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