Acronym for Concurrent Versioncontrol System.

A way of allowing multiple people work on one set of files at the same time and have changes merged in and history and versions kept (much like the wiki).

CVS started off as a couple of shell script wrappers around RCS and diff3(1), and it's evolved into something much much more.

It's starting to show its age now however as it's starting to have a few design limitations.

cvs is invoked by using the cvs(1) command.

Someone wanna write some documentation about how to use cvs?

there are 3 commands you need to understand to use cvs:

1. cvs checkout
2. cvs update
3. cvs commit
