XWIP
     
        X Window Interface for Prolog.  A package for {Prolog}s
        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.
