-		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.
