A serie of questions related themselves.
Context: I'm writting a LaTeX document and I want to license it under a GPL v3 license. I have a own package with some macros, the great majority insignificants, but any of them can be useful to other users. One of these macros is a modified version of an answer: How to draw a series of paths in a TikZ chronology diagram?
- The official and third-parties LaTeX packages are licensed under LPPL. I guess my included packages are all LPPL licensed (I haven't search one by one its licenses) But, LPPL isn't compatible with GPL license. Can I use LaTeX packages in a GPL .tex document?, and why if are both mutually incompatibles?
- Is a creative commons license GPL-compatible?
- Can I use an (modify) answer (creative commons license) in a GPL document? Specially if a user specifies nothing in its user page about the license of his answers: Relicensing code from answers
I hope not to forget any important answer related to my situation.
