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 fileutils, shellutils, findutils,
textutils, grep, gzip, tar, etc. BusyBox provides a fairly complete
POSIX environment for any small or embedded system. 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 has been written with size-optimization and limited resources
in mind. It is also extremely modular so you can easily include or
exclude commands (or features) at compile time. This makes it easy to
customize your embedded systems. To create a working system, just add
a kernel, a shell (such as ash), and an editor (such as elvis-tiny or
ae).
