This contains the sgmlspl script which +is used to grok this file. Use it like this: + +nsgmls some-docbook-document.sgml | sgmlspl sgmlspl-specs/docbook2man-spec.pl + +=head1 OPTIONS + +=over 4 + +=item --section <label> + +Use the specified manpage section number, +if not specified in <MANVOLNUM>. Default is one (1). + +=item --date <string> + +Use the specified date in the .TH header. +Default is today. + +=item --lowercase | --preserve-case + +Convert output file names and cross-references to lower case. +Default is to convert to upper case. + +=head1 DESCRIPTION + +This is a sgmlspl spec file that produces Unix-style +manpages from RefEntry markup. + +See the accompanying RefEntry man page for 'plain new' documentation. :) + +=head1 LIMITATIONS + +Trying docbook2man on non-DocBook or non-conformant SGML results in +undefined behavior. :-) + +This program is a slow, dodgy Perl script. + +This program does not come close to supporting all the possible markup +in DocBook, and will produce wrong output in some cases with supported +markup. + +=head1 TODO + +Add new element handling and fix existing handling. Be robust. +Produce cleanest, readable man output as possible (unlike some +other converters). Follow Linux man(7) convention. +If this results in added logic in this script, +that's okay. The code should still be reasonably organized. + +Make it faster. If Perl sucks port it to another language. + +=head1 COPYRIGHT + +Copyright (C) 1998-1999 Steve Cheng <steve@ggi-project.org> + +Copyright (C) 1999 Thomas Lockhart <lockhart@alumni.caltech.edu> + +This program is free software; you can redistribute it and/or modify it +under the terms of the GNU General Public License as published by the Free +Software Foundation; either version 2, or (at your option) any later +version. + +You should have received a copy of the GNU General Public License along with +this program; see the file COPYING.
