This is the Debian GNU/Linux prepackaged version of the GNU groff document formatting system. GNU groff was written by James Clark . This Debian package was previously maintained by Fabrizio Polacco . It is now maintained by Colin Watson . The original tarball came from : 48fa768dd6fdeb7968041dd5ae8e2b02 groff-1.20.1.tar.gz and was simply renamed to groff_1.20.1.orig.tar.gz. Some patches have been applied to groff outside the debian directory. The Debian diff also appends /usr/share/groff/tmac to the default macro path for compatibility with versions of groff earlier than 1.17 (patch by Colin Watson). ========================================================================= Copyright (C) 1989-2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc.

On Debian systems, this is available in /usr/share/common-licenses/GFDL-1.3 as part of the base-files package. However, Debian does not consider this free when the Front-Cover Texts or Back-Cover Texts options are used. groff is distributed with a LICENSES file containing the following text (excerpted): The groff program is a free software project. It is licensed under the GNU General Public License (GNU GPL), version 3 or later. The file COPYING in the top directory of the groff source package contains a copy of the GPL that was downloaded from the GNU web site http://www.gnu.org/copyleft/gpl.txt at 3 jan 2009. All files part of groff are licensed under this version of the GPL (or licenses which are compatible with the GPL). You are free to choose version 3 or any subsequent version of the GPL. I e-mailed the upstream maintainer to clarify the intent of this. Here is the relevant part of the reply: From: Werner LEMBERG To: cjwatson@debian.org Subject: Re: Clarifying the scope of groff/LICENSE Date: Thu, 18 Nov 2004 00:19:52 +0100 (CET) > Since "compatible with the GPL" means to all intents and purposes > "may be distributed under the terms of the GPL", can I correctly > assume that groff/LICENSE grants me permission to distribute > groff/doc/groff.texinfo and groff/doc/pic.ms under the terms of the > GPL?

I haven't found time to revert the FDL stuff back to GPL. It basically affects only Bernd Warken and me, and we have both agreed to return to GPL in case FDL makes problems. (Note that this e-mail predates the current wording in LICENSES.) It is therefore my understanding that the copyright holders of the groff documentation intend it to be distributable under the terms of the GPL version 3 or later. The reference above to the FDL text in /usr/share/common-licenses/ is for information only. ========================================================================= The following material is based on that in the groff LICENSES file, which itself is licensed as follows: Copyright 2003, 2006, 2007, 2009 Free Software Foundation, Inc.
