+    Newlib is a C library intended for use on embedded systems. It is a 
+    conglomeration of several library parts, all under free software 
+    licenses that make them easily usable on embedded products. Newlib 
+    is only available in source form. It can be compiled for a wide 
+    array of processors, and will usually work on any architecture with
+    the addition of a few low-level routines.
