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.
