The following is taken from "http://www.foolabs.com/xpdf/about.html":

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.
