+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' -- 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.

+
+      '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.

+Pluggable Distributions of Python Software
+==========================================
+
+Distributions
+-------------
+
+A "Distribution" is a collection of files that represent a "Release" of a
+"Project" as of a particular point in time, denoted by a
+"Version"::
+
+    >>> import sys, pkg_resources
+    >>> from pkg_resources import Distribution
+    >>> Distribution(project_name="Foo", version="1.2")
+    Foo 1.2
+
+Distributions have a location, which can be a filename, URL, or really anything
+else you care to use::
+
+    >>> dist = Distribution(
+    ...     location="http://example.com/something",
+    ...     project_name="Bar", version="0.9"
+    ... )
+
+    >>> dist
+    Bar 0.9 (http://example.com/something)
+
+
+Distributions have various introspectable attributes::
+
+    >>> dist.location
+    'http://example.com/something'
+
+    >>> dist.project_name
+    'Bar'
+
+    >>> dist.version
+    '0.9'
+
+    >>> dist.py_version == sys.version[:3]
+    True
+
+    >>> print dist.platform
+    None
+
+Including various computed attributes::
+
+    >>> from pkg_resources import parse_version
+    >>> dist.parsed_version == parse_version(dist.version)
+    True
+
+    >>> dist.key    # case-insensitive form of the project name
+    'bar'
+
+Distributions are compared (and hashed) by version first::
+
+    >>> Distribution(version='1.0') == Distribution(version='1.0')
+    True
+    >>> Distribution(version='1.0') == Distribution(version='1.1')
+    False
+    >>> Distribution(version='1.0') <  Distribution(version='1.1')
+    True
+
+but also by project name (case-insensitive), platform, Python version,
+location, etc.::
+
+    >>> Distribution(project_name="Foo",version="1.0") == \
+    ... Distribution(project_name="Foo",version="1.0")
+    True
+
+    >>> Distribution(project_name="Foo",version="1.0") == \
+    ... Distribution(project_name="foo",version="1.0")
+    True
+
+    >>> Distribution(project_name="Foo",version="1.0") == \
+    ... Distribution(project_name="Foo",version="1.1")
+    False
+
+    >>> Distribution(project_name="Foo",py_version="2.3",version="1.0") == \
+    ... Distribution(project_name="Foo",py_version="2.4",version="1.0")
+    False
+
+    >>> Distribution(location="spam",version="1.0") == \
+    ... Distribution(location="spam",version="1.0")
+    True
+
+    >>> Distribution(location="spam",version="1.0") == \
+    ... Distribution(location="baz",version="1.0")
+    False
+
+
+
+Hash and compare distribution by prio/plat
+
+Get version from metadata
+provider capabilities
+egg_name()
+as_requirement()
+from_location, from_filename (w/path normalization)
+
+Releases may have zero or more "Requirements", which indicate
+what releases of another project the release requires in order to
+function.  A Requirement names the other project, expresses some criteria
+as to what releases of that project are acceptable, and lists any "Extras"
+that the requiring release may need from that project.  (An Extra is an
+optional feature of a Release, that can only be used if its additional
+Requirements are satisfied.)
+
+
+
+The Working Set
+---------------
+
+A collection of active distributions is called a Working Set.  Note that a
+Working Set can contain any importable distribution, not just pluggable ones.
+For example, the Python standard library is an importable distribution that
+will usually be part of the Working Set, even though it is not pluggable.
+Similarly, when you are doing development work on a project, the files you are
+editing are also a Distribution.  (And, with a little attention to the
+directory names used,  and including some additional metadata, such a
+"development distribution" can be made pluggable as well.)
+
+    >>> from pkg_resources import WorkingSet
+
+A working set's entries are the sys.path entries that correspond to the active
+distributions.  By default, the working set's entries are the items on
+``sys.path``::
+
+    >>> ws = WorkingSet()
+    >>> ws.entries == sys.path
+    True
+
+But you can also create an empty working set explicitly, and add distributions
+to it::
+
+    >>> ws = WorkingSet([])
+    >>> ws.add(dist)
+    >>> ws.entries
+    ['http://example.com/something']
+    >>> dist in ws
+    True
+    >>> Distribution('foo',version="") in ws
+    False
+
+And you can iterate over its distributions::
+
+    >>> list(ws)
+    [Bar 0.9 (http://example.com/something)]
+
+Adding the same distribution more than once is a no-op::
+
+    >>> ws.add(dist)
+    >>> list(ws)
+    [Bar 0.9 (http://example.com/something)]
+
+For that matter, adding multiple distributions for the same project also does
+nothing, because a working set can only hold one active distribution per
+project -- the first one added to it::
+
+    >>> ws.add(
+    ...     Distribution(
+    ...         'http://example.com/something', project_name="Bar",
+    ...         version="7.2"
+    ...     )
+    ... )
+    >>> list(ws)
+    [Bar 0.9 (http://example.com/something)]
+
+You can append a path entry to a working set using ``add_entry()``::
+
+    >>> ws.entries
+    ['http://example.com/something']
+    >>> ws.add_entry(pkg_resources.__file__)
+    >>> ws.entries
+    ['http://example.com/something', '...pkg_resources.py...']
+
+Multiple additions result in multiple entries, even if the entry is already in
+the working set (because ``sys.path`` can contain the same entry more than
+once)::
+
+    >>> ws.add_entry(pkg_resources.__file__)
+    >>> ws.entries
+    ['...example.com...', '...pkg_resources...', '...pkg_resources...']
