This is Debian/GNU Linux's prepackaged version of the 'xpdf' viewer written
by Derek B. Noonburg. This package contains PDF decryption patches from
Leo Smiers, and was originally built by Hamish Moffatt based on
Dirk Eddelbuettel's xpdf package. The upstream source was obtained
from http://www.foolabs.com/xpdf/

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:
