    Not installed by setup.py (contributed by Ross Gammon, issue #383).
  * replace tabs with spaces by running reindent.py on all *.py and *.pyx files
    (issue #378).
+ * refactor netCDF4_utils and netCDF4 module into netCDF4 package.
+   Refactoring effectively removes netCDF4 utils private attributes from
+   netCDF4 namespace, so has the potential to break code using private
+   attributes (issue #409).

U{netCDF version 4\n<http://www.unidata.ucar.edu/software/netcdf/netcdf-4>} has many features\nnot found in earlier versions of the library and is implemented on top of\nU{HDF5 <http://www.hdfgroup.org/HDF5>}. This module can read and write\nfiles in both the new netCDF 4 and the old netCDF 3 format, and can create\nfiles that are readable by HDF5 clients. The API modelled after\nU{Scientific.IO.NetCDF\n<http://dirac.cnrs-orleans.fr/plone/software/scientificpython/>}, and should be\nfamiliar to users of that module.\n\nMost new features of netCDF 4 are implemented, such as multiple\nunlimited dimensions, groups and zlib data compression.  All the new\nnumeric data types (such as 64 bit and unsigned integer types) are\nimplemented. Compound and variable length (vlen) data types are supported,\nbut the enum and opaque data types are not. Mixtures of compound and vlen\ndata types (compound types containing vlens, and vlens containing compound\ntypes) are not supported.\n\nDownload\n========\n\n - Latest bleeding-edge code from the U{github repository\n   <http://github.com/Unidata/netcdf4-python>}.\n - Latest U{releases <https://pypi.python.org/pypi/netCDF4>}\n   (source code and windows installers).\n\nRequires\n========\n\n - Python 2.5 or later (python 3 works too).\n - numpy array module U{http://numpy.scipy.org}, version 1.7.0 or later.\n - U{Cython <http://cython.org>}, version 0.19 or later, is optional - if it is installed setup.py will\n   use it to recompile the Cython source code into C, using conditional compilation\n   to enable features in the netCDF API that have been added since version 4.1.1.  If\n   Cython is not installed, these features (such as the ability to rename Group objects)\n   will be disabled to preserve backward compatibility with older versions of the netCDF\n   library.\n - For python < 2.7, the ordereddict module U{http://python.org/pypi/ordereddict}.""\n - The HDF5 C library version 1.8.4-patch1 or higher (1.8.8 or higher\n recommended) from U{ftp://ftp.hdfgroup.org/HDF5/current/src}.\n Be sure to build with 'C{--enable-hl --enable-shared}'.\n - U{Libcurl <http://curl.haxx.se/libcurl/>}, if you want\n U{OPeNDAP<http://opendap.org/>} support.\n - U{HDF4 <http://www.hdfgroup.org/products/hdf4/>}, if you want\n to be able to read HDF4 \"Scientific Dataset\" (SD) files.\n - The netCDF-4 C library from U{ftp://ftp.unidata.ucar.edu/pub/netcdf}.\n Version 4.1.1 or higher is required (4.2 or higher recommended).\n Be sure to build with 'C{--enable-netcdf-4 --enable-shared}', and set\n C{CPPFLAGS=\"-I $HDF5_DIR/include\"} and C{LDFLAGS=\"-L $HDF5_DIR/lib\"},\n where C{$HDF5_DIR} is the directory where HDF5 was installed.\n If you want U{OPeNDAP<http://opendap.org/>} support, add 'C{--enable-dap}'.\n If you want HDF4 SD support, add 'C{--enable-hdf4}' and add\n the location of the HDF4 headers and library to C{CPPFLAGS} and C{LDFLAGS}.\n\n\nInstall\n=======\n\n - install the requisite python modules and C libraries (see above). It's\n easiest if all the C libs are built as shared libraries.\n - By default, the utility C{nc-config}, installed with netcdf 4.1.2 or higher,\n will be run used to determine where all the dependencies live.\n - If C{nc-config} is not in your default C{PATH}, rename the\n file C{setup.cfg.template} to C{setup.cfg}, then edit\n in a text editor (follow the instructions in the comments).\n In addition to specifying the path to C{nc-config},\n you can manually set the paths to all the libraries and their include files\n (in case C{nc-config} does not do the right thing).\n - run C{python setup.py build}, then C{python setup.py install} (as root if\n necessary).\n - run the tests in the 'test' directory by running C{python run_all.py}.\n\nTutorial\n========\n\n1) Creating/Opening/Closing a netCDF file\n-----------------------------------------\n\nTo create a netCDF file from python, you simply call th""e L{Dataset}\nconstructor. This is also the method used to open an existing netCDF\nfile.  If the file is open for write access (C{w, r+} or C{a}), you may\nwrite any type of data including new dimensions, groups, variables and\nattributes.  netCDF files come in several flavors (C{NETCDF3_CLASSIC,\nNETCDF3_64BIT, NETCDF4_CLASSIC}, and C{NETCDF4}). The first two flavors\nare supported by version 3 of the netCDF library. C{NETCDF4_CLASSIC}\nfiles use the version 4 disk format (HDF5), but do not use any features\nnot found in the version 3 API. They can be read by netCDF 3 clients\nonly if they have been relinked against the netCDF 4 library. They can\nalso be read by HDF5 clients. C{NETCDF4} files use the version 4 disk\nformat (HDF5) and use the new features of the version 4 API.  