[antlr-interest] Code munger & Simple grammar for code generation eclipse plugin Akrogen

[Miguel Ping]

If you're absolutely sure that you won't need a specialized grammar,
probably you can trim down an existing java grammar to suit your
needs. If you're familiar with antlr, it should be easy to do that.

As for adding grammars on the fly, you will always need to compile the
grammar. What you can do (with another generator :) is to compile the
grammar at runtime.
