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.
