    <para>BusyBox combines tiny versions of many common UNIX utilities into a single small
     executable. It provides replacements for most of the utilities you usually find in GNU
     fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than
     their full-featured GNU cousins; however, the options that are included provide the
     expected functionality and behave very much like their GNU counterparts. BusyBox provides
     a fairly complete environment for any small or embedded system.</para>
