+"""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.

+    if you give it versions that would work with StrictVersion, then it behaves
+    the same; otherwise it acts like a slightly-smarter LooseVersion. It is
+    *possible* to create pathological version coding schemes that will fool
+    this parser, but they should be very rare in practice.
+
+    The returned value will be a tuple of strings.  Numeric portions of the
+    version are padded to 8 digits so they will compare numerically, but
+    without relying on how numbers compare relative to strings.  Dots are
+    dropped, but dashes are retained.  Trailing zeros between alpha segments
+    or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
+    "2.4". Alphanumeric parts are lower-cased.
+
+    The algorithm assumes that strings like "-" and any alpha string that
+    alphabetically follows "final"  represents a "patch level".  So, "2.4-1"
+    is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
+    considered newer than "2.4-1", whic in turn is newer than "2.4".
+
+    Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
+    come before "final" alphabetically) are assumed to be pre-release versions,
+    so that the version "2.4" is considered newer than "2.4a1".
+
+    Finally, to handle miscellaneous cases, the strings "pre", "preview", and
+    "rc" are treated as if they were "c", i.e. as though they were release

+Metadata-Version: 1.0
+Name: setuptools
+Version: 0.7a1dev-r45519
+Summary: Download, build, install, upgrade, and uninstall Python packages -- easily!
+Home-page: http://peak.telecommunity.com/DevCenter/setuptools
+Author: Phillip J. Eby
+Author-email: peak@eby-sarna.com
+License: PSF or ZPL
+Description: ``setuptools`` is a collection of enhancements to the Python ``distutils``
+        (for Python 2.3.5 and up on most platforms; 64-bit platforms require a minimum
+        of Python 2.4) that allow you to more easily build and distribute Python
+        packages, especially ones that have dependencies on other packages.
+        
+        Packages built and distributed using ``setuptools`` look to the user like
+        ordinary Python packages based on the ``distutils``.  Your users don't need to
+        install or even know about setuptools in order to use them, and you don't
+        have to include the entire setuptools package in your distributions.  By
+        including just a single `bootstrap module`_ (an 8K .py file), your package will
+        automatically download and install ``setuptools`` if the user is building your
+        package from source and doesn't have a suitable version already installed.
+        
+        .. _bootstrap module: http://peak.telecommunity.com/dist/ez_setup.py
+        
+        Feature Highlights:
+        
+        * Automatically find/download/install/upgrade dependencies at build time using
+        the `EasyInstall tool <http://peak.telecommunity.com/DevCenter/EasyInstall>`_,
+        which supports downloading via HTTP, FTP, Subversion, and SourceForge, and
+        automatically scans web pages linked from PyPI to find download links.  (It's
+        the closest thing to CPAN currently available for Python.)
+        
+        * Create `Python Eggs <http://peak.telecommunity.com/DevCenter/PythonEggs>`_ -
+        a single-file importable distribution format
+        
+        * Include data files inside your package directories, where your code can
+        actually use them.  (Python 2.4 distutils also supports this feature, but
+        setuptools provides the feature for Python 2.3 packages also, and supports
+        accessing data files in zipped packages too.)
+        
+        * Automatically include all packages in your source tree, without listing them
+        individually in setup.py
+        
+        * Automatically include all relevant files in your source distributions,
+        without needing to create a ``MANIFEST.in`` file, and without having to force
+        regeneration of the ``MANIFEST`` file when your source tree changes.
+        
+        * Automatically generate wrapper scripts or Windows (console and GUI) .exe
+        files for any number of "main" functions in your project.  (Note: this is not
+        a py2exe replacement; the .exe files rely on the local Python installation.)
+        
+        * Transparent Pyrex support, so that your setup.py can list ``.pyx`` files and
+        still work even when the end-user doesn't have Pyrex installed (as long as
+        you include the Pyrex-generated C in your source distribution)
+        
+        * Command aliases - create project-specific, per-user, or site-wide shortcut
+        names for commonly used commands and options
+        
+        * PyPI upload support - upload your source distributions and eggs to PyPI
+        
+        * Deploy your project in "development mode", such that it's available on
+        ``sys.path``, yet can still be edited directly from its source checkout.
+        
+        * Easily extend the distutils with new commands or ``setup()`` arguments, and
+        distribute/reuse your extensions for multiple projects, without copying code.
+        
+        * Create extensible applications and frameworks that automatically discover
+        extensions, using simple "entry points" declared in a project's setup script.
+        
+        In addition to the PyPI downloads, the development version of ``setuptools``
+        is available from the `Python SVN sandbox`_, and in-development versions of the
+        `0.6 branch`_ are available as well.

+
+    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.

+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
