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 /dev, a shell, and a kernel. For
-a really minimal system, you can even use the busybox shell (not Bourne
-compatible, but very small and quite usable) and the busybox vi editor.

BusyBox was originally written to support the Debian Rescue/Install disks, but
it also makes an excellent environment for any small or embedded system.
Busybox in general will build on any architecture supported by gcc. It has
a few specialized features added for __sparc__ and __alpha__. insmod
functionality is currently limited to x86, ARM, SH3/4, powerpc, m68k,
- and MIPS.

Supported libcs:
- glibc-2.0.x, glibc-2.1.x, Linux-libc5, uClibc. People are looking at
- newlib and diet-libc, but consider them unsupported, untested, or worse.

scripting (such as an initrd that calls insmod a few times) since it does
not understand Bourne shell grammer. It does handle pipes, redirects, and

hush is also quite small (just 18k) and it has very complete Bourne shell

like for/do/done or case/esac and such. It also currently has a problem

msh: The minix shell (adds just 30k) is quite complete and handles things
like for/do/done, case/esac and all the things you expect a Bourne shell to

shell was also recently added, and several people (mainly Vladimir and Erik)
have been working on it. There are a number of configurable things at the
