- uClibc - a small libc implementation
- Erik Andersen <firstname.lastname@example.org>
-uClibc (aka µClibc/pronounced yew-see-lib-see) is size-optimized
-implementation of the standard C library. The primary use is
-for developing embedded Linux systems. It is much smaller then
-the GNU C Library (glibc), but nearly all applications supported
-by glibc also compile and work perfectly with uClibc. Porting
-applications from glibc to uClibc typically involves just
-recompiling the source code. uClibc even supports shared
-libraries and threading. It currently runs on standard Linux
-and MMU-less Linux (also known as µClinux) systems on the
-following processors: ARM, i386, h8300, m68k, mips, mipsel,
-PowerPC, SH, SPARC, and v850.
