+uClibc pronounced yew-see-lib-see is a C library for developing embedded Linux 
+systems. It is much smaller than the GNU C Library, but nearly all applications supported 
+by glibc also 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 (also known as uClinux) 
+systems with support for alpha, ARM, cris, i386, i960, h8300, m68k, mips/mipsel, PowerPC, 
+SH, SPARC, and v850 processors.
