   For tar-based archives, this method throws a
   <classname>BadMethodCallException</classname>, as compression of individual
   files within a tar archive is not supported by the file format.  Use
   <function>PharData::compress</function> to compress an entire tar-based archive.
  </para>
  <para>
   For Zip-based archives, this method decompresses all files in the
   archive.
   The <link linkend="ref.zlib">zlib</link>  or <link linkend="ref.bzip2">bzip2</link>
   extensions must be enabled to take advantage of this feature if any files
   are compressed using bzip2/zlib compression.
