"""Distribution with support for 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.
'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.

For example, 'dist.exclude(py_modules=["x"])' would remove 'x' from
the distribution's 'py_modules' attribute. Excluding packages uses
the 'exclude_package()' method, so all of the package's contained
packages, modules, and extensions are also excluded.
Currently, this method only supports exclusion from attributes that are
lists or tuples. If you need to add support for excluding from other
attributes in this or a subclass, you can add an '_exclude_X' method,
where 'X' is the name of the attribute. The method will be called with
the value passed to 'exclude()'. So, 'dist.exclude(foo={"bar":"baz"})'
will try to call 'dist._exclude_foo({"bar":"baz"})', which can then
handle whatever special exclusion logic is needed.
