://github.com/pypa/setuptools/issues/58>`_ and will be removed in
- a future version.
-
- A subset of the distribution that can be excluded if unneeded/wanted
-
- Features are created using these keyword arguments:
-
- 'description' -- a short, human readable description of the feature, to
- be used in error messages, and option help messages.
-
- 'standard' -- if true, the feature is included by default if it is
- available on the current system. Otherwise, the feature is only
- included if requested via a command line '--with-X' option, or if
- another included feature requires it. The default setting is 'False'.
-
- 'available' -- if true, the feature is available for installation on the
- current system. The default setting is 'True'.
-
- 'optional' -- if true, the feature's inclusion can be controlled from the
- command line, using the '--with-X' or '--without-X' options. If
- false, the feature's inclusion status is determined automatically,
- based on 'availabile', 'standard', and whether any other feature
- requires it. The default setting is 'True'.
-
- 'require_features' -- a string or sequence of strings naming features
- that should also be included if this feature is included. Defaults to
- empty list. May also contain 'Require' objects that should be
- added/removed from the distribution.
-
- 'remove' -- a string or list of strings naming packages to be removed
- from the distribution if this feature is *not* included. If the
- feature *is* included, this argument is ignored. This argument exists
- to support removing features that "crosscut" a distribution, such as
- defining a 'tests' feature that removes all the 'tests' subpackages
- provided by other features. The default for this argument is an empty
- list. (Note: the named package(s) or modules must exist in the base
- distribution when the 'setup()' function is initially called.)
-
- other keywords -- any other keyword arguments are saved, and passed to
- the distribution's 'include()' and 'exclude()' methods when the
- feature is included or excluded, respectively. So, for example, you
- could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be
- added or removed from the distribution as appropriate.
-
- A feature must include at least one 'requires', 'remove', or other
- keyword argument. Otherwise, it can't affect the distribution in any way.
- Note also that you can subclass 'Feature' to create your own specialized
- feature types that modify the distribution in other ways when included or
- excluded. See the docstrings for the various methods here for more detail.
- Aside from the methods, the only feature attributes that distributions look
- at are 'description' and 'optional'.

-wheel
-=====
-
-This library is the reference implementation of the Python wheel packaging
-standard, as defined in `PEP 427`_.
-
-It has two different roles:
-
-#. A setuptools_ extension for building wheels that provides the
- ``bdist_wheel`` setuptools command
-#. A command line tool for working with wheel files
-
-It should be noted that wheel is **not** intended to be used as a library, and
-as such there is no stable, public API.
-
-.. _PEP 427: https://www.python.org/dev/peps/pep-0427/
-.. _setuptools: https://pypi.org/project/setuptools/
-
-
-Code of Conduct
----------------
-
-Everyone interacting in the wheel project's codebases, issue trackers, chat
-rooms, and mailing lists is expected to follow the `PyPA Code of Conduct`_.

