[antlr-interest] Code generation advice

[Eric]

Ok, I'm curious as to what you are trying to do. It sounds like something I
once tinkered with but since I did not understand your exact goal I could
be totally wrong.

The only part that I understood as part of the goal was "generation of Java
interfaces from EBNF-style grammars". Are you trying to generate Java
interfaces from a grammar for other languages or interface languages such
as C++, CORBA, etc.?