The\nC{netCDF4} module can read and write files in any of these formats. When\ncreating a new file, the format may be specified using the C{format}\nkeyword in the C{Dataset} constructor.  The default format is\nC{NETCDF4}. To see how a given file is formatted, you can examine the\nC{data_model} L{Dataset} attribute.  Closing the netCDF file is\naccomplished via the L{close<Dataset.close>} method of the L{Dataset}\ninstance.\n\nHere's an example:\n\n>>> from netCDF4 import Dataset\n>>> rootgrp = Dataset('test.nc', 'w', format='NETCDF4')\n>>> print rootgrp.data_model\nNETCDF4\n>>>\n>>> rootgrp.close()\n\nRemote U{OPeNDAP<http://opendap.org>}-hosted datasets can be accessed for\nreading over http if a URL is provided to the L{Dataset} constructor instead of a\nfilename.  However, this requires that the netCDF library be built with\nOPenDAP support, via the C{--enable-dap} configure option (added in\nversion 4.0.1).\n\n\n2) Groups in a netCDF file\n--------------------------\n\nnetCDF version 4 added support for organizing data in hierarchical\ngroups, which are analagous to directories in a filesystem. Groups serve\nas containers for variables, dimensions and attributes, as well as other\ngro""ups.  A C{netCDF4.Dataset} defines creates a special group, called\nthe 'root group', which is similar to the root directory in a unix\nfilesystem.  To create L{Group} instances, use the\nL{createGroup<Dataset.createGroup>} method of a L{Dataset} or L{Group}\ninstance. L{createGroup<Dataset.createGroup>} takes a single argument, a\npython string containing the name of the new group. The new L{Group}\ninstances contained within the root group can be accessed by name using\nthe C{groups} dictionary attribute of the L{Dataset} instance.  Only\nC{NETCDF4} formatted files support Groups, if you try to create a Group\nin a netCDF 3 file you will get an error message.\n\n>>> rootgrp = Dataset('test.nc', 'a')\n>>> fcstgrp = rootgrp.createGroup('forecasts')\n>>> analgrp = rootgrp.createGroup('analyses')\n>>> print rootgrp.groups\nOrderedDict([('forecasts', <netCDF4.Group object at 0x1b4b7b0>),\n             ('analyses', <netCDF4.Group object at 0x1b4b970>)])\n>>>\n\nGroups can exist within groups in a L{Dataset}, just as directories\nexist within directories in a unix filesystem. Each L{Group} instance\nhas a C{'groups'} attribute dictionary containing all of the group\ninstances contained within that group. Each L{Group} instance also has a\nC{'path'} attribute that contains a simulated unix directory path to\nthat group.\n\nHere's an example that shows how to navigate all the groups in a\nL{Dataset}. The function C{walktree} is a Python generator that is used\nto walk the directory tree. Note that printing the L{Dataset} or L{Group}\nobject yields summary information about it's contents.\n\n>>> fcstgrp1 = fcstgrp.createGroup('model1')\n>>> fcstgrp2 = fcstgrp.createGroup('model2')\n>>> def walktree(top):\n>>>     values = top.groups.values()\n>>>     yield values\n>>>     for value in top.groups.values():\n>>>         for children in walktree(value):\n>>>             yield children\n>>> print rootgrp\n>>> for children in walktree(rootgrp):\n>>>      for child in children:""\n>>>          print child\n<type 'netCDF4.Dataset'>\nroot group (NETCDF4 file format):\n    dimensions:\n    variables:\n        groups: forecasts, analyses\n<type 'netCDF4.Group'>\ngroup /forecasts:\n    dimensions:\n    variables:\n    groups: model1, model2\n<type 'netCDF4.Group'>\ngroup /analyses:\n    dimensions:\n    variables:\n    groups:\n<type 'netCDF4.Group'>\ngroup /forecasts/model1:\n    dimensions:\n    variables:\n    groups:\n<type 'netCDF4.Group'>\ngroup /forecasts/model2:\n    dimensions:\n    variables:\n    groups:\n>>>\n\n3) Dimensions in a netCDF file\n------------------------------\n\nnetCDF defines the sizes of all variables in terms of dimensions, so\nbefore any variables can be created the dimensions they use must be\ncreated first. A special case, not often used in practice, is that of a\nscalar variable, which has no dimensions. A dimension is created using\nthe L{createDimension<Dataset.createDimension>} method of a L{Dataset}\nor L{Group} instance. A Python string is used to set the name of the\ndimension, and an integer value is used to set the size. To create an\nunlimited dimension (a dimension that can be appended to), the size\nvalue is set to C{None} or 0. In this example, there both the C{time} and\nC{level} dimensions are unlimited.  Having more than one unlimited\ndimension is a new netCDF 4 feature, in netCDF 3 files there may be only\none, and it must be the first (leftmost) dimension of the variable.\n\n>>> level = rootgrp.createDimension('level', None)\n>>> time = rootgrp.createDimension('time', None)\n>>> lat = rootgrp.createDimension('lat', 73)\n>>> lon = rootgrp.createDimension('lon', 144)\n\n\nAll of the L{Dimension} instances are stored in a python dictionary.