A while ago I made a package in order to generate nice theroem boxes for the redaction of some lecture notes I made for my school (voluntarily, as a student).
Today I realized that my school were using this package everywhere and without my permission.
I would like to license this package using Creative Commons (I'm very happy to let everyone use my package, but not without my permission, especcially for what they are doing with it).
T*he problem is that my package uses some other packages*, like xkeyval, ifthen or tikz. Most of them are under LPPL, and I don't know if I can license my work with my conditions knowing that it uses other pieces under specific licensing...
I hope that my question is clear : I'm not really fluent in English.
Thank you, Flyerjet
