  <para>
   For tar-based archives, this method decompresses the entire archive.
  </para>
  <para>
   For Zip-based archives, this method fails with an exception.
   The <link linkend="ref.zlib">zlib</link> extension must be enabled to decompress
   an archive compressed with with gzip compression, and the
   <link linkend="ref.bzip2">bzip2</link> extension must be
   enabled in order to decompress an archive compressed with bzip2 compression.
  </para>
  <para>
   In addition, this method automatically renames the file extension of the archive,
   <literal>.tar</literal> by default.
   Alternatively, a file extension may be specified with the second
   parameter.

  <para>

       Use this parameter to specify another file extension.  Be aware
