    :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

+Examples of usage
+-----------------
+
+Example of how to read a compressed file::
+
+   import gzip
+   f = gzip.open('/home/joe/file.txt.gz', 'rb')
+   file_content = f.read()
+   f.close()
+
+Example of how to create a compressed GZIP file::
+
+   import gzip
+   content = "Lots of content here"
+   f = gzip.open('/home/joe/file.txt.gz', 'wb')
+   f.write(content)
+   f.close()
+
+Example of how to GZIP compress an existing file::
+
+   import gzip
+   f_in = open('/home/joe/file.txt', 'rb')
+   f_out = gzip.open('/home/joe/file.txt.gz', 'wb')
+   f_out.writelines(f_in)
+   f_out.close()
