#!/bin/csh -f

# Usage: oldpdf fileroot ...

# Fileroot is the given file name or the part preceding ".tex".  So
# you get the same behavior from "oldpdf foo" or "oldpdf foo.tex".

# This command creates fileroot.pdf from fileroot.tex by using the
# initial 8 characters of the filename as a date to substitute for 
# \today usages in the .tex file.  Also modifies date of the .pdf
# file to match that of the .tex file or the date from the filename?


# TO BE CODED.  BELOW IS JUNK FROM ANOTHER COMMAND.
