1. Get the files you need. 2. If you are on windoze (god forbid) you can start clicking away hoping that everything will work fine in the end (or otherwise). 3. Unix : rename the executables to 'grcarma' and 'carma', chmod 755, place in PATH, rehash if needed. ______________________________________ NB. Operating system compatibility (a) The GNU/Linux grcarma executable was built -if you believe it- on a redhat 7.3 machine. If you can find a GNU/Linux machine that this executable doesn't work I'd love to hear from you. (b) Our access to macosx boxes ranges from very limited to non-existent. We have seen this executable running without problems on a 10.6.8 machine, and this is all we can say. (c) Windows XP, 7, Vista and 8 may under certain (non-reproducible) circumstances create the false impression that everything works as expected.