\n\n>>> print rootgrp.dimensions\nOrderedDict([('level', <netCDF4.Dimension object at 0x1b48030>),\n             ('time', <netCDF4.Dimension object at 0x1b481c0>),\n             ('lat', <netCDF4.Dimension object at 0x1b480f8>),\n             ('lon', <netCDF4.Dime""nsion object at 0x1b48a08>)])\n>>>\n\nCalling the python C{len} function with a L{Dimension} instance returns\nthe current size of that dimension.\nThe L{isunlimited<Dimension.isunlimited>} method of a L{Dimension} instance\ncan be used to determine if the dimensions is unlimited, or appendable.\n\n>>> print len(lon)\n144\n>>> print len.is_unlimited()\nFalse\n>>> print time.is_unlimited()\nTrue\n>>>\n\nPrinting the L{Dimension} object\nprovides useful summary info, including the name and length of the dimension,\nand whether it is unlimited.\n\n>>> for dimobj in rootgrp.dimensions.values():\n>>>    print dimobj\n<type 'netCDF4.Dimension'> (unlimited): name = 'level', size = 0\n<type 'netCDF4.Dimension'> (unlimited): name = 'time', size = 0\n<type 'netCDF4.Dimension'>: name = 'lat', size = 73\n<type 'netCDF4.Dimension'>: name = 'lon', size = 144\n<type 'netCDF4.Dimension'> (unlimited): name = 'time', size = 0\n>>>\n\nL{Dimension} names can be changed using the\nL{renameDimension<Dataset.renameDimension>} method of a L{Dataset} or\nL{Group} instance.\n\n4) Variables in a netCDF file\n-----------------------------\n\nnetCDF variables behave much like python multidimensional array objects\nsupplied by the U{numpy module <http://numpy.scipy.org>}. However,\nunlike numpy arrays, netCDF4 variables can be appended to along one or\nmore 'unlimited' dimensions. To create a netCDF variable, use the\nL{createVariable<Dataset.createVariable>} method of a L{Dataset} or\nL{Group} instance. The L{createVariable<Dataset.createVariable>} method\nhas two mandatory arguments, the variable name (a Python string), and\nthe variable datatype. The variable's dimensions are given by a tuple\ncontaining the dimension names (defined previously with\nL{createDimension<Dataset.createDimension>}). To create a scalar\nvariable, simply leave out the dimensions keyword. The variable\nprimitive datatypes correspond to the dtype attribute of a numpy array.\nYou can specify the datatype as a numpy dty""pe object, or anything that\ncan be converted to a numpy dtype object.  Valid datatype specifiers\ninclude: C{'f4'} (32-bit floating point), C{'f8'} (64-bit floating\npoint), C{'i4'} (32-bit signed integer), C{'i2'} (16-bit signed\ninteger), C{'i8'} (64-bit singed integer), C{'i1'} (8-bit signed\ninteger), C{'u1'} (8-bit unsigned integer), C{'u2'} (16-bit unsigned\ninteger), C{'u4'} (32-bit unsigned integer), C{'u8'} (64-bit unsigned\ninteger), or C{'S1'} (single-character string).  The old Numeric\nsingle-character typecodes (C{'f'},C{'d'},C{'h'},\nC{'s'},C{'b'},C{'B'},C{'c'},C{'i'},C{'l'}), corresponding to\n(C{'f4'},C{'f8'},C{'i2'},C{'i2'},C{'i1'},C{'i1'},C{'S1'},C{'i4'},C{'i4'}),\nwill also work. The unsigned integer types and the 64-bit integer type\ncan only be used if the file format is C{NETCDF4}.\n\nThe dimensions themselves are usually also defined as variables, called\ncoordinate variables. The L{createVariable<Dataset.createVariable>}\nmethod returns an instance of the L{Variable} class whose methods can be\nused later to access and set variable data and attributes.\n\n>>> times = rootgrp.createVariable('time','f8',('time',))\n>>> levels = rootgrp.createVariable('level','i4',('level',))\n>>> latitudes = rootgrp.createVariable('latitude','f4',('lat',))\n>>> longitudes = rootgrp.createVariable('longitude','f4',('lon',))\n>>> # two dimensions unlimited.\n>>> temp = rootgrp.createVariable('temp','f4',('time','level','lat','lon',))\n\nAll of the variables in the L{Dataset} or L{Group} are stored in a\nPython dictionary, in the same way as the dimensions:\n\n>>> print rootgrp.variables\nOrderedDict([('time', <netCDF4.Variable object at 0x1b4ba70>),\n             ('level', <netCDF4.Variable object at 0x1b4bab0>),\n             ('latitude', <netCDF4.Variable object at 0x1b4baf0>),\n             ('longitude', <netCDF4.Variable object at 0x1b4bb30>),\n             ('temp', <netCDF4.Variable object at 0x1b4bb70>)])\n>>>\n\nTo get summary info on a L{Variable} insta""nce in an interactive session, just print it.\n\n>>> print rootgrp.variables['temp']\n<type 'netCDF4.Variable'>\nfloat32 temp(time, level, lat, lon)\n    least_significant_digit: 3\n    units: K\nunlimited dimensions: time, level\ncurrent shape = (0, 0, 73, 144)\n>>>\n\nL{Variable} names can be changed using the\nL{renameVariable<Dataset.renameVariable>} method of a L{Dataset}\ninstance.\n\n\n5) Attributes in a netCDF file\n------------------------------\n\nThere are two types of attributes in a netCDF file, global and variable.\nGlobal attributes provide information about a group, or the entire\ndataset, as a whole. L{Variable} attributes provide information about\none of the variables in a group. Global attributes are set by assigning\nvalues to L{Dataset} or L{Group} instance variables. L{Variable}\nattributes are set by assigning values to L{Variable} instances\nvariables. Attributes can be strings, numbers or sequences.

