Alternative to BusyBox: embutils

A similar set of tiny utilities for embedded systems. Version 0.18 (Oct. 2006): 75 common commands are implemented.
Can only be built statically with diet libc!
Compared to BusyBox: Much less momentum, user and developer base. Still misses key commands and features.
But can achieve smaller size than BusyBox on standalone executables.
