However, if you copy some (nontrivial) things from Sage source code (like examples coming from thematic tutorials or doctests), then you have to follow the GPL (the question being what means nontrivial).

Others are welcome to contribute more verbose assessments of this.
Personally, I think that any such interpretation (on the open-source or proprietary side) would be insane from a practical standpoint - does a Python script need to be GPLed? - but I'm sure there are many points of view.Tue, 02 Feb 2016 11:08:47 -0600http://ask.sagemath.org/question/32415/does-a-file-written-as-a-sage-script-need-to-be-gpled-since-sage-is-gpled/?answer=32419#post-id-32419