Slices behave as usual, being specified as a\nC{start:stop:step} triplet. Using a scalar integer index C{i} takes the ith\nelement and reduces the rank of the output array by one. Boolean array and\ninteger sequence indexing behaves differently for netCDF variables\nthan for numpy arrays.  Only 1-d boolean arrays and integer sequences are\nallowed, and these indices work independently along each dimension (similar\nto the way vector subscripts work in fortran).  This means that\n\n>>> temp[0, 0, [0,1,2,3], [0,1,2,3]]\n\nreturns an array of shape (4,4) when slicing a netCDF variable, but for a\nnumpy array it returns an array of shape (4,).\nSimilarly, a netCDF variable of shape C{(2,3,4,5)} indexed\nwith C{[0, array([True, False, True]), array([False, True, True, True]), :]}\nwould return a C{(2, 3, 5)} array. In NumPy, this would raise an error since\nit would be equivalent to C{[0, [0,1], [1,2,3], :]}. When slicing with integer\nsequences, the indices must be sorted in increasing order and contain no duplicates.\nWhile this behaviour may cause some confusion for those used to NumPy's 'fancy indexing' rules,\nit provides a very powerful way to extract data from multidimensional netCDF\nvariables by using logical operations on the dimension arrays to create sl""ices.\n\nFor example,\n\n>>> tempdat = temp[::2, [1,3,6], lats>0, lons>0]\n\nwill extract time indices 0,2 and 4, pressure levels\n850, 500 and 200 hPa, all Northern Hemisphere latitudes and Eastern\nHemisphere longitudes, resulting in a numpy array of shape  (3, 3, 36, 71).\n\n>>> print 'shape of fancy temp slice = ',tempdat.shape\nshape of fancy temp slice =  (3, 3, 36, 71)\n>>>\n\nTime coordinate values pose a special challenge to netCDF users.  Most\nmetadata standards (such as CF and COARDS) specify that time should be\nmeasure relative to a fixed date using a certain calendar, with units\nspecified like C{hours since YY:MM:DD hh-mm-ss}.  These units can be\nawkward to deal with, without a utility to convert the values to and\nfrom calendar dates.  The functione called L{num2date} and L{date2num} are\nprovided with this package to do just that.  Here's an example of how they\ncan be used:\n\n>>> # fill in times.\n>>> from datetime import datetime, timedelta\n>>> from netCDF4 import num2date, date2num\n>>> dates = [datetime(2001,3,1)+n*timedelta(hours=12) for n in range(temp.shape[0])]\n>>> times[:] = date2num(dates,units=times.units,calendar=times.calendar)\n>>> print 'time values (in units %s): ' % times.units+'\\n',times[:]\ntime values (in units hours since January 1, 0001):\n[ 17533056.  17533068.  17533080.  17533092.  17533104.]\n>>>\n>>> dates = num2date(times[:],units=times.units,calendar=times.calendar)\n>>> print 'dates corresponding to time values:\\n',dates\ndates corresponding to time values:\n[2001-03-01 00:00:00 2001-03-01 12:00:00 2001-03-02 00:00:00\n 2001-03-02 12:00:00 2001-03-03 00:00:00]\n>>>\n\nL{num2date} converts numeric values of time in the specified C{units}\nand C{calendar} to datetime objects, and L{date2num} does the reverse.\nAll the calendars currently defined in the U{CF metadata convention\n<http://cf-pcmdi.llnl.gov/documents/cf-conventions/>} are supported.\nA function called L{date2index} is also provided which returns the in""dices\nof a netCDF time variable corresponding to a sequence of datetime instances.\n\n\n7) Reading data from a multi-file netCDF dataset.\n-------------------------------------------------\n\nIf you want to read data from a variable that spans multiple netCDF files,\nyou can use the L{MFDataset} class to read the data as if it were\ncontained in a single file. Instead of using a single filename to create\na L{Dataset} instance, create a L{MFDataset} instance with either a list\nof filenames, or a string with a wildcard (which is then converted to\na sorted list of files using the python glob module).\nVariables in the list of files that share the same unlimited\ndimension are aggregated together, and can be sliced across multiple\nfiles.  To illustrate this, let's first create a bunch of netCDF files with\nthe same variable (with the same unlimited dimension).  The files\nmust in be in C{NETCDF3_64BIT}, C{NETCDF3_CLASSIC} or\nC{NETCDF4_CLASSIC format} (C{NETCDF4} formatted multi-file\ndatasets are not supported).\n\n>>> for nfile in range(10):\n>>>     f = Dataset('mftest'+repr(nfile)+'.nc','w',format='NETCDF4_CLASSIC')\n>>>     f.createDimension('x',None)\n>>>     x = f.createVariable('x','i',('x',))\n>>>     x[0:10] = numpy.arange(nfile*10,10*(nfile+1))\n>>>     f.close()\n\nNow read all the files back in at once with L{MFDataset}\n\n>>> from netCDF4 import MFDataset\n>>> f = MFDataset('mftest*nc')\n>>> print f.variables['x'][:]\n[ 0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24\n 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49\n 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74\n 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99]\n>>>\n\nNote that MFDataset can only be used to read, not write, multi-file\ndatasets.