# verbatimfiles.perl
# Jens Lippmann <lippmann@rbg.informatik.tu-darmstadt.de> 6-FEB-96
#
# Extension to LaTeX2HTML to support verbatim.sty/verbatimfiles.sty.
#
# Change Log:
# ===========
# jcl = Jens Lippmann
#
# $Log: verbatimfiles.perl,v $
# Revision 1.6 1999/04/09 18:16:51 JCL
# changed my e-Mail address
#
# Revision 1.5 1998/12/02 01:22:53 RRM
# -- wrap the \verbatimfile and \verbatimlisting commands
#
# Revision 1.4 1998/03/22 20:52:50 latex2html
# reviewed for 98.1, works & is testable via devel/tests/regr/verbatim/run
#
# Revision 1.3 1998/02/19 22:24:34 latex2html
# th-darmstadt -> tu-darmstadt
#
# Revision 1.2 1996/12/23 01:36:50 JCL
# o added some informative comments and log history
# o uses now shell variable TEXINPUTS (set up before by LaTeX2HTML)
# to locate input files
# o verbatimlisting is now numbered according to the LaTeX output I
# got here: empty lines also numbered, but not the first if empty.
#
# Revision 1.1 1996/12/18 04:31:29 JCL
# was formerly verbatim.perl, now renamed to this file
#
# JCL -- 6-FEB-96 -- created
#
#
# Note:
# This module provides translation for the \verbatimfile and
# \verbatimlisting commands of the verbatimfiles.sty package.
#
# The naming of verbatim.sty is a bit blurred.
# Here are the versions which are available, together with their
# identification:
# o dbtex verbatim.sty by Rowley/Clark
# Provides:
# - \verbatimfile, \verbatimlisting
# It is also named verbatimfiles.sty, and supported by
# this Perl module.
#
# o verbatim.sty 1.4a (jtex), 1.4d (ogfuda), 1.4i (AMS LaTeX),
# 1.5i (LaTeX2e) by Sch"opf
# Provides:
# - verbatim environment, comment environment, \verbatiminput
# Supported by verbatim.perl.
#
# o FWEB verbatim.sty
# Provides:
# - verbatim environment, \verbfile, \listing, \sublisting
# Currently not supported by LaTeX2HTML.
