Basic idea looks sound. Might actually be _easier_ on OSX, since it's Unix-like and you should be able to depend on /bin/bash. The notation `dirname $0` should give you the path to the current script, from which everything else can be calculated. (Caveat: Never actually done this on a Mac, and only did cursory web searching to check that it wasn't a ridiculous idea.) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
