[Ctk-developers] PythonQt: No Commercial Usage (was Re: Indiana License ?)

Thu Mar 10 10:29:08 EST 2011

Hi,

Good points
1) I should have been saying Apache 2 - it is "better" than BSD
because it addresses contributions and patents.
2) If the code is not part of the same git checkout, then I agree with
you in assuming that we're probably not falling under gnu's definition
of combined works.   So, I agree that we're probably ok.

Sorry for jumping in...was uncertain on what was hosted where.

Thanks,
Stephen
