<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>