- 4. The architecture must be taken from the installer filename, as it is

-"""Append module search paths for third-party packages to sys.path.
-
-****************************************************************
-* This module is automatically imported during initialization. *
-****************************************************************
-
-In earlier versions of Python (up to 1.5a3), scripts or modules that
-needed to use site-specific modules would place ``import site''
-somewhere near the top of their code. Because of the automatic
-import, this is no longer necessary (but code that does it still
-works).
-
-This will append site-specific paths to the module search path. On
-Unix, it starts with sys.prefix and sys.exec_prefix (if different) and
-appends lib/python<version>/site-packages as well as lib/site-python.
-It also supports the Debian convention of
-lib/python<version>/dist-packages. On other platforms (mainly Mac and
-Windows), it uses just sys.prefix (and sys.exec_prefix, if different,
-but this is unlikely). The resulting directories, if they exist, are
-appended to sys.path, and also inspected for path configuration files.
-
-FOR DEBIAN, this sys.path is augmented with directories in /usr/local.
-Local addons go into /usr/local/lib/python<version>/site-packages
-(resp. /usr/local/lib/site-python), Debian addons install into
-/usr/{lib,share}/python<version>/dist-packages.
-
-A path configuration file is a file whose name has the form
-<package>.pth; its contents are additional directories (one per line)
-to be added to sys.path. Non-existing directories (or
-non-directories) are never added to sys.path; no directory is added to
-sys.path more than once. Blank lines and lines beginning with
-'#' are skipped. Lines starting with 'import' are executed.
-
-For example, suppose sys.prefix and sys.exec_prefix are set to
-/usr/local and there is a directory /usr/local/lib/python2.X/site-packages
-with three subdirectories, foo, bar and spam, and two path
-configuration files, foo.pth and bar.pth. Assume foo.pth contains the
-following:
-
- # foo package configuration
- foo
- bar
- bletch
-
-and bar.pth contains:
-
- # bar package configuration
- bar
-
-Then the following directories are added to sys.path, in this order:
-
- /usr/local/lib/python2.X/site-packages/bar
- /usr/local/lib/python2.X/site-packages/foo
-
-Note that bletch is omitted because it doesn't exist; bar precedes foo
-because bar.pth comes alphabetically before foo.pth; and spam is
-omitted because it is not mentioned in either path configuration file.
-
-After these path manipulations, an attempt is made to import a module
-named sitecustomize, which can perform arbitrary additional
-site-specific customizations. If this import fails with an
-ImportError exception, it is silently ignored.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public

+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+adodbapi
+
+A Python DB-API 2.0 (PEP-249) module that makes it easy to use Microsoft ADO
+for connecting with databases and other data sources
+using either CPython or IronPython.
+
+Home page: <http://sourceforge.net/projects/adodbapi>
+
+Features:
+* 100% DB-API 2.0 (PEP-249) compliant (including most extensions and recommendations).
+* Includes pyunit testcases that describe how to use the module.
+* Fully implemented in Python. -- runs in Python 2.5+ Python 3.0+ and IronPython 2.6+
+* Licensed under the LGPL license, which means that it can be used freely even in commercial programs subject to certain restrictions.
+* The user can choose between paramstyles: 'qmark' 'named' 'format' 'pyformat' 'dynamic'
+* Supports data retrieval by column name e.g.:
+ for row in myCurser.execute("select name,age from students"):
+ print("Student", row.name, "is", row.age, "years old.")
+* Supports user-definable system-to-Python data conversion functions (selected by ADO data type, or by column)
+
+Prerequisites:
+* C Python 2.7 or 3.5 or higher
+ and pywin32 (Mark Hammond's python for windows extensions.)
+or
+ Iron Python 2.7 or higher. (works in IPy2.0 for all data types except BUFFER)
+
+Installation:
+* (C-Python on Windows): Install pywin32 ("pip install pywin32") which includes adodbapi.
+* (IronPython on Windows): Download adodbapi from http://sf.net/projects/adodbapi. Unpack the zip.
+ Open a command window as an administrator. CD to the folder containing the unzipped files.
+ Run "setup.py install" using the IronPython of your choice.
+
+NOTE: ...........
+If you do not like the new default operation of returning Numeric columns as decimal.Decimal,
+you can select other options by the user defined conversion feature.
+Try:
+ adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = adodbapi.apibase.cvtString
+or:
+ adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = adodbapi.apibase.cvtFloat
+or:
+ adodbapi.apibase.variantConversions[adodbapi.ado_consts.adNumeric] = write_your_own_convertion_function
+ ............
+notes for 2.6.2:
+ The definitive source has been moved to https://github.com/mhammond/pywin32/tree/master/adodbapi.
+ Remote has proven too hard to configure and test with Pyro4. I am moving it to unsupported status
+ until I can change to a different connection method.
+whats new in version 2.6
+ A cursor.prepare() method and support for prepared SQL statements.
+ Lots of refactoring, especially of the Remote and Server modules (still to be treated as Beta code).
+ The quick start document 'quick_reference.odt' will export as a nice-looking pdf.
+ Added paramstyles 'pyformat' and 'dynamic'. If your 'paramstyle' is 'named' you _must_ pass a dictionary of
+ parameters to your .execute() method. If your 'paramstyle' is 'format' 'pyformat' or 'dynamic', you _may_
+ pass a dictionary of parameters -- provided your SQL operation string is formatted correctly.
+
+whats new in version 2.5
+ Remote module: (works on Linux!) allows a Windows computer to serve ADO databases via PyRO
+ Server module: PyRO server for ADO. Run using a command like= C:>python -m adodbapi.server
+ (server has simple connection string macros: is64bit, getuser, sql_provider, auto_security)
+ Brief documentation included. See adodbapi/examples folder adodbapi.rtf
+ New connection method conn.get_table_names() --> list of names of tables in database
+
+ Vastly refactored. Data conversion things have been moved to the new adodbapi.apibase module.
+ Many former module-level attributes are now class attributes. (Should be more thread-safe)
+ Connection objects are now context managers for transactions and will commit or rollback.
+ Cursor objects are context managers and will automatically close themselves.
+ Autocommit can be switched on and off.
+ Keyword and positional arguments on the connect() method work as documented in PEP 249.
+ Keyword arguments from the connect call can be formatted into the connection string.
+ New keyword arguments defined, such as: autocommit, paramstyle, remote_proxy, remote_port.
+ *** Breaking change: variantConversion lookups are simplified: the following will raise KeyError:
+ oldconverter=adodbapi.variantConversions[adodbapi.adoStringTypes]
+ Refactor as: oldconverter=adodbapi.variantConversions[adodbapi.adoStringTypes[0]]

