XFree86 Project, Inc.
     
         A non-profit organisation that
        produces XFree86, a freely redistributable implementation of
        the {X Window System} that runs on {Unix} and Unix-like
        operating systems and {OS/2}.  The XFree86 Project has
        traditionally focused on {Intel x86} based {platforms} (hence
        the "86"), but the current release supports other platforms.
