Ok. We had this problem also a few weeks ago with this sparse stuff from
Youssef Saad. Luckily Andi Adler as already done some sparse stuff
which looks really nice and SHOULD be integrated into octave core.

I think, maybe I am wrong, but  the original authors are not aware of 
what kind of problems they are causing with their "private" Copyrights.
It looks that they want that this stuff IS USED and FREELY AVAILABLE 
for everybody. 
Limiting for non-commercial usage they probably aim at making no
binary-distributions for US-$ 1[0]*000.--.  (this should be a regexp
I think they are not aware of the fact that the GPL does not 
forbid commercial usage (selling $ 30,- CD's that is less than a
to toast that shit including machine costs) BUT will implicitly
make it of no economic interest because you have to give the source with
and you have to allow everybody to redistribute it without other
then putting it under GPL again (maye something else, please correct

Long sentences, short sense:

We have to convince these guys to put their software under GPL.

So who does that?
