Hi Fred,

Yep it's confusing but amazing!

An artwork or a piece of text in CC BY-SA can be safetely used inside a GNU GPL 
program and shared as a whole GNU GPL program (relicensed as GNU GPL). The 
reverse it's not possible.

This is very common in fully-free videogames (e.g. 0ad, SuperTuxKart, ...) 
released just under GNU GPL.

https://www.gnu.org/licenses/license-list.en.html#ccby

https://www.gnu.org/licenses/license-list.en.html#ccbysa (4.0)

We just have to ignore all the other Creative Commons licenses that are 
absolutely non-free. Like ND, NC and combinations of them.

Thank you again for your work in LibreJS!
