The cvs repositories can now also be accessed anonymously by setting:
CVSROOT = :pserver:anonymous@theory.cm.utexas.edu:/Groups/cvs
or by logging in with the command
cvs -d :pserver:anonymous@theory.cm.utexas.edu:/Groups/cvs login
If this is working correctly the anonymous user must log in with the passwd anonymous, and they will have read-only access.
