[antlr-interest] About GPL

In the following, be clear that I Am Not A Lawyer (IANAL) and that you
should get competent, professional legal advice.... This is just IMEBHO.

It's your grammar so you can do whatever you like with it.

Correct, it's an odd case of a combined, derivative, generated work.

Note that any libraries, etc. that are part of the antlr run-time is fully
and only controlled by Antlr's license.

Completely FALSE.  You can only assert a license that is allowed for by
(i.e., is "compatible with") the license of Antlr. But...

...since the current version of Antlr (as with PCCTS before it) has been
placed into the public domain, you can literally do whatever the hell you
want because there's literally no license on it.

Even when Antlr has a license (for v3.x and beyond), you can *always* put
whatever license you want upon your grammar.

The upcoming license will hopefully make it clear how it applies to the
case of the generated code and any run-time libraries, etc.

Go wild,
