Keyword Substitution (RCS Keywords)
===================================

CVS can perform certain textual substitutions in files, allowing you to
keep some kinds of information automatically up to date in your files.
All of the substitutions are triggered by a certain keyword pattern,
surrounded by dollar signs.  For example,

     $Revision$

in a file expands to something like

     $Revision: 1.5 $

and CVS continues to keep the revision string up to date as new
revisions are committed.
