a-Linux
asmutils is a set of miscellaneous utilities written in assembly language, targeted on embedded systems and small distributions (e.g. installation or rescue disks); also it contains a small libc and a crypto library. It features the smallest possible size and memory requirements, the fastest speed, and offers fairly good functionality. Now project supports Linux and BSD family (FreeBSD, OpenBSD, NetBSD); Unixware, Solaris, and AtheOS support is in beta stage (also there’s no more supported BeOS port), and it is /theoretically/ possible to port it to any i386 OS.
Another goal of this package is to provide a *portable* framework, and to encourage assembly programmers to write for Linux/UNIX. Usually UNIX is associated with C, and no one wants to deal with assembly.. Browse the source, look — it is simple. Read the docs, start to write, and you will like it; assembly programming is a lot of fun, especially when you deal with a UNIX-like operating systems.
In addition, this package has some “special bonus” like small intros, games, and other various assembly snippets.
These utilities also may be useful for system administrators; there were several reports that they have rescued when libc crashed and it was not possible to use usual system utilities.
