# $Id: frames.perl,v 1.5 1998/02/19 22:24:28 latex2html Exp $
# frames.perl - Martin Wilck (martin@tropos.de) 22.5.96
#
#
# Extension to the LaTeX2HTML program by Nikos Drakos
#
# Enable LaTeX2HTML to build pages using frames
# (HTML extension for browsers that understand frames)
#
# Change Log:
# jcl = Jens Lippmann <lippmann@cdc.informatik.tu-darmstadt.de>
# mwk = Martin Wilck
# rrm = Ross Moore <ross@mpce.mq.edu.au>
#
# $Log: frames.perl,v $
# Revision 1.5 1998/02/19 22:24:28 latex2html
# th-darmstadt -> tu-darmstadt
#
# Revision 1.4 1997/07/11 11:28:56 RRM
# - replace (.*) patterns with something allowing \n s included
#
# Revision 1.3 1996/12/24 10:25:15 JCL
# typo
#
# Revision 1.2 1996/12/24 10:23:43 JCL
# changed &remove_markers in &replace_markers
#
# (v1.1) 20 June 1996 - rrm
# for compatibilty with segmented documents
#
# (v1.2) 4 July 1996 - rrm
# supporting easy color-changes and using backgrounds.
#
# (v1.0) 22.5.96 - mwk - created
# Different frames are used for the navigation panel buttons,
# the main text field and the footnotes (if any).
#
# The package redefines the following subroutines of LaTeX2HTML:
# - process_footnote
# - post_process
# - make_footnotes
# - make_file
# - make_head_and_body
#
# This file should be put in your LATEX2HTMLSTYLES directory.
#
# The package will be loaded if the following perl code:
###############################################################################
# if ($FRAMES) {
# foreach $dir (split(/:/,$LATEX2HTMLSTYLES)) {
# print $dir;
# if (-f ($_ = "$dir/frames.perl")) {
# print "Loading $_...\n";
# require ($_);
# };
# } ;
# };
###############################################################################
# is inserted into the latex2html script (uncommented, of course)
# (I insert it directly before the call to &driver)
# and $FRAMES is set to 1 in one of your configuration files.
