== Concurrent Version System
CVS is a version control system.
Using it, you can record the history of your source files.
It originally used to be a front-end to the older [https://en.wikipedia.org/wiki/Revision_Control_System Revision Control System] when it was created.

=== Usage
To initialize your personal `CVSROOT`, you have to ask personnel to add you to the group `cvsadmin` before you can do anything. Afterwards, you can initialize repositories from your [wiki:Geidontei Geidontei] session.

If you intend to work locally and publish your changes on the server, those are the possible values for the `CVSROOT` environment variable

* pServer URI: `:pserver:USER@cvs.chaotic.ninja:/cvs/USER` (requires `cvs login`)
* SSH URI: `:ext:USER@cvs.chaotic.ninja:/cvs/USER` (requires `CVS_RSH` set to `ssh`)
