I greatly appreciate that you've explicitly made clear the licensing
terms of your FSA package. I'll now work on integrating your package
with the Sage discrete maths library code, in order to better support
undergraduate discrete maths using Sage. You're more than welcome in
joining this effort. I'm CC'ing this email to the Sage development
mailing list to inform Sage developers about your decision to license
your FSA package under the terms of the LGPLv3 license. Once again,
thank you very much for producing a Python package that supports
finite state automaton.

any code that is
(L)GPLv3 licensed in Sage. We can include GPLv2+ code, i.e., "the
author grants the
user the right to use the code under GPLv2 or any later version of GPL".
So FSA won't be included in Sage this year unless it is licensed under
(L)GPLv2+.

Excellent! I'll play with PyFSA and attempt to integrate it with Sage.
