DESCRIPTION = "BusyBox combines tiny versions of many common UNIX utilities into a single \
small executable. It provides minimalist 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 POSIX environment for any small or embedded \
system."