\n\n8) Efficient compression of netCDF variables\n--------------------------------------------\n\nData stored in netCDF 4 L{Variable} objects can be ""compressed and\ndecompressed on the fly. The parameters for the compression are\ndetermined by the C{zlib}, C{complevel} and C{shuffle} keyword arguments\nto the L{createVariable<Dataset.createVariable>} method. To turn on\ncompression, set C{zlib=True}.  The C{complevel} keyword regulates the\nspeed and efficiency of the compression (1 being fastest, but lowest\ncompression ratio, 9 being slowest but best compression ratio). The\ndefault value of C{complevel} is 4. Setting C{shuffle=False} will turn\noff the HDF5 shuffle filter, which de-interlaces a block of data before\ncompression by reordering the bytes.  The shuffle filter can\nsignificantly improve compression ratios, and is on by default.  Setting\nC{fletcher32} keyword argument to\nL{createVariable<Dataset.createVariable>} to C{True} (it's C{False} by\ndefault) enables the Fletcher32 checksum algorithm for error detection.\nIt's also possible to set the HDF5 chunking parameters and endian-ness\nof the binary data stored in the HDF5 file with the C{chunksizes}\nand C{endian} keyword arguments to\nL{createVariable<Dataset.createVariable>}.  These keyword arguments only\nare relevant for C{NETCDF4} and C{NETCDF4_CLASSIC} files (where the\nunderlying file format is HDF5) and are silently ignored if the file\nformat is C{NETCDF3_CLASSIC} or C{NETCDF3_64BIT},\n\nIf your data only has a certain number of digits of precision (say for\nexample, it is temperature data that was measured with a precision of\n0.1 degrees), you can dramatically improve zlib compression by\nquantizing (or truncating) the data using the C{least_significant_digit}\nkeyword argument to L{createVariable<Dataset.createVariable>}. The least\nsignificant digit is the power of ten of the smallest decimal place in\nthe data that is a reliable value. For example if the data has a\nprecision of 0.1, then setting C{least_significant_digit=1} will cause\ndata the data to be quantized using C{numpy.around(scale*data)/scale}, where\nscale = 2**bits, and"" bits is determined so that a precision of 0.1 is\nretained (in this case bits=4).  Effectively, this makes the compression\n'lossy' instead of 'lossless', that is some precision in the data is\nsacrificed for the sake of disk space.\n\nIn our example, try replacing the line\n\n>>> temp = rootgrp.createVariable('temp','f4',('time','level','lat','lon',))\n\nwith\n\n>>> temp = dataset.createVariable('temp','f4',('time','level','lat','lon',),zlib=True)\n\nand then\n\n>>> temp = dataset.createVariable('temp','f4',('time','level','lat','lon',),zlib=True,least_significant_digit=3)\n\nand see how much smaller the resulting files are.\n\n9) Beyond homogenous arrays of a fixed type - compound data types\n-----------------------------------------------------------------\n\nCompound data types map directly to numpy structured (a.k.a 'record'\narrays).  Structured arrays are akin to C structs, or derived types\nin Fortran. They allow for the construction of table-like structures\ncomposed of combinations of other data types, including other\ncompound types. Compound types might be useful for representing multiple\nparameter values at each point on a grid, or at each time and space\nlocation for scattered (point) data. You can then access all the\ninformation for a point by reading one variable, instead of reading\ndifferent parameters from different variables.  Compound data types\nare created from the corresponding numpy data type using the\nL{createCompoundType<Dataset.createCompoundType>} method of a L{Dataset} or L{Group} instance.\nSince there is no native complex data type in netcdf, compound types are handy\nfor storing numpy complex arrays.  Here's an example:\n\n>>> f = Dataset('complex.nc','w')\n>>> size = 3 # length of 1-d complex array\n>>> # create sample complex data.\n>>> datac = numpy.exp(1j*(1.+numpy.linspace(0, numpy.pi, size)))\n>>> # create complex128 compound data type.\n>>> complex128 = numpy.dtype([('real',numpy.float64),('imag',numpy.float64)])\n>>> comp""lex128_t = f.createCompoundType(complex128,'complex128')\n>>> # create a variable with this data type, write some data to it.\n>>> f.createDimension('x_dim',None)\n>>> v = f.createVariable('cmplx_var',complex128_t,'x_dim')\n>>> data = numpy.empty(size,complex128) # numpy structured array\n>>> data['real'] = datac.real; data['imag'] = datac.imag\n>>> v[:] = data # write numpy structured array to netcdf compound var\n>>> # close and reopen the file, check the contents.\n>>> f.close(); f = Dataset('complex.nc')\n>>> v = f.variables['cmplx_var']\n>>> datain = v[:] # read in all the data into a numpy structured array\n>>> # create an empty numpy complex array\n>>> datac2 = numpy.empty(datain.shape,numpy.complex128)\n>>> # .. fill it with contents of structured array.