[antlr-interest] Debugging

[loic.lefevre at bnpparibas.com]

Hello all,
I wonder how to use the different class in the antlr.debug package.
Does anyone know what I can do with say  DebuggingCharScanner or
LLkDebuggingParser?
In brief I need to return better error messages than the well known
"unexpected null".

Regards,
Loïc
