Posted this just now:

> A parser for ANTLR's metalanguage that builds an AST representing the 
> grammar.   Included is antlr.tree.g that walks the trees and 
> antlr.print.g that walks the trees and spits the grammar back out.  
> Note that it ignores everything except stuff relevant to rules and 
> possibly even ranges at the moment.