\n>>> datac2.real = datain['real']; datac2.imag = datain['imag']\n>>> print datac.dtype,datac # original data\ncomplex128 [ 0.54030231+0.84147098j -0.84147098+0.54030231j  -0.54030231-0.84147098j]\n>>>\n>>> print datac2.dtype,datac2 # data from file\ncomplex128 [ 0.54030231+0.84147098j -0.84147098+0.54030231j  -0.54030231-0.84147098j]\n>>>\n\nCompound types can be nested, but you must create the 'inner'\nones first. All of the compound types defined for a L{Dataset} or L{Group} are stored in a\nPython dictionary, just like variables and dimensions. As always, printing\nobjects gives useful summary information in an interactive session:\n\n>>> print f\n<type 'netCDF4.Dataset'>\nroot group (NETCDF4 file format):\n    dimensions: x_dim\n    variables: cmplx_var\n    groups:\n<type 'netCDF4.Variable'>\n>>> print f.variables['cmplx_var']\ncompound cmplx_var(x_dim)\ncompound data type: [('real', '<f8'), ('imag', '<f8')]\nunlimited dimensions: x_dim\ncurrent shape = (3,)\n>>> print f.cmptypes\nOrderedDict([('complex128', <netCDF4.CompoundType object at 0x1029eb7e8>)])\n>>> print f.cmptypes['complex128']\n<type 'netCDF4.CompoundType'>: name = 'complex128', numpy dtype = [(u'real','<f8'), (u'imag', '<f8')]\n>>>\n\n10)"" Variable-length (vlen) data types.\n--------------------------------------\n\nNetCDF 4 has support for variable-length or \"ragged\" arrays.  These are arrays\nof variable length sequences having the same type. To create a variable-length\ndata type, use the L{createVLType<Dataset.createVLType>} method\nmethod of a L{Dataset} or L{Group} instance.\n\n>>> f = Dataset('tst_vlen.nc','w')\n>>> vlen_t = f.createVLType(numpy.int32, 'phony_vlen')\n\nThe numpy datatype of the variable-length sequences and the name of the\nnew datatype must be specified. Any of the primitive datatypes can be\nused (signed and unsigned integers, 32 and 64 bit floats, and characters),\nbut compound data types cannot.\nA new variable can then be created using this datatype.\n\n>>> x = f.createDimension('x',3)\n>>> y = f.createDimension('y',4)\n>>> vlvar = f.createVariable('phony_vlen_var', vlen_t, ('y','x'))\n\nSince there is no native vlen datatype in numpy, vlen arrays are represented\nin python as object arrays (arrays of dtype C{object}). These are arrays whose\nelements are Python object pointers, and can contain any type of python object.\nFor this application, they must contain 1-D numpy arrays all of the same type\nbut of varying length.\nIn this case, they contain 1-D numpy C{int32} arrays of random length betwee\n1 and 10.\n\n>>> import random\n>>> data = numpy.empty(len(y)*len(x),object)\n>>> for n in range(len(y)*len(x)):\n>>>    data[n] = numpy.arange(random.randint(1,10),dtype='int32')+1\n>>> data = numpy.reshape(data,(len(y),len(x)))\n>>> vlvar[:] = data\n>>> print 'vlen variable =\\n',vlvar[:]\nvlen variable =\n[[[ 1  2  3  4  5  6  7  8  9 10] [1 2 3 4 5] [1 2 3 4 5 6 7 8]]\n [[1 2 3 4 5 6 7] [1 2 3 4 5 6] [1 2 3 4 5]]\n [[1 2 3 4 5] [1 2 3 4] [1]]\n [[ 1  2  3  4  5  6  7  8  9 10] [ 1  2  3  4  5  6  7  8  9 10]\n  [1 2 3 4 5 6 7 8]]]\n>>> print f\n<type 'netCDF4.Dataset'>\nroot group (NETCDF4 file format):\n    dimensions: x, y\n    variables: phony_vlen_var\n    groups:""\n>>> print f.variables['phony_vlen_var']\n<type 'netCDF4.Variable'>\nvlen phony_vlen_var(y, x)\nvlen data type: int32\nunlimited dimensions:\ncurrent shape = (4, 3)\n>>> print f.VLtypes['phony_vlen']\n<type 'netCDF4.VLType'>: name = 'phony_vlen', numpy dtype = int32\n>>>\n\nNumpy object arrays containing python strings can also be written as vlen\nvariables,  For vlen strings, you don't need to create a vlen data type.\nInstead, simply use the python C{str} builtin (or a numpy string datatype\nwith fixed length greater than 1) when calling the\nL{createVariable<Dataset.createVariable>} method.\n\n>>> z = f.createDimension('z',10)\n>>> strvar = rootgrp.createVariable('strvar', str, 'z')\n\nIn this example, an object array is filled with random python strings with\nrandom lengths between 2 and 12 characters, and the data in the object\narray is assigned to the vlen string variable.\n\n>>> chars = '1234567890aabcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'\n>>> data = numpy.empty(10,'O')\n>>> for n in range(10):\n>>>     stringlen = random.randint(2,12)\n>>>     data[n] = ''.join([random.choice(chars) for i in range(stringlen)])\n>>> strvar[:] = data\n>>> print 'variable-length string variable:\\n',strvar[:]\nvariable-length string variable:\n[aDy29jPt jd7aplD b8t4RM jHh8hq KtaPWF9cQj Q1hHN5WoXSiT MMxsVeq td LUzvVTzj\n 5DS9X8S]\n>>> print f\n<type 'netCDF4.Dataset'>\nroot group (NETCDF4 file format):\n    dimensions: x, y, z\n    variables: phony_vlen_var, strvar\n    groups:\n>>> print f.variables['strvar']\n<type 'netCDF4.Variable'>\nvlen strvar(z)\nvlen data type: <type 'str'>\nunlimited dimensions:\ncurrent size = (10,)\n>>>\n\nIt is also possible to set contents of vlen string variables with numpy arrays\nof any string or unicode data type.

