Summary: extracting last mod date with troff

In article <455@dione.rice.EDU>, William LeFebvre writes
	that he'd like to be able to print the mod date of an input file
	under tex, rather than just the date of printing.

we do this with troff.  all of our document source files are under rcs control.
you could also use sccs.  we define a macro RV that extracts the date info,
and then include a line
	.RV $Header$
in the file before checking it in.  rcs inserts the mod date in the header
line.  you might be able to come up with a similar scheme for tex.
