Keyword substitution
********************

   As long as you edit source files inside a working directory you can
always find out the state of your files via `cvs status' and `cvs log'.
But as soon as you export the files from your development environment
it becomes harder to identify which revisions they are.

   CVS can use a mechanism known as "keyword substitution" (or "keyword
expansion") to help identifying the files.  Embedded strings of the form
`$KEYWORD$' and `$KEYWORD:...$' in a file are replaced with strings of
the form `$KEYWORD:VALUE$' whenever you obtain a new revision of the
file.