+read the examples in adodbapi/examples
+and look at the test cases in adodbapi/test directory.
+
+Mailing lists
+-------------
+The adodbapi mailing lists have been deactivated. Submit comments to the
+pywin32 or IronPython mailing lists.

+# - Class renamed
+# - Now a subclass of TestCase, to avoid requiring the driver stub
+# to use multiple inheritance
+# - Reversed the polarity of buggy test in test_description
+# - Test exception heirarchy correctly
+# - self.populate is now self._populate(), so if a driver stub
+# overrides self.ddl1 this change propogates
+# - VARCHAR columns now have a width, which will hopefully make the
+# DDL even more portible (this will be reversed if it causes more problems)
+# - cursor.rowcount being checked after various execute and fetchXXX methods
+# - Check for fetchall and fetchmany returning empty lists after results
+# are exhausted (already checking for empty lists if select retrieved
+# nothing
+# - Fix bugs in test_setoutputsize_basic and test_setinputsizes

+========
+
+**comtypes** is a lightweight Python COM package, based on the ctypes_
+FFI library, in less than 10000 lines of code (not counting the
+tests).
+
+**comtypes** allows to define, call, and implement custom and
+dispatch-based COM interfaces in pure Python. It works on Windows and
+64-bit Windows. Windows CE support was dropped since comtypes==1.1.8.

+"""comtypes.server.register - register and unregister a COM object.
+
+Exports the UseCommandLine function. UseCommandLine is called with
+the COM object classes that a module exposes. It parses the Windows
+command line and takes the appropriate actions.
+These command line options are supported:
+
+/regserver - register the classes with COM.
+/unregserver - unregister the classes with COM.
+
+/nodebug - remove all logging configuration from the registry.
+
+/l <name>=<level> - configure the logging level for the standard Python loggind module,
+this option may be used several times.
+
+/f <formatter> - specify the formatter string.
+
+Note: Registering and unregistering the objects does remove logging
+entries. Configuring the logging does not change other registry
+entries, so it is possible to freeze a comobject with py2exe, register
+it, then configure logging afterwards to debug it, and delete the
+logging config afterwards.
+
+Sample usage:
+
+Register the COM object:
+
+ python mycomobj.py /regserver
+
+Configure logging info:
+
+ python mycomobj.py /l comtypes=INFO /l comtypes.server=DEBUG /f %(message)s
+
+Now, debug the object, and when done delete logging info:
+
+ python mycomobj.py /nodebug

