@jtalir, @tdivis @tpazderka, any thoughts?

[tdivis]

"should" is not "must", IMHO it's awful to add something into each source file, I think it's fine to have licence in the project.

[tpazderka]

COPYRIGHT file is OK IMHO.

License should also be specified in setup.py.

I am against including the information in every file.
