What's GNU?

  What is GNU?  GNU's Not Unix!

  GNU is a project to develop a software system which everybody is
free to use, to study, to share, and to modify.  A considerable amount
of software has already been written specifically for the GNU project
(an editor and compiler were among the first, and hundreds of utilities,
games, and libraries have been added).  Some programs written by other
groups (such as the X Window System and the TeX typesetter) can be used
alongside the GNU software, and the GNU tools are often run on the Linux
kernel, forming the GNU/Linux system.

  An overview of the GNU Project is available online at:

  More relevant to this newsgroup is the GNU Backgammon program (gnubg for
short).  gnubg is free software being developed for the GNU Project, which
plays and analyses backgammon games and matches.  It has not yet been
released, although pre-releases are being made available to anybody who
would like to help us test what has been completed so far.  You can learn
more about gnubg from the page:

  While the primary target for GNU software is the GNU system itself,
many programs have been ported to other platforms; I understand that
the available pre-releases of gnubg run under GNU/Linux, *BSD, IRIX,
MS-DOS and MS Windows, Solaris, and Tru64 Unix operating systems, on
68K, 80x86, Alpha, ARM, IA-64, MIPS, PA-RISC, PowerPC, S/390 and SPARC
processors.  Ports to other systems are in the works.  If you would
like to compile a pre-release of gnubg yourself, the source code is
available from:

or via CVS (see the gnubg home page for directions to the CVS repository).

  The GNU Project does not generally make binaries of its software
available online (though you will be able to buy GNU CD-ROMs containing
gnubg once it is released).  However, independent groups often make
binaries of GNU software available; the locations of gnubg binaries I
am aware of are:

for Debian GNU/Linux, and

for MS Windows.  I have heard some discussion about putting gnubg in
the FreeBSD ports tree, but I don't know if it's there yet.

  If you do test a gnubg pre-release, please send any bug reports to
