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 [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

Any time you spend learning RCS will help if you later have to move to CVS for a distributed solution. Thanks to both for the solutions... The short-term fix by Jack is exactly what I was looking for... but for long term use I really like the potential that RCS has (was never aware that function existed). Will definately be spending some time with that and likely be moving to that in the future. Thanks again.