+
+And you can specify the path entry a distribution was found under, using the
+optional second parameter to ``add()``::
+
+    >>> ws = WorkingSet([])
+    >>> ws.add(dist,"foo")
+    >>> ws.entries
+    ['foo']
+
+But even if a distribution is found under multiple path entries, it still only
+shows up once when iterating the working set:
+
+    >>> ws.add_entry(ws.entries[0])
+    >>> list(ws)
+    [Bar 0.9 (http://example.com/something)]
+
+You can ask a WorkingSet to ``find()`` a distribution matching a requirement::
+
+    >>> from pkg_resources import Requirement
+    >>> print ws.find(Requirement.parse("Foo==1.0"))    # no match, return None
+    None
+
+    >>> ws.find(Requirement.parse("Bar==0.9"))  # match, return distribution
+    Bar 0.9 (http://example.com/something)
+
+Note that asking for a conflicting version of a distribution already in a
+working set triggers a ``pkg_resources.VersionConflict`` error:
+
+    >>> ws.find(Requirement.parse("Bar==1.0")) # doctest: +NORMALIZE_WHITESPACE
+    Traceback (most recent call last):
+      ...
+    VersionConflict: (Bar 0.9 (http://example.com/something),
+                      Requirement.parse('Bar==1.0'))
+
+You can subscribe a callback function to receive notifications whenever a new
+distribution is added to a working set.  The callback is immediately invoked
+once for each existing distribution in the working set, and then is called
+again for new distributions added thereafter::
+
+    >>> def added(dist): print "Added", dist
+    >>> ws.subscribe(added)
+    Added Bar 0.9
+    >>> foo12 = Distribution(project_name="Foo", version="1.2", location="f12") 
+    >>> ws.add(foo12)
+    Added Foo 1.2
+
+Note, however, that only the first distribution added for a given project name
+will trigger a callback, even during the initial ``subscribe()`` callback::
+
+    >>> foo14 = Distribution(project_name="Foo", version="1.4", location="f14") 
+    >>> ws.add(foo14)   # no callback, because Foo 1.2 is already active
+
+    >>> ws = WorkingSet([])
+    >>> ws.add(foo12)
+    >>> ws.add(foo14)
+    >>> ws.subscribe(added)
+    Added Foo 1.2
+    
+And adding a callback more than once has no effect, either::
+
+    >>> ws.subscribe(added)     # no callbacks
+
+    # and no double-callbacks on subsequent additions, either
+    >>> just_a_test = Distribution(project_name="JustATest", version="0.99")
+    >>> ws.add(just_a_test)
+    Added JustATest 0.99
+
+
+Finding Plugins
+---------------
+
+``WorkingSet`` objects can be used to figure out what plugins in an
+``Environment`` can be loaded without any resolution errors::
+
+    >>> from pkg_resources import Environment
+
+    >>> plugins = Environment([])   # normally, a list of plugin directories
+    >>> plugins.add(foo12)
+    >>> plugins.add(foo14)
+    >>> plugins.add(just_a_test)
+    
+In the simplest case, we just get the newest version of each distribution in
+the plugin environment::
+
+    >>> ws = WorkingSet([])
+    >>> ws.find_plugins(plugins)
+    ([JustATest 0.99, Foo 1.4 (f14)], {})
+
+But if there's a problem with a version conflict or missing requirements, the
+method falls back to older versions, and the error info dict will contain an
+exception instance for each unloadable plugin::
+
+    >>> ws.add(foo12)   # this will conflict with Foo 1.4
+    >>> ws.find_plugins(plugins)
+    ([JustATest 0.99, Foo 1.2 (f12)], {Foo 1.4 (f14): VersionConflict(...)})
+
+But if you disallow fallbacks, the failed plugin will be skipped instead of
+trying older versions::
+
+    >>> ws.find_plugins(plugins, fallback=False)
+    ([JustATest 0.99], {Foo 1.4 (f14): VersionConflict(...)})
+
+
+
+Platform Compatibility Rules
+----------------------------
+
+On the Mac, there are potential compatibility issues for modules compiled
+on newer versions of Mac OS X than what the user is running. Additionally,
+Mac OS X will soon have two platforms to contend with: Intel and PowerPC.
+
+Basic equality works as on other platforms::
+
+    >>> from pkg_resources import compatible_platforms as cp
+    >>> reqd = 'macosx-10.4-ppc'
+    >>> cp(reqd, reqd)
+    True
+    >>> cp("win32", reqd)
+    False
+
+Distributions made on other machine types are not compatible::
+
+    >>> cp("macosx-10.4-i386", reqd)
+    False
+
+Distributions made on earlier versions of the OS are compatible, as
+long as they are from the same top-level version. The patchlevel version
+number does not matter::
+
+    >>> cp("macosx-10.4-ppc", reqd)
+    True
+    >>> cp("macosx-10.3-ppc", reqd)
+    True
+    >>> cp("macosx-10.5-ppc", reqd)
+    False
+    >>> cp("macosx-9.5-ppc", reqd)
+    False
+
+Backwards compatibility for packages made via earlier versions of 
+setuptools is provided as well::
+
+    >>> cp("darwin-8.2.0-Power_Macintosh", reqd)
+    True
+    >>> cp("darwin-7.2.0-Power_Macintosh", reqd)
+    True
+    >>> cp("darwin-8.2.0-Power_Macintosh", "macosx-10.3-ppc")
+    False
