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