X Window Interface for Prolog. A package for Prologs

following the Quintus foreign function interface

(e.g. SICStus Prolog). XWIP provides a (low-level)

Xlib-style interface to X. The current version was

developed and tested on SICStus 0.7 and MIT X11 R5 under

SunOS 4.1.1. It should be adaptable to many other Unix

configurations. Version 0.6.
