gui license ?

[jschueller]

the gui part uses PyQt, and the license text does not reflect the GPL our users were tricked into believing they can redistribute derived works of fmpy into BSD seems you need a dual license BSD/GPL for this

[t-sommer]

According to https://www.pythonguis.com/faq/pyqt-vs-pyside/ you need a commercial PyQt license if you bundle it with your software and you don't want to ship the source code.

yes, that or use GPL, but in any case it cannot be BSD
