# verbatim.perl
# Jens Lippmann <lippmann@rbg.informatik.tu-darmstadt.de> 17-DEC-96
#
# Extension to LaTeX2HTML to support the verbatim.sty LaTeX2e package.
#
# Change Log:
# ===========
# jcl = Jens Lippmann
#
# $Log: verbatim.perl,v $
# Revision 1.10 2001/11/29 21:44:13 RRM
# -- update to use &replace_all_html_special_chars if defined
#
# Revision 1.9 1999/10/15 09:17:16 RRM
# -- enable link to stylesheet "verbatim" class
#
# Revision 1.8 1999/09/14 22:02:02 MRO
#
# -- numerous cleanups, no new features
#
# Revision 1.7 1999/04/09 18:15:17 JCL
# changed my e-Mail address
#
# Revision 1.6 1998/12/02 01:25:19 RRM
# -- preserve styles around the use of \verbatiminput
# -- wrap the \verbatiminput command; i.e. treat as an environment
#
# Revision 1.5 1998/03/22 20:52:49 latex2html
# reviewed for 98.1, works & is testable via devel/tests/regr/verbatim/run
#
# Revision 1.4 1998/02/19 22:24:33 latex2html
# th-darmstadt -> tu-darmstadt
#
# Revision 1.3 1996/12/23 01:33:58 JCL
# uses now shell variable TEXINPUTS (this is set up by LaTeX2HTML before)
# to locate the input file
#
# Revision 1.2 1996/12/18 04:30:32 JCL
# was formerly verbatimfiles.perl, however, its face changed
# quite much
#
#
# Note:
# This module provides translation for the \verbatiminput command of
# the verbatim.sty package.
# The comment/verbatim environments are handled by LaTeX2HTML itself.
#
# 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
# verbatimfiles.perl.
#
# 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 this Perl module.
#
# o FWEB verbatim.sty
# Provides:
# - verbatim environment, \verbfile, \listing, \sublisting
# Currently not supported by LaTeX2HTML.
