 .. module:: gzip
    :synopsis: Interfaces for gzip compression and decompression using file objects.
 
+This module provides a simple interface to compress and decompress files just
+like the GNU programs :program:`gzip` and :program:`gunzip` would.
 
-The data compression provided by the ``zlib`` module is compatible with that
-used by the GNU compression program :program:`gzip`. Accordingly, the
-:mod:`gzip` module provides the :class:`GzipFile` class to read and write
+The data compression is provided by the :mod:``zlib`` module.
+
+The :mod:`gzip` module provides the :class:`GzipFile` class which is modeled
+after Python's File Object. The :class:`GzipFile` class reads and writes
 :program:`gzip`\ -format files, automatically compressing or decompressing the
-data so it looks like an ordinary file object.  Note that additional file
-formats which can be decompressed by the :program:`gzip` and :program:`gunzip`
-programs, such  as those produced by :program:`compress` and :program:`pack`,
-are not supported by this module.
