# Author: Jody Klymak <jklymak@apl.washington.edu>, publisted by a posting
# to the pdftex mailinglist.
# recursively finds all your eps files. Looks down \input{fname}.
# CAVEATS:
# 1) cannot handle \input{fname} split over more than one line.
# 1.5) cannot handle multiple \input{} or \includegraphics{} on one line.
# 2) Must be run from same directory as the Latex file.
# 3) Does not look down $TEXINPUTS or anything fancy like that...
# 4) Handling of \include is untested (though I guess its trivial)
# 5) Assumes *all* your graphics inclusions are [e]ps. But don't
# fret, because if they are not epstopdf dies anyhow....
# 6) Does not distinguish between percent (\%) and comment (%).
# Changelog:
# 20030103 -- Lachlan Andrew <lha@users.sourceforge.net>
# * Only append '.tex' if $fname doesn't exist.
# * Correctly handle lines with '}' after the \includegraphics{}
# * Allow multiple extensions for graphics files. .eps -> .ps -> none
# (Should try them in the same order as \includegraphics does
# -- given by \DeclareGraphicsExtensions{}?)
# * Allow \include the same way as \input
# * Allow \includegraphics{} to be split over multiple lines
# * Check that commands begin with '\', and allow spaces before arguments
# EDIT these two lines for your system....