   "\nDataset(self, filename, mode=\"r\", clobber=True, diskless=False, persist=False, keepweakref=False, format='NETCDF4')\n\nA netCDF L{Dataset} is a collection of dimensions, groups, variables and\nattributes. Together they describe the meaning of data and relations among\ndata fields stored in a netCDF file.\n\nB{Parameters:}\n\nB{C{filename}} - Name of netCDF file to hold dataset.\n\nB{Keywords}:\n\nB{C{mode}} - access mode. C{r} means read-only; no data can be\nmodified. C{w} means write; a new file is created, an existing file with\nthe same name is deleted. C{a} and C{r+} mean append (in analogy with\nserial files); an existing file is opened for reading and writing.\nAppending C{s} to modes C{w}, C{r+} or C{a} will enable unbuffered shared\naccess to C{NETCDF3_CLASSIC} or C{NETCDF3_64BIT} formatted files.\nUnbuffered acesss may be useful even if you don't need shared\naccess, since it may be faster for programs that don't access data\nsequentially. This option is ignored for C{NETCDF4} and C{NETCDF4_CLASSIC}\nformatted files.\n\nB{C{clobber}} - if C{True} (default), opening a file with C{mode='w'}\nwill clobber an existing file with the same name.  if C{False}, an\nexception will be raised if a file with the same name already exists.\n\nB{C{format}} - underlying file format (one of C{'NETCDF4',\n'NETCDF4_CLASSIC', 'NETCDF3_CLASSIC'} or C{'NETCDF3_64BIT'}.  Only\nrelevant if C{mode = 'w'} (if C{mode = 'r','a'} or C{'r+'} the file format\nis automatically detected). Default C{'NETCDF4'}, which means the data is\nstored in an HDF5 file, using netCDF 4 API features.  Setting\nC{format='NETCDF4_CLASSIC'} will create an HDF5 file, using only netCDF 3\ncompatibile API features. netCDF 3 clients must be recompiled and linked\nagainst the netCDF 4 library to read files in C{NETCDF4_CLASSIC} format.\nC{'NETCDF3_CLASSIC'} is the classic netCDF 3 file format that does not\nhandle 2+ Gb files very well. C{'NETCDF3_64BIT'} is the 64-bit offset\nversion of the netCDF 3 file format, which fully supports 2+ GB files, but\nis only compatible with clients linked against netCDF version 3.6.0 or\nlater.\n\nC{diskless} - create diskless (in memory) file.  This is an experimental\nfeature added to the C library after the netcdf-4.2 release.\n\nC{persist} - if diskless=True, persist file to disk when closed (default False).\n\nC{keepweakref} - if keepweakref=True, child Dimension and Variable instances will keep weak\nreferences to the parent Dataset or Group object.  Default is False, which\nmeans strong references will be kept.  Having Dimension and Variable instances\nkeep a strong reference to the parent Dataset instance, which in turn keeps a\nreference to child Dimension and Variable instances, creates circular references.\nCircular references complicate garbage collection, which may mean increased\nmemory usage for programs that create may Dataset instances with lots of\nVariables.  Setting keepweakref to True allows Dataset instances to be\ngarbage collected as soon as they go out of scope, potential reducing memory\nusage.  However, in most cases this is not desirable, since the associated\nVariable instances may still be needed, but are rendered unusable when the\nparent Dataset instance is garbage collected.\n\nB{Returns:}\n\na L{Dataset} instance.  All further operations on the netCDF\nDataset are accomplised via L{Dataset} instance methods.\n\nA list of attribute names corresponding to global netCDF attributes\ndefined for the L{Dataset} can be obtained with the L{ncattrs()} method.\nThese attributes can be created by assigning to an attribute of the\nL{Dataset} instance. A dictionary containing all the netCDF attribute\nname/value pairs is provided by the C{__dict__} attribute of a\nL{Dataset} instance.\n\nThe instance variables C{dimensions, variables, groups,\ncmptypes, data_model, disk_format} and C{path} are read-only (and should not be modified by the\nuser).\n\n@ivar dimensions: The C{dimensions} dictionary maps the names of\ndimensions defined for the L{Group} or L{Dataset} to instances of the\nL{Dimension} class.\n\n@ivar variables: The C{variables} dictionary maps the names of variables\ndefined for this L{Dataset} or L{Group} to instances of the L{Variable}\nclass.\n\n@ivar groups: The groups dictionary maps the names of groups created for\nthis L{Dataset} or L{Group} to instances of the L{Group} class (the\nL{Dataset} class is simply a special case of the L{Group} class which\ndescribes the root group in the netCDF file).\n\n@ivar cmptypes: The C{cmptypes} dictionary maps the names of\ncompound types defined for the L{Group} or L{Dataset} to instances of the\nL{CompoundType} class.\n\n@ivar vltypes: The C{vltypes} dictionary maps the names of\nvariable-length types defined for the L{Group} or L{Dataset} to instances of the\nL{VLType} class.\n\n@ivar data_model: The C{data_model} attribute describes the netCDF\ndata model version, one of C{NETCDF3_CLASSIC}, C{NETCDF4},\nC{NETCDF4_CLASSIC} or C{NETCDF3_64BIT}.\n\n@ivar file_format: same as C{data_model}, retained for backwards\ncompatibility.\n\n@ivar disk_format: The C{disk_format} attribute describes the underlying\nfile format, one of C{NETCDF3}, C{HDF5}, C{HDF4},\nC{PNETCDF}, C{DAP2}, C{DAP4} or C{UNDEFINED}. Only available if using\nnetcdf C library version >= 4.3.1, otherwise will always return C{UNDEFINED}.\n\n@ivar path: The C{path} attribute shows the location of the L{Group} in\nthe L{Dataset} in a unix directory format (the names of groups in the\nhierarchy separated by backslashes). A L{Dataset} instance is the root\ngroup, so the path is simply C{'/'}.\n\n@ivar parent:  The C{parent} attribute is a reference to the parent\nL{Group} instance. C{None} for a the root group or L{Dataset} instance", /*tp_doc*/

