-r"""zipextimporter - an importer which can import extension modules
-from zipfiles without unpacking them to the file system.
-
-This file and _memimporter.pyd is part of the py2exe package.
-
-Overview
-========
-
-zipextimporter.py contains the ZipExtImporter class which allows to
-load Python binary extension modules contained in a zip.archive,
-without unpacking them to the file system.
-
-Call the zipextimporter.install() function to install the import hook,
-add a zip-file containing .pyd or .dll extension modules to sys.path,
-and import them.
-
-It uses the _memimporter extension which uses code from Joachim
-Bauch's MemoryModule library. This library emulates the win32 api
-function LoadLibrary.
-
-Sample usage
-============
-
-You have to prepare a zip-archive 'lib.zip' containing
-your Python's _socket.pyd for this example to work.
