1 This contains man page groff source for the CVS revision control system. 2 CVS is a version control system which allows you to keep old versions of 3 files (usually source code), keep a log of who, when, and why changes 4 occurred, etc., like RCS or SCCS. Unlike the simpler systems, CVS does 5 not just operate on one file at a time or one directory at a time, but 6 operates on hierarchical collections of directories consisting of version 7 controlled files. CVS helps to manage releases and to control the 8 concurrent editing of source files among multiple authors. CVS allows 9 triggers to enable/log/control various operations and works well over a 10 wide area network (see man pages). 11
