Hi Mark, Thanks for your question. I’ve raised your licensing query with the FSF’s compliance contact at [email protected]<mailto:[email protected]> to get an authoritative answer on how the GPL applies. I’ll share their response as soon as I hear back. Best, David

Do not click links or open attachments unless you recognise the sender and know the content is safe. This looks exciting! From an open source license perspective - if I import this Python package into my commercial Python software, does that force me to open source my software? I’m confident I do not have to do that if I call gnubg as an external service.

I’d be very grateful for any feedback, bug reports, or suggestions to improve the extension, documentation, or packaging.