+ based in part on the algorithm of Ouding (1940), as
+ quoted in "Explanatory Supplement to the Astronomical
+ Almanac", P. Kenneth Seidelmann, editor.
+
+ This algorithm implements three different easter
+ calculation methods:
+
+ 1 - Original calculation in Julian calendar, valid in
+ dates after 326 AD
+ 2 - Original method, with date converted to Gregorian
+ calendar, valid in years 1583 to 4099
+ 3 - Revised method, in Gregorian calendar, valid in
+ years 1583 to 4099 as well
+
+ These methods are represented by the constants:
+
+ * ``EASTER_JULIAN = 1``
+ * ``EASTER_ORTHODOX = 2``
+ * ``EASTER_WESTERN = 3``
+
+ The default method is method 3.
+
+ More about the algorithm may be found at:
+
+ `GM Arts: Easter Algorithms <http://www.gmarts.org/index.php?go=415>`_
+
+ and

+"""
+This module offers a generic date/time string parser which is able to parse
+most known formats to represent a date and/or time.
+
+This module attempts to be forgiving with regards to unlikely input formats,
+returning a datetime object even for dates which are ambiguous. If an element
+of a date/time stamp is omitted, the following rules are applied:
+
+- If AM or PM is left unspecified, a 24-hour clock is assumed, however, an hour
+ on a 12-hour clock (``0 <= hour <= 12``) *must* be specified if AM or PM is
+ specified.
+- If a time zone is omitted, a timezone-naive datetime is returned.
+
+If any other elements are missing, they are taken from the
+:class:`datetime.datetime` object passed to the parameter ``default``. If this
+results in a day number exceeding the valid number of days per month, the
+value falls back to the end of the month.
+
+Additional resources about date/time string formats can be found below:

+ Parse an ISO-8601 datetime string into a :class:`datetime.datetime`.
+
+ An ISO-8601 datetime string consists of a date portion, followed
+ optionally by a time portion - the date and time portions are separated
+ by a single character separator, which is ``T`` in the official
+ standard. Incomplete date formats (such as ``YYYY-MM``) may *not* be
+ combined with a time portion.
+
+ Supported date formats are:
+
+ Common:
+
+ - ``YYYY``
+ - ``YYYY-MM`` or ``YYYYMM``
+ - ``YYYY-MM-DD`` or ``YYYYMMDD``
+
+ Uncommon:
+
+ - ``YYYY-Www`` or ``YYYYWww`` - ISO week (day defaults to 0)
+ - ``YYYY-Www-D`` or ``YYYYWwwD`` - ISO week and day
+
+ The ISO week and day numbering follows the same logic as
+ :func:`datetime.date.isocalendar`.
+
+ Supported time formats are:
+
+ - ``hh``
+ - ``hh:mm`` or ``hhmm``
+ - ``hh:mm:ss`` or ``hhmmss``
+ - ``hh:mm:ss.ssssss`` (Up to 6 sub-second digits)
+
+ Midnight is a special case for `hh`, as the standard supports both
+ 00:00 and 24:00 as a representation. The decimal separator can be
+ either a dot or a comma.
+
+
+ .. caution::
+
+ Support for fractional components other than seconds is part of the
+ ISO-8601 standard, but is not currently implemented in this parser.
+
+ Supported time zone offset formats are:
+
+ - `Z` (UTC)
+ - `±HH:MM`
+ - `±HHMM`
+ - `±HH`
+
+ Offsets will be represented as :class:`dateutil.tz.tzoffset` objects,
+ with the exception of UTC, which will be represented as
+ :class:`dateutil.tz.tzutc`. Time zone offsets equivalent to UTC (such
+ as `+00:00`) will also be represented as :class:`dateutil.tz.tzutc`.

+ As of version 2.7.0, the strictness of the parser should not be
+ considered a stable part of the contract. Any valid ISO-8601 string
+ that parses correctly with the default settings will continue to

