README file for the `orb' GAP4 package To get the newest version of this GAP 4 package download one of the archive files orb-x.x.tar.gz orb-x.x.zoo orb-x.x.tar.bz2 orb-x.x.zip and unpack it using gunzip orb-x.x.tar.gz; tar xvf orb-x.x.tar respectively unzoo -x orb-x.x.zoo and so on. (Note that if you use a browser like `netscape' for downloading the archive file the `gunzip' step above may already be done by the browser, although the name of your file may still have the misleading `.gz' extension.) Do this preferably (but not necessarily) inside the `pkg' subdirectory of your GAP 4 installation. It creates a subdirectory called `orb'. This completes the installation of the package. Recompiling the documentation is possible by the command `gap makedoc.g' in the orb directory. But this should not be necessary. E-mail me if there are any questions, remarks, suggestions. Also, I would like to hear about applications of this package. Max Neunhoeffer, e-mail: max.neunhoeffer@math.rwth-aachen.de
