I keep my files under RCS, and I've found that the RCS version is a more reliable metric. The macro is trivial: .\" Extract version number from RCS Id string. .de Id Version \\f(CW\\$3\\fP .. You could easily modify that to provide the date (in the simplest form, $4 and $5) of something like Id: vinum.mm,v 4.20 2003/06/29 04:33:42 grog Exp grog $ And of course this should extend to other versioning systems.
