This is mostly off topic, but related to LaTeX.
I have a template which contains about 40 files in different folders. And additionally some packages (.sty files) which shall be published soon.
The packages contain the typical copyright statement and LaTeX Project Public License lines.
Are these also necessary in the .tex files which contain the docs or can I create a licence.txt file for the whole folder?
For the template I also wonder if I can put everything under a license with a single file. Putting 10-30 lines of license statement in each file is something I want to avoid.
