Ok. I'll make a patch for it if no one else does ... maybe in a few days.

just to clarify,

Shahrokh Yadegari, IRCAM, and the JMax developers, ALL agreed with the switch to LGPL license.

so AFAIK, the 'GPL' claim in the source code is still there simply because no-one has changed it.

Well, it seems like all the authors agree and there's already an LGPL license. I only brought up all of this due to the inconsistency between whats actually there in the source files. I'd love for that to just be changed and we all move on. It's not like this is a huge patent / money maker thing. If being anal and bringing this to light truly means I *can't* use it in the long run, well than I should have done what most everyone else does in these situations: use it and keep my mouth shut :P.

We know what is allowed / not allowed by Apple, don't need a lawyer for that.

One (not so minor) note on this... "expr" is copyright IRCAM (hahrokh Yadegari
was working for IRCAM at the time) and is also included in Max, so it
might be sbject to agreements between IRCAM and Cycling '74.

I was under the impression it was under GPL, not LGPL.  I just looked and
saw that, indeed, the LICENSE.txt file says LGPL and the expr source code
print out "GPL" on startup.  The reason I think it's actually GPL is that
that is how IRCAM released it -- as part of jMAX, years ago.  The current
code is based on that original code.  Although it was extensively reworked
by Shahrokh, I presume the GPL terms under which he was working required him
to release the result under GPL too.

So for the moment at least, I'm afraid FUD rules.

My vote would be to keep all the original GPL licenses in Pd vanilla's
expr, and to remove the LGPL readme.  GPL was the licensed under
which expr was originally released, so we can reasonably assume all the
copyright holders agreed to that license.

If the consensus was that it should be changed in order to accomodate
Pure Data builds on IOS, then everyone who wants to use expr on IOS
should pool their resources and hire a lawyer to explain what is and
isn't allowed under the LGPL and Apple's TOS.  The lawyer should also
find out if it was indeed possible to change the license to LGPL in light
of what Miller brings up about the original licensing.

That's two unknowns wrt LGPL expr, and they won't be solved by
revising the source nor IANAL discussions.
