XWindow library (Xlib) for basic functions and two additional
higher-level programming toolkits: the Xt Intrinsics toolkit and the
Osf Motif widget library set. Xlib is the lowest level of programming
interface in X and deal with the window drawing area. Xt is part of
the X standard which defines routines for building and using widgets.