+ currently fail (e.g. ``2017-01-01T00:00+00:00:00``) are not

+class relativedelta(object):
+ """
+ The relativedelta type is designed to be applied to an existing datetime and
+ can replace specific components of that datetime, or represents an interval
+ of time.
+
+ It is based on the specification of the excellent work done by M.-A. Lemburg
+ in his
+ `mx.DateTime <https://www.egenix.com/products/python/mxBase/mxDateTime/>`_ extension.
+ However, notice that this type does *NOT* implement the same algorithm as
+ his work. Do *NOT* expect it to behave like mx.DateTime's counterpart.
+
+ There are two different ways to build a relativedelta instance. The
+ first one is passing it two date/datetime classes::
+
+ relativedelta(datetime1, datetime2)
+
+ The second one is passing it any number of the following keyword arguments::
+
+ relativedelta(arg1=x,arg2=y,arg3=z...)
+
+ year, month, day, hour, minute, second, microsecond:
+ Absolute information (argument is singular); adding or subtracting a
+ relativedelta with absolute information does not perform an arithmetic
+ operation, but rather REPLACES the corresponding value in the
+ original datetime with the value(s) in relativedelta.
+
+ years, months, weeks, days, hours, minutes, seconds, microseconds:
+ Relative information, may be negative (argument is plural); adding
+ or subtracting a relativedelta with relative information performs
+ the corresponding arithmetic operation on the original datetime value
+ with the information in the relativedelta.
+
+ weekday:
+ One of the weekday instances (MO, TU, etc) available in the
+ relativedelta module. These instances may receive a parameter N,
+ specifying the Nth weekday, which could be positive or negative
+ (like MO(+1) or MO(-2)). Not specifying it is the same as specifying
+ +1. You can also use an integer, where 0=MO. This argument is always
+ relative e.g. if the calculated date is already Monday, using MO(1)
+ or MO(-1) won't change the day. To effectively make it absolute, use
+ it in combination with the day argument (e.g. day=1, MO(1) for first
+ Monday of the month).
+
+ leapdays:
+ Will add given days to the date found, if year is a leap
+ year, and the date found is post 28 of february.
+
+ yearday, nlyearday:
+ Set the yearday or the non-leap year day (jump leap days).
+ These are converted to day/month/leapdays information.
+
+ There are relative and absolute forms of the keyword
+ arguments. The plural is relative, and the singular is
+ absolute. For each argument in the order below, the absolute form
+ is applied first (by setting each attribute to that value) and
+ then the relative form (by adding the value to the attribute).
+
+ The order of attributes considered when this relativedelta is
+ added to a datetime is:
+
+ 1. Year
+ 2. Month
+ 3. Day
+ 4. Hours
+ 5. Minutes
+ 6. Seconds
+ 7. Microseconds
+
+ Finally, weekday is applied, using the rule described above.
+
+ For example
+
+ >>> from datetime import datetime
+ >>> from dateutil.relativedelta import relativedelta, MO
+ >>> dt = datetime(2018, 4, 9, 13, 37, 0)
+ >>> delta = relativedelta(hours=25, day=1, weekday=MO(1))
+ >>> dt + delta
+ datetime.datetime(2018, 4, 2, 14, 37)
+
+ First, the day is set to 1 (the first of the month), then 25 hours
+ are added, to get to the 2nd day and 14th hour, finally the
+ weekday is applied, but since the 2nd is already a Monday there is
+ no effect.

