Antlr 4.0 License coverage of generated code and grammar files.

[mali5820k]

I couldn't really find an answer to this online but a Google groups discussion that said that Antlr's license only covers the parser generator, not the generated code and grammar files.

I just wanted to confirm if that really is the case as online posts can have conflicting or misinformed answers, and I want to know how to give credit to the use of Antlr in any of my projects the right way if the aforementioned post isn't correct.
