Does Sage's GPL license apply to Sage scripts? Are Sage scripts considered to be linking to Sage? I would like to write and distribute some educational Sage scripts and leave them in the public domain.

I am not a lawyer either, but i confirm that you can put the license of your choice to your own scripts, even if they use Sage. 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).

"I am not a lawyer," as they always say, but this has been discussed many times and the answer seems to always come out as "absolutely not necessary", just inasmuch as a MS Word document doesn't get Word's license attached to it. 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.