+ """
+ That's the base of the rrule operation. It accepts all the keywords
+ defined in the RFC as its constructor parameters (except byday,
+ which was renamed to byweekday) and more. The constructor prototype is::
+
+ rrule(freq)
+
+ Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY,
+ or SECONDLY.
+
+ .. note::
+ Per RFC section 3.3.10, recurrence instances falling on invalid dates
+ and times are ignored rather than coerced:
+
+ Recurrence rules may generate recurrence instances with an invalid
+ date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM
+ on a day where the local time is moved forward by an hour at 1:00
+ AM). Such recurrence instances MUST be ignored and MUST NOT be
+ counted as part of the recurrence set.
+
+ This can lead to possibly surprising behavior when, for example, the
+ start date occurs at the end of the month:
+
+ >>> from dateutil.rrule import rrule, MONTHLY
+ >>> from datetime import datetime
+ >>> start_date = datetime(2014, 12, 31)
+ >>> list(rrule(freq=MONTHLY, count=4, dtstart=start_date))
+ ... # doctest: +NORMALIZE_WHITESPACE
+ [datetime.datetime(2014, 12, 31, 0, 0),
+ datetime.datetime(2015, 1, 31, 0, 0),
+ datetime.datetime(2015, 3, 31, 0, 0),
+ datetime.datetime(2015, 5, 31, 0, 0)]
+
+ Additionally, it supports the following keyword arguments:
+
+ :param dtstart:
+ The recurrence start. Besides being the base for the recurrence,
+ missing parameters in the final recurrence instances will also be
+ extracted from this date. If not given, datetime.now() will be used
+ instead.
+ :param interval:
+ The interval between each freq iteration. For example, when using
+ YEARLY, an interval of 2 means once every two years, but with HOURLY,
+ it means once every two hours. The default interval is 1.
+ :param wkst:
+ The week start day. Must be one of the MO, TU, WE constants, or an
+ integer, specifying the first day of the week. This will affect
+ recurrences based on weekly periods. The default week start is got
+ from calendar.firstweekday(), and may be modified by
+ calendar.setfirstweekday().
+ :param count:
+ If given, this determines how many occurrences will be generated.
+
+ .. note::
+ As of version 2.5.0, the use of the keyword ``until`` in conjunction
+ with ``count`` is deprecated, to make sure ``dateutil`` is fully
+ compliant with `RFC-5545 Sec. 3.3.10 <https://tools.ietf.org/
+ html/rfc5545#section-3.3.10>`_. Therefore, ``until`` and ``count``
+ **must not** occur in the same call to ``rrule``.
+ :param until:
+ If given, this must be a datetime instance specifying the upper-bound
+ limit of the recurrence. The last recurrence in the rule is the greatest
+ datetime that is less than or equal to the value specified in the
+ ``until`` parameter.
+
+ .. note::
+ As of version 2.5.0, the use of the keyword ``until`` in conjunction
+ with ``count`` is deprecated, to make sure ``dateutil`` is fully
+ compliant with `RFC-5545 Sec. 3.3.10 <https://tools.ietf.org/
+ html/rfc5545#section-3.3.10>`_. Therefore, ``until`` and ``count``
+ **must not** occur in the same call to ``rrule``.
+ :param bysetpos:
+ If given, it must be either an integer, or a sequence of integers,
+ positive or negative. Each given integer will specify an occurrence
+ number, corresponding to the nth occurrence of the rule inside the
+ frequency period. For example, a bysetpos of -1 if combined with a
+ MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will
+ result in the last work day of every month.
+ :param bymonth:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the months to apply the recurrence to.
+ :param bymonthday:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the month days to apply the recurrence to.
+ :param byyearday:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the year days to apply the recurrence to.
+ :param byeaster:
+ If given, it must be either an integer, or a sequence of integers,
+ positive or negative. Each integer will define an offset from the
+ Easter Sunday. Passing the offset 0 to byeaster will yield the Easter
+ Sunday itself. This is an extension to the RFC specification.
+ :param byweekno:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the week numbers to apply the recurrence to. Week numbers
+ have the meaning described in ISO8601, that is, the first week of
+ the year is that containing at least four days of the new year.
+ :param byweekday:
+ If given, it must be either an integer (0 == MO), a sequence of
+ integers, one of the weekday constants (MO, TU, etc), or a sequence
+ of these constants. When given, these variables will define the
+ weekdays where the recurrence will be applied. It's also possible to
+ use an argument n for the weekday instances, which will mean the nth
+ occurrence of this weekday in the period. For example, with MONTHLY,
+ or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the
+ first friday of the month where the recurrence happens. Notice that in
+ the RFC documentation, this is specified as BYDAY, but was renamed to
+ avoid the ambiguity of that keyword.
+ :param byhour:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the hours to apply the recurrence to.
+ :param byminute:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the minutes to apply the recurrence to.
+ :param bysecond:
+ If given, it must be either an integer, or a sequence of integers,
+ meaning the seconds to apply the recurrence to.
+ :param cache:
+ If given, it must be a boolean value specifying to enable or disable
+ caching of results. If you will use the same rrule instance multiple
+ times, enabling caching will improve the performance considerably.

