^ Subject: Important information on the new GRAPE 2.1
 The new GRAPE 2.1 gap share library package
         for computing with graphs

*Important Information*

This GAP 3.2 share library package is the latest version of GRAPE.

Old GRAPE users should note that it includes online documentation, new
functions, some new (optional) function parameters, and the nauty
version 1.7 system (and they should alter their .gaprc so that an old
version of GRAPE is not read, and insert RequirePackage("grape");

As well as being available from Aachen, GRAPE 2.1 is available via
anonymous ftp from galois.maths.qmw.ac.uk ( in the file
pub/grape/2.1/grape.tar.Z. Also available is the file
pub/grape/2.1/grapedoc.dvi.Z, the uncompressed version of which
includes a description of GRAPE, the installation instructions, and
documentation for GRAPE functions (when GRAPE is installed, all this
documentation is available online in the usual GAP way). The file
grapedoc.dvi is also part of the grape.tar archive, and you should read

Please email L.H.Soicher@qmw.ac.uk if you install GRAPE 2.1.

If you use GRAPE to solve a problem then also tell me about it,
and reference

L.H.Soicher, GRAPE: a system for computing with graphs and groups, in
Proc. 1991 DIMACS Workshop on Groups and Computation, DIMACS Series in
Discrete Mathematics and Theoretical Computer Science, to appear.

If you use the automorphism group and graph isomorphism testing
functions of GRAPE 2.1 then you are also using Brendan McKay's nauty 1.7
package, and should also reference

B.D.McKay, nauty users guide (version 1.5), Technical Report
TR-CS-90-02, Computer Science Department, Australian National
University, 1990.

I hope you find GRAPE useful. Please send comments on GRAPE, bug
reports, etc. to L.H.Soicher@qmw.ac.uk.