They are\nanalagous to numpy array objects.\n\nL{Variable} instances should be created using the\nL{createVariable<Dataset.createVariable>} method of a L{Dataset} or\nL{Group} instance, not using this class directly.\n\nB{Parameters:}\n\nB{C{group}} - L{Group} or L{Dataset} instance to associate with variable.\n\nB{C{name}}  - Name of the variable.\n\nB{C{datatype}} - L{Variable} data type. Can be specified by providing a\nnumpy dtype object, or a string that describes a numpy dtype object.\nSupported values, corresponding to C{str} attribute of numpy dtype\nobjects, include C{'f4'} (32-bit floating point), C{'f8'} (64-bit floating\npoint), C{'i4'} (32-bit signed integer), C{'i2'} (16-bit signed integer),\nC{'i8'} (64-bit singed integer), C{'i4'} (8-bit singed integer), C{'i1'}\n(8-bit signed integer), C{'u1'} (8-bit unsigned integer), C{'u2'} (16-bit\nunsigned integer), C{'u4'} (32-bit unsigned integer), C{'u8'} (64-bit\nunsigned integer), or C{'S1'} (single-character string).  From\ncompatibility with Scientific.IO.NetCDF, the old Numeric single character\ntypecodes can also be used (C{'f'} instead of C{'f4'}, C{'d'} instead of\nC{'f8'}, C{'h'} or C{'s'} instead of C{'i2'}, C{'b'} or C{'B'} instead of\nC{'i1'}, C{'c'} instead of C{'S1'}, and C{'i'} or C{'l'} instead of\nC{'i4'}). C{datatype} can also be a L{CompoundType} instance\n(for a structured, or compound array), a L{VLType} instance\n(for a variable-length array), or the python C{str} builtin\n(for a variable-length string array). Numpy string and unicode datatypes with\nlength greater than one are aliases for C{str}.\n\nB{Keywords:}\n\nB{C{dimensions}} - a tuple containing the variable's dimension names\n(defined previously with C{createDimension}). Default is an empty tuple\nwhich means the variable is a scalar (and therefore has no dimensions).\n\nB{C{zlib}} - if C{True}, data assigned to the L{Variable}\ninstance is compressed on disk. Default C{False}.\n\nB{C{complevel}} - the level of zlib compression to use (1 is the fastest,\nbut poorest compression, 9 is the slowest but best compression). Default 4.\nIgnored if C{zlib=False}.\n\nB{C{shuffle}} - if C{True}, the HDF5 shuffle filter is applied\nto improve compression. Default C{True}. Ignored if C{zlib=False}.\n\nB{C{fletcher32}} - if C{True} (default C{False}), the Fletcher32 checksum\nalgorithm is used for error detection.\n\nB{C{contiguous}} - if C{True} (default C{False}), the variable data is\nstored contiguously on disk.  Default C{False}. Setting to C{True} for\na variable with an unlimited dimension will trigger an error.\n\nB{C{chunksizes}} - Can be used to specify the HDF5 chunksizes for each\ndimension of the variable. A detailed discussion of HDF chunking and I/O\nperformance is available U{here\n<http://www.hdfgroup.org/HDF5/doc/H5.user/Chunking.html>}.\nBasically, you want the chunk size for each dimension to match as\nclosely as possible the size of the data block that users will read\nfrom the file. C{chunksizes} cannot be set if C{contiguous=True}.\n\nB{C{endian}} - Can be used to control whether the\ndata is stored in little or big endian format on disk. Possible\nvalues are C{little, big} or C{native} (default). The library\nwill automatically handle endian conversions when the data is read,\nbut if the data is always going to be read on a computer with the\nopposite format as the one used to create the file, there may be\nsome performance advantage to be gained by setting the endian-ness.\nFor netCDF 3 files (that don't use HDF5), only C{endian='native'} is allowed.\n\nThe C{zlib, complevel, shuffle, fletcher32, contiguous} and {chunksizes}\nkeywords are silently ignored for netCDF 3 files that do not use HDF5.\n\nB{C{least_significant_digit}} - If specified, variable data will be\ntruncated (quantized). In conjunction with C{zlib=True} this produces\n'lossy', but significantly more efficient compression. For example, if\nC{least_significant_digit=1}, data will be quantized using\naround(scale*data)/scale, where scale = 2**bits, and bits is determined\nso that a precision of 0.1 is retained (in this case bits=4). Default is\nC{None}, or no quantization.\n\nB{C{fill_value}} - If specified, the default netCDF C{_FillValue} (the\nvalue that the variable gets filled with before any data is written to it)\nis replaced with this value.  If fill_value is set to C{False}, then\nthe variable is not pre-filled. The default netCDF fill values can be found\nin netCDF4.default_fillvals.\n\nB{Returns:}\n\na L{Variable} instance.  All further operations on the netCDF Variable are\naccomplised via L{Variable} instance methods.\n\nA list of attribute names corresponding to netCDF attributes defined for\nthe variable can be obtained with the C{ncattrs()} method. These\nattributes can be created by assigning to an attribute of the\nL{Variable} instance. A dictionary containing all the netCDF attribute\nname/value pairs is provided by the C{__dict__} attribute of a\nL{Variable} instance.\n\nThe instance variables C{dimensions, dtype, ndim, shape}\nand C{least_significant_digit} are read-only (and\nshould not be modified by the user).\n\n@ivar dimensions: A tuple containing the names of the dimensions\nassociated with this variable.\n\n@ivar dtype: A numpy dtype object describing the variable's data type.\n\n@ivar ndim: The number of variable dimensions.\n\n@ivar shape: a tuple describing the current size of all the variable's\ndimensions.\n\n@ivar scale:  if True, C{scale_factor} and C{add_offset} are automatically\napplied. Default is C{True}, can be reset using L{set_auto_scale} and\nL{set_auto_maskandscale} methods.\n\n@ivar mask:  if True, data is automatically converted to/from masked arrays\nwhen missing values or fill values are present. Default is C{True}, can be\nreset using L{set_auto_mask} and L{set_auto_maskandscale} methods.\n\n@ivar least_significant_digit: Describes the power of ten of the smallest\ndecimal place in the data the contains a reliable value.  Data is\ntruncated to this decimal place when it is assigned to the L{Variable}\ninstance. If C{None}, the data is not truncated. \n\n@ivar __orthogonal_indexing__: Always C{True}.  Indicates to client code\nthat the object supports \"orthogonal indexing\", which means that slices\nthat are 1d arrays or lists slice along each dimension independently.  This\nbehavior is similar to Fortran or Matlab, but different than numpy.", /*tp_doc*/