+
+ .. note::
+
+ Only construct a ``tzfile`` directly if you have a specific timezone
+ file on disk that you want to read into a Python ``tzinfo`` object.
+ If you want to get a ``tzfile`` representing a specific IANA zone,
+ (e.g. ``'America/New_York'``), you should call
+ :func:`dateutil.tz.gettz` with the zone identifier.
+
+
+ **Examples:**
+
+ Using the US Eastern time zone as an example, we can see that a ``tzfile``
+ provides time zone information for the standard Daylight Saving offsets:
+
+ .. testsetup:: tzfile
+
+ from dateutil.tz import gettz
+ from datetime import datetime
+
+ .. doctest:: tzfile
+
+ >>> NYC = gettz('America/New_York')
+ >>> NYC
+ tzfile('/usr/share/zoneinfo/America/New_York')
+
+ >>> print(datetime(2016, 1, 3, tzinfo=NYC)) # EST

+
+ >>> print(datetime(2016, 7, 7, tzinfo=NYC)) # EDT
+ 2016-07-07 00:00:00-04:00
+
+
+ The ``tzfile`` structure contains a fully history of the time zone,
+ so historical dates will also have the right offsets. For example, before
+ the adoption of the UTC standards, New York used local solar mean time:
+
+ .. doctest:: tzfile
+
+ >>> print(datetime(1901, 4, 12, tzinfo=NYC)) # LMT
+ 1901-04-12 00:00:00-04:56
+
+ And during World War II, New York was on "Eastern War Time", which was a
+ state of permanent daylight saving time:
+
+ .. doctest:: tzfile
+
+ >>> print(datetime(1944, 2, 7, tzinfo=NYC)) # EWT

+
Introduction
+This documents Python support for hosting ISAPI exensions and filters inside
+Microsoft Internet Information Server (IIS). It assumes a basic understanding
+of the ISAPI filter and extension mechanism.
+
+In summary, to implement a filter or extension, you provide a Python module
+which defines a Filter and/or Extension class. Once your class has been
+loaded, IIS/ISAPI will, via an extension DLL, call methods on your class.
+
+A filter and a class instance need only provide 3 methods - for filters they
+are called GetFilterVersion, HttpFilterProc and
+TerminateFilter. For extensions they
+are named GetExtensionVersion, HttpExtensionProc and
+TerminateExtension. If you are familiar with writing ISAPI
+extensions in C/C++, these names and their purpose will be familiar.
+
+Most of the work is done in the HttpFilterProc and
+HttpExtensionProc methods. These both take a single
+parameter - an HTTP_FILTER_CONTEXT and
+EXTENSION_CONTROL_BLOCK
+object respectively.
+
+In addition to these components, there is an 'isapi' package, containing
+support facilities (base-classes, exceptions, etc) which can be leveraged
+by the extension.
+
+
Base classes
+There are a number of base classes provided to make writing extensions a little
+simpler. Of particular note is isapi.threaded_extension.ThreadPoolExtension.
+This implements a thread-pool and informs IIS that the request is progressing
+in the background. Your sub-class need only provide a Dispatch
+method, which is called on one of the worker threads rather than the thread
+that the request came in on.
+
+There is base-class for a filter in isapi.simple, but there is no
+equivilent threaded filter - filters work under a different model, where
+background processing is not possible.
+
Samples
+Please see the isapi/samples directory for some sample filters
+and extensions.
+
+Implementation
+A Python ISAPI filter extension consists of 2 main components:
+
+A DLL used by ISAPI to interface with Python.
+A Python script used by that DLL to implement the filter or extension
+functionality
+
+
+Extension DLL
+The DLL is usually managed automatically by the isapi.install module. As the
+Python script for the extension is installed, a generic DLL provided with
+the isapi package is installed next to the script, and IIS configured to
+use this DLL.
+
+The name of the DLL always has the same base name as the Python script, but
+with a leading underscore (_), and an extension of .dll. For example, the
+sample "redirector.py" will, when installed, have "_redirector.dll" created
+in the same directory.
+
+The Python script may provide 2 entry points - methods named __FilterFactory__
+and __ExtensionFactory__, both taking no arguments and returning a filter or
+extension object.
+
+Using py2exe and the isapi package
+You can instruct py2exe to create a 'frozen' Python ISAPI filter/extension.
+In this case, py2exe will create a package with everything you need in one
+directory, and the Python source file embedded in the .zip file.
+
+In general, you will want to build a seperate installation executable along
+with the ISAPI extension. This executable will be built from the same script.
+See the ISAPI sample in the py2exe distribution.

