The Combinatorial Mathematica package contains all the programs from
the book, "Implementing Discrete Mathematics: Combinatorics and Graph
Theory with Mathematica" by Steven S. Skiena, Addison-Wesley Publishing
Co., Advanced Book Program, 350 Bridge Parkway, Redwood City CA 94065.
ISBN 0-201-50943-1.  For ordering information, call 1-800-447-2226.

Combinatorial Mathematica currently consists of one file, Combinatorica.m.
It is a 100K ASCII file, and so should be easy to ftp.  Since some mailers
choke on files this large, we have also prepared a distribution of three
smaller files, Part01, Part02, and Part03.

    ------------------------------------------------------------------

(0) A General Public License for Combinatorial Mathematica is in the file
    COPYING.

(1) To execute Combinatorial Mathematica, enter Mathematica and load the
    package (<<Combinatorica.m}

(2) Documentation strings for all important functions are included with
    the package.

(3) By sending your address to skiena@sbcs.sunysb.edu, you will be placed
    on a Combinatorial Mathematica mailing list and informed about
    new releases.

(4) Part01, Part02, and Part03 are shar files.  Running each through unshar
    or /bin/sh unpacks the files.  The main package is broken into three
    files: part1, part2, and part3.  To reconstruct the package, the three
    parts must be concatenated into the file Combinatorica.m.  The script
    makepackage does this automatically.

(5) A library of graphs appears in the directory graphs.  A much more
    interesting library appears in the directory graffiti

(6) The file, spremb.tar, contains the source to the spremb system,
    produced by students at the University of Queensland, Australia.
    The graph editor ged, which runs under both X-windows and SunTools,
    reads and writes files in a format similar to Combinatorica, so it
    provides a useful tool for working with the package.  There is a more
    recent and considerably smaller version of Xged in Xged5.0.tar.Z.
    We assume no responsibility for problems in porting spremb to your
    environment.

    For more information about spremb, contact Tony Gedge at 
    tonyg@batserver.cs.uq.oz.au or Peter Eades at eades@cs.newcastle.edu.au.

(7) The files VE041.Z and VE0.41.ReadMe contain a package by Komei Fukuda and
    Ichiro Mizukoshi of the University of Tsukuba, Tokyo, for enumerating all
    vertices of a convex polyhedra given by a system of linear inequalities,
    and all vertices (points) of an arrangement given similarly.  This
    package uses Combinatorica to display the graphs associated with the
    polytopes.  To decompress use the command 'uncompress VE041'
    on your home system.

    For more information, contact Komei Fukuda at
	fukuda@gssm.otsuka.tsukuba.ac.jp

(8) The files Unfold* contain a package by Makoto Namiki and Komei Fukuda
    containing Mathematica programs to unfold three-dimensional polytopes
    into the plane.  This is useful for making polyhedral models, and
    for trying to answer whether every convex polyhedra contains such
    an unfolding.  

    For more information, contact Komei Fukuda at
        fukuda@gssm.otsuka.tsukuba.ac.jp

(9) The directory graffiti contains 195 graphs collected by Siemion Fajtlowicz
    for his famous program graffiti.  These form a great database against
    which to test conjectures.
