Why do you not consider to give people opportunities to use ZDF as regular libarary AS WELL, not only using lzt.
I mean much more useful and familiar way is:
- clone ZDF repo using git (or add as git submodule) or install using luarocks
- Write "require 'luazdf.math'" in you project (for that you should extend your lib)
I think it's better to give users BOTH ways and they will decide which one is better: copying without dependencies or add dependency without copying.
I like this project by the way and may contribute in case you agree with my suggestions =)
