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> |
