1gdiffmk is approximately a recreation of the original Bell Labs/AT&T diffmk 2command for troff/nroff documents, with enhancements. 3 4It should not be confused with `diffmk' commands that operate on XML. 5 6The inspiration for this code was a Perl 2 version written in 1989 by Randal 7L. Schwartz. See 8 landfield.com/software/comp.sources.misc/archive-name/volume06/diffmk.p.gz 9 10The command also attempts to reproduce some of the functionality of the old 11`nrchbar' command. See 12 open-systems.ufl.edu/mirrors/ftp.isc.org/usenet/comp.sources.unix/volume10/nrchbar.Z 13 14Thanks to Werner Lemberg for help in making the package more portable and 15fit into the GNU groff source structure. 16 17Gnu diff(1) with the -Dname option does all of the work and sed(1) 18translates the output into something groff/troff/nroff can handle. 19 20Note the BUGS on the man page. 21 22The `tests' directory contains simple tests. `runtests run' runs them and 23compares the output against baseline files. Calling `runtests' without 24argument gives the usage. 25 26---------------------------------------------------------------------------- 27 28Copyright (C) 2004, 2005 Free Software Foundation, Inc. 29Written by Mike Bianchi <MBianchi@Foveal.com <mailto:MBianchi@Foveal.com>> 30 31This file is part of the gdiffmk utility, which is part of groff. 32 33groff is free software; you can redistribute it and/or modify it 34under the terms of the GNU General Public License as published by 35the Free Software Foundation; either version 2, or (at your option) 36any later version. 37 38groff is distributed in the hope that it will be useful, but WITHOUT 39ANY WARRANTY; without even the implied warranty of MERCHANTABILITY 40or FITNESS FOR A PARTICULAR PURPOSE.
