This is Debian GNU/Linux's prepackaged version of the 'xpdf' viewer written by Derek B. Noonburg. This package was original built by Dirk Eddelbuettel from the sources at ftp://ftp.x.org/contrib/applications/xpdf-0.6.tar.gz. The only changes made are the addition of the Debian package maintenance system and minor editing in the Makefile.config. The upstream author's email address is: derekn@foolabs.com Copyright: Xpdf is copyright 1996-1998 Derek B. Noonburg. Xpdf is licensed under the GNU General Public License (GPL), version 2. In my opinion, the GPL is a convoluted, confusing, ambiguous mess. But it's also pervasive, and I'm sick of arguing. And even if it is confusing, the basic idea is good. In order to cut down on the confusion a little bit, here are some informal clarifications: - I don't mind if you redistribute xpdf in source and/or binary form, as long as you include all of the documentation: README, man pages (or help files), and COPYING. (Note that the README file contains a pointer to a web page with the source code.) - Selling a CD-ROM that contains xpdf is fine with me, as long as it includes the documentation. I wouldn't mind receiving a sample copy, but it's not necessary. - If you make useful changes to xpdf, please make the source code available -- post it on a web site, email it to me, whatever. If you're interested in commercial licensing, please contact me: derekn@aimnet.com The full text of the GPL can be found in /usr/share/common-licenses/GPL.
