Ciro Santilli v3 LaTeX source code: github.com/OperaMagistris/Opera_Magistris_English_v3
Very unfortunate license "public domain license" with a "non religious" clause, whatever the fuck that is, which completely defeats the point of a public domain declaration:
The source code and text is under Public License and therefore can be used, translated and distributed at free will.It is only banned to use the text and content for religious propaganda.
