An interface between Prolog application program s and the X Window System that aims to be independent from the Prolog engine , provided that it has a Quintus foreign function interface (e.g. SICStus and YAP ). It is mostly written in Prolog and is divided in two libraries: Edipo - the lower level interface to the Xlib functions; and Ytoolkit - the higher level user interface toolkit.
