qWdS)a�Yields ModuleInfo for all modules recursively
    on path, or, if path is None, all accessible modules.

    'path' should be either None or a list of paths to look for
    modules in.

    'prefix' is a string to output on the front of every module name
    on output.

    Note that this function must import all *packages* (NOT all
    modules!) on the given path, in order to access the __path__
    attribute to find submodules.

    'onerror' is a function which gets called with one argument (the
    name of the package which was being imported) if any exception
    occurs while trying to import a package.  If no onerror function is
    supplied, ImportErrors are caught and ignored, while all other
    exceptions are propagated, terminating the search.

    Examples:

    # list all modules python can access
    walk_packages()

    # list all submodules of ctypes
    walk_packages(ctypes.__path__, ctypes.__name__+'.')

PEP 302 Finder that wraps Python's "classic" import algorithm

    ImpImporter(dirname) produces a PEP 302 finder that searches that
    directory.  ImpImporter(None) produces a PEP 302 finder that searches
    the current sys.path, plus any modules that are frozen or built-in.

    Note that ImpImporter does not currently support being used by placement
    on sys.meta_path.

    If fullname contains a '.', the finders will be for the package

    If the named module is in a package, that package is imported as a side

qbWWdQRXqpW|S)	a�Extend a package's path.

    Intended use is to place the following code in a package's __init__.py:

        from pkgutil import extend_path
        __path__ = extend_path(__path__, __name__)

    This will add to the package's __path__ all subdirectories of
    directories on sys.path named after the package.  This is useful
    if one wants to distribute different parts of a single logical
    package as multiple directories.

    It also looks for *.pkg files beginning where * matches the name
    argument.  This feature is similar to *.pth files (see site.py),
    except that it doesn't special-case lines starting with 'import'.
    A *.pkg file is trusted at face value: apart from checking for
    duplicates, all entries found in a *.pkg file are added to the
    path, regardless of whether they are exist the filesystem.  (This
    is a feature.)

    If the input path is not a list (as is the case for frozen
    packages) it is returned unchanged.  The input path is not
    modified; an extended copy is returned.  Items are only appended
    to the copy at the end.

    It is assumed that sys.path is a sequence.  Items of sys.path that
    are not (unicode or 8-bit) strings referring to existing
    directories are ignored.  Unicode items of sys.path that cause
    errors when used as filenames may cause this function to raise an
    exception (in line with os.path.isdir() behavior).

S)afGet a resource from a package.

    This is a wrapper round the PEP 302 loader get_data API. The package
    argument should be the name of a package, in standard module format
    (foo.bar). The resource argument should be in the form of a relative
    filename, using '/' as the path separator. The parent directory name '..'
    is not allowed, and nor is a rooted name (starting with a '/').

    The function returns a binary string, which is the contents of the
    specified resource.

    For packages located in the filesystem, which have already been imported,
    this is the rough equivalent of

        d = os.path.dirname(sys.modules[package].__file__)
        data = open(os.path.join(d, resource), 'rb').read()

    If the package cannot be located or loaded, or it uses a PEP 302 loader
    which does not support get_data(), then None is returned.
