thanks @cameralibre @Lars2i ! this is a temporary license, in order to finish the trauvaux , brainstorming, restitution and layout.
So, we can have a debate about Linus Torvalds & Richard Stallman, free culture & open source, publication under license & copyleft & copyright, open hardware etc. Then we'll have a drink togerther an diner with French wine of course.
I promise you the booklet will be released under open source license. Just be patient
