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.

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'.

Wd S( s� Verify that feature makes sense in context of distribution
This method is called by the distribution just before it parses its
command line. It checks to ensure that the 'remove' attribute, if any,
contains only valid package/module names that are present in the base
distribution when 'setup()' is called. You may override it in a
subclass to perform any other required validation of the feature
against a target distribution.
