* How to Get and Install COMB

Comb comes as a self-extracting tar/csh script. This replaces the previous separate tar distribution. Get the file InstallComb2000.2 (anonymous ftp). Make it executable, then run it. The script will extract the source code from itself, compile, and install. You'll be asked a few questions along the way and a status report will be generated at the end indicating success or failure. If you have previously installed comb, the script will detect your old installation and save it before installing the new version.
