You'll have history, rollback, tags, and much more with a real revision control system. RCS is not at all hard to learn with basic checkin (ci) checkout (co) and diff (rcsdiff) commands. Any time you spend learning RCS will help if you later have to move to CVS for a distributed solution. -- Regards, Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
