  DOC CONTROL
When working on big or small projects, one of the vital tools required to manage code, is RCS.

A Revision Control system called RCS is used in conjunction with the Make System. There are two main reasons for using a revision control system. Firstly, it restricts write access to any particular file to one person at a time thus avoiding possible conflicts which may occur when more than one person tries to make simultaneous modifications. Secondly, it incrementally records all modifications made to each file so that earlier versions may be retrieved in case of errors being inadvertently introduced. This is vital when a software project becomes large and has multiple users contributing to it. The web page Simple RCS Usage describes the basics to get you quickly using RCS. For a more in-depth tutorial on RCS, you can follow links in the RCS Tutorial. Within CPUG a special version of RCS, a Hacked RCS is what you use by default. A RCS FAQ (frequently asked questions) page is also available. See also the man pages on rcs, ci and co
