    <para>The Xz package contains programs for compressing and decompressing
    files. It provides capabilities for the lzma and the newer xz compression
    formats.  Compressing text files with <command>xz</command> yields a better
    compression percentage than with the traditional <command>gzip</command> or
    <command>bzip2</command> commands.</para>
