I'm planing to release a LaTeX template to share my adjustments I've worked out for an universty course. My first thought was to release it under CreativeCommons (BY-NC-SA 3.0) but right now I'm not sure if this affects the content of the user he adds to the TeX file to compile his PDF file. 

I don't want to force the user to license his content under CC, just the changes he applies to the template. 

Does some kind of CC license fit my purpose or do I have to switch to another license?
