 :mod:`gzip` --- Support for :program:`gzip` files

 .. module:: gzip
    :synopsis: Interfaces for gzip compression and decompression using file objects.
 
+This module provides a simple interface to compress and decompress files just

+The data compression is provided by the :mod:``zlib`` module.
 
-The data compression provided by the ``zlib`` module is compatible with that
-used by the GNU compression program :program:`gzip`. Accordingly, the
