I have installed the CVS repo (thanks, Mike): developers who already have cl.net logins can now checkout with
$ export CVS_RSH=ssh $ cvs -z3 -d :ext:<username>@common-lisp.net:/project/mcclim/cvsroot co mcclim
Anoncvs will automatically follow when the cron job kicks in (may even be there now) - see http://common-lisp.net/faq.shtml
Please shout if any problems (but I'm away next week, so don't shout to me alone if you want a timely resolution)
