There're a few PDL manual pages that bear copyright notices (see
below) that, to my understanding, limit the user's freedom to
distribute the derived works. Specifically, these notices
conflict DFSG [1] in that they either:
• disallow “modifications and derived works” (by the means of
format conversion) “to be distributed under the same terms as
the license of the original software” (DFSG #3; should we
assume that the license allows commercial distribution of the
unaltered documentation);
• restrict a “party from selling or giving away the software as
a component of an aggregate software distribution containing
programs from several different sources” (DFSG #1; should we
assume that the commercial distribution is denied altogether.)
I thus believe that the distribution terms of the manual pages
in question should either be changed or clarified, or the manual
pages should be removed from the Debian package.
