I don't have an "official" listing for the contents of this file but if was forced to make a guess I would say it's, ummm, source for the csh.
shells/csh.tar.gz (93/12/09)
csh for the 3b1. Not all things are supported because of limitations of the 3b1 (i.e. stopped jobs, notify, etc...). This is my default shell. Packaged by Kevin Colagio.
