Sure Jim. I have found my way around Maven and now i am able to build the
tool.jar alone. I will use the current templates from the snapshot. I have
also found that ANTLR is specifically disabling the default parameter values
being assigned to the parameters passed to the rules. This functionality is
present in C++(as you may know). But is there a reason why we are doing
this?

Thanks,
Gokul.