+In this directory you will find examples of ISAPI filters and extensions.
+
+The filter loading mechanism works like this:
+* IIS loads the special Python "loader" DLL. This DLL will generally have a
+ leading underscore as part of its name.
+* This loader DLL looks for a Python module, by removing the first letter of
+ the DLL base name.
+
+This means that an ISAPI extension module consists of 2 key files - the loader
+DLL (eg, "_MyIISModule.dll", and a Python module (which for this example
+would be "MyIISModule.py")
+
+When you install an ISAPI extension, the installation code checks to see if
+there is a loader DLL for your implementation file - if one does not exist,

+# This extension demonstrates some advanced features of the Python ISAPI
+# framework.
+# We demonstrate:
+# * Reloading your Python module without shutting down IIS (eg, when your
+# .py implementation file changes.)
+# * Custom command-line handling - both additional options and commands.
+# * Using a query string - any part of the URL after a '?' is assumed to
+# be "variable names" separated by '&' - we will print the values of
+# these server variables.
+# * If the tail portion of the URL is "ReportUnhealthy", IIS will be
+# notified we are unhealthy via a HSE_REQ_REPORT_UNHEALTHY request.
+# Whether this is acted upon depends on if the IIS health-checking
+# tools are installed, but you should always see the reason written
+# to the Windows event log - see the IIS documentation for more.

+# Notes on reloading
+# If your HttpFilterProc or HttpExtensionProc functions raises
+# 'isapi.InternalReloadException', the framework will not treat it
+# as an error but instead will terminate your extension, reload your
+# extension module, re-initialize the instance, and re-issue the request.
+# The Initialize functions are called with None as their param. The
+# return code from the terminate function is ignored.
+#
+# This is all the framework does to help you. It is up to your code
+# when you raise this exception. This sample uses a Win32 "find
+# notification". Whenever windows tells us one of the files in the
+# directory has changed, we check if the time of our source-file has
+# changed, and set a flag. Next imcoming request, we check the flag and
+# raise the special exception if set.
+#
+# The end result is that the module is automatically reloaded whenever
+# the source-file changes - you need take no further action to see your
+# changes reflected in the running server.
+
+# The framework only reloads your module - if you have libraries you
+# depend on and also want reloaded, you must arrange for this yourself.
+# One way of doing this would be to special case the import of these
+# modules. Eg:
+# --
+# try:
+# my_module = reload(my_module) # module already imported - reload it
+# except NameError:
+# import my_module # first time around - import it.
+# --
+# When your module is imported for the first time, the NameError will
+# be raised, and the module imported. When the ISAPI framework reloads
+# your module, the existing module will avoid the NameError, and allow
+# you to reload that module.

+
+pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
+
+Please take a look at our documentation for how to install and use pip:
+
+* `Installation`_
+* `Usage`_
+
+We release updates regularly, with a new version every 3 months. Find more details in our documentation:
+
+* `Release notes`_
+* `Release process`_
+
+In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
+
+**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
+
+If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
+
+* `Issue tracking`_
+* `Discourse channel`_
+* `User IRC`_
+
+If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:
+
+* `GitHub page`_
+* `Development documentation`_
+* `Development mailing list`_
+* `Development IRC`_

+ # a *different* version of Python the entry points will be wrong. The
+ # correct fix for this is to enhance the metadata to be able to describe
+ # such versioned entry points, but that won't happen till Metadata 2.0 is
+ # available.
+ # In the meantime, projects using versioned entry points will either have
+ # incorrect versioned entry points, or they will not be able to distribute
+ # "universal" wheels (i.e., they will need a wheel per Python version).
+ #
+ # Because setuptools and pip are bundled with _ensurepip and virtualenv,
+ # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we

+ 3. We return None for the underlying InstallRequirement, as the base
+ candidate will provide it, and we don't want to end up with duplicates.
+
+ The dependency on the base candidate is needed so that the resolver can't
+ decide that it should recommend foo[extra1] version 1.0 and foo[extra2]
