Adding ID keywords in an RCS file
An ID keyword is just a string of characters in your file that will be updated automatically by RCS to reflect the latest version number. It's not necessary to have ID keywords in your file, but it can help you keep different versions straight.
The easiest way to get the version number information into your
file is to include the string "
in your file. Whenever you check out a new version with the
co command, RCS will add version information
before the second "
Here are all the possible ID keywords:
Author$expands to the author's login name.
Date$expands to the date of the last checkin.
Revision$expands to the revision number.
Source$expands to the pathname of the file within the RCS directory.
RCSfile$is the same as
Source$, but without the pathname.
Header$includes the pathname, revision, date, and author.
