Searching the list of locations specified by path, yielding distributions whose names match name, if specified. If path is None, sys.path is searched. If name is None, all recognized distributions are yielded. Distribution objects yielded by this routine may be added to sys.metapath in order to make them accessible for importing, as they are PEP 302-compatible "importer" objects.
Open the named resource as a file-like object, using the specified mode ('t', 'b', or 'U'). (Note that this does not necessarily return an actual file; if you need a fileno() or an actual operating system file, you should use resource_filename() instead.)
resource_filename(package_name,resource_name)
Return a platform file or directory name for the named resource. If the package is in an egg distribution, the resource will be unpacked before the filename is returned. If the named resource is a directory, the entire directory's contents will be extracted before the directory name is returned. Also, if the named resource is an "eager" resource such as a Python extension or shared library, then all "eager" resources will be extracted before the resource's filename is returned. (This is to ensure that shared libraries that link to other included libraries will have their dependencies available before loading.)
set_extraction_path(path)
Set the base path where resources will be extracted to. If not set, this defaults to os.expanduser("~/.python-eggs"). Resources are extracted to subdirectories of this path, named for the corresponding .egg file. You may set this to a temporary directory, but then you must call cleanup_resources() to delete the extracted files when done. (Note: you may not change the extraction path for a given resource manager once resources have been extracted, unless you first call cleanup_resources().)
cleanup_resources(force=False)
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.
