Wait a second-- didn't you decide not to include some external that Yves authored
which had a clause that made it nonfree? If so, then why are you arguing from the
practicality angle for another software package?
But those two questions are for curiosity's sake-- they are irrelevant to the discussion
at hand because all the licenses we're talking about are free software licenses. It's
simply a matter of whether one ought to say GPLv3 as a whole or that the core of
Pd-extended is GPL3, and that there are various free licenses for the external libraries.
(Well, there's also the issue of GPLv2 or later vs GPLv2 only, but we've completed
the discussion for that one.)
