I don't understand why ANTLRWorks can't deal with the grammars being
in separate files and support debugging without using the remote
option. I doubt this is something it couldn't do. I suspect it's just
something that Jean Bovet hasn't gotten around to implementing.

That makes sense. If you ever decide to create an Ant build script,
I'd be glad to help by sharing mine.
