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.

rz Yn X| S)aZ Return this platform's maximum compatible version.
distutils.util.get_platform() normally reports the minimum version
of Mac OS X that would be required to *use* extensions produced by
distutils. But what we want when checking compatibility is to know the
version of Mac OS X that we are *running*. To allow usage of packages that
explicitly require a newer version of Mac OS X, we must also know the
current version of the OS.
If this condition occurs for any other platform with a version in its
platform strings, this function should be extended accordingly.

`requirements` must be a sequence of ``Requirement`` objects. `env`,
if supplied, should be an ``Environment`` instance. If
not supplied, it defaults to all distributions available within any
entry or distribution in the working set. `installer`, if supplied,
will be invoked with each requirement that cannot be met by an
already-installed distribution; it should return a ``Distribution`` or
``None``.
Unless `replace_conflicting=True`, raises a VersionConflict exception if
any requirements are found on the path that have the correct name but
the wrong version. Otherwise, if an `installer` is supplied it will be
invoked to obtain the correct version of the requirement and activate
it.
`extras` is a list of the extras to be used with these requirements.
This is important because extra requirements may look like `my_req;
extra = "my_extra"`, which would otherwise be interpreted as a purely
optional requirement. Instead, we want to be able to assert that these
requirements are truly required.

Example usage::
distributions, errors = working_set.find_plugins(
Environment(plugin_dirlist)
)
# add plugins+libs to sys.path
map(working_set.add, distributions)
# display errors
print('Could not load', errors)
The `plugin_env` should be an ``Environment`` instance that contains
only distributions that are in the project's "plugin directory" or
directories. The `full_env`, if supplied, should be an ``Environment``
contains all currently-available distributions. If `full_env` is not
supplied, one is created automatically from the ``WorkingSet`` this
method is called on, which will typically mean that every directory on
``sys.path`` will be scanned for distributions.
`installer` is a standard installer callback as used by the
``resolve()`` method. The `fallback` flag indicates whether we should
attempt to resolve older versions of a plugin if the newest version
cannot be resolved.
This method returns a 2-tuple: (`distributions`, `error_info`), where
`distributions` is a list of the distributions found in `plugin_env`
that were loadable, along with any other distributions that are needed
to resolve their dependencies. `error_info` is a dictionary mapping
unloadable plugin distributions to an exception instance describing the
error that occurred. Usually this will be a ``DistributionNotFound`` or
``VersionConflict`` instance.

Any distributions found on `search_path` are added to the environment.
`search_path` should be a sequence of ``sys.path`` items. If not
supplied, ``sys.path`` is used.
`platform` is an optional string specifying the name of the platform
that platform-specific distributions must be compatible with. If
unspecified, it defaults to the current platform. `python` is an
optional string naming the desired version of Python (e.g. ``'3.3'``);
it defaults to the current version.
You may explicitly set `platform` (and/or `python`) to ``None`` if you
wish to map *all* distributions, not just those compatible with the
running platform or Python version.

This calls the ``find(req)`` method of the `working_set` to see if a
suitable distribution is already active. (This may raise
``VersionConflict`` if an unsuitable version of the project is already
active in the specified `working_set`.) If a suitable distribution
isn't active, this method returns the newest distribution in the
environment that meets the ``Requirement`` in `req`. If no suitable
distribution is found, and `installer` is supplied, then the result of

obtain an extraction location, and only for names they intend to
extract, as it tracks the generated names for possible cleanup later.

If the default extraction path is overridden and set to an insecure

replace an extracted file with an unauthorized payload. Warn the user
if a known insecure location is used.

This is where Mac header rewrites should be done; other platforms don't
have anything special they should do.
Resource providers should call this method ONLY after successfully
extracting a compressed resource. They must NOT call it on resources
that are already in the filesystem.
`tempname` is the current (temporary) name of the file, and `filename`
is the name it will be renamed to by the caller after this routine
returns.

If you do not call this routine before any extractions take place, the
path defaults to the return value of ``get_default_cache()``. (Which
is based on the ``PYTHON_EGG_CACHE`` environment variable, with various
platform-specific fallbacks. See that routine's documentation for more
details.)
Resources are extracted to subdirectories of this path based upon
information given by the ``IResourceProvider``. You may set this to a
temporary directory, but then you must call ``cleanup_resources()`` to
delete the extracted files when done. There is no guarantee that
``cleanup_resources()`` will be able to remove all extracted files.
(Note: you may not change the extraction path for a given resource
manager once resources have been extracted, unless you first call
``cleanup_resources()``.)

Delete all extracted resource files and directories, returning a list
of the file and directory names that could not be successfully removed.
This function does not have any concurrency protection, so it should
generally only be called when the extraction path is a temporary
directory exclusive to a single process. This method is not
automatically called; you must call it explicitly or register it as an
``atexit`` function if you wish to ensure cleanup of a temporary
directory used for extractions.

FileFinder_namespace_handlers_namespace_packagesc C s | t | <d S)a Register `namespace_handler` to declare namespace packages
`importer_type` is the type or class of a PEP 302 "Importer" (sys.path item
handler), and `namespace_handler` is a callable like this::
def namespace_handler(importer, path_entry, moduleName, module):
# return a path_entry to use for child packages
Namespace handlers are only called if the importer object has already
agreed that it can handle the relevant path item, and they should only
return a subpath if the module __path__ does not already contain an
equivalent subpath. For an example namespace handler, see
``pkg_resources.file_ns_handler``.

Packages installed by distutils (e.g. numpy or scipy),
which uses an old safe_version, and so
their version numbers can get mangled when
converted to filenames (e.g., 1.11.0.dev0+2329eae to
1.11.0.dev0_2329eae). These distributions will not be
parsed properly
downstream by Distribution and safe_version, so
take an extra step and try to get the version number from
the metadata file itself instead of the filename.

Each ``section`` is a stripped version of the section header ("[section]")
and each ``content`` is a list of stripped lines excluding blank lines and
comment-only lines. If there are any such lines before the first section
header, they're returned in a first ``section`` of ``None``.
