Use of $Id$ Symbol

Every file checked into the CVS repository should have the $Id$ symbol inside a comment, near the top of the file. The $Id$ token is expanded by CVS into a useful header, identifying the revision of the file, date last changed, and name of last user to change the file.

For example, the $Id$ for this document is $Id: ContributorsGuide.xml,v 1.21 2003/09/02 16:38:14 hlship Exp $.
