--------------------
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 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.

This is a rough cross between distutils' StrictVersion and LooseVersion;
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", which 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
candidates, and therefore are not as new as a version string that does not
contain them, and "dev" is replaced with an '@' so that it sorts lower than
than any other pre-release tag.
