Howdy :)

I built a lab for my students at USF where, in 1hr 45minutes, they 
converted the Python grammar that comes with Python's distribution to 
ANTLR format:

This might help indirectly :)

For the record, the syntax of antlr is good, it's just that converting 
from an LR-based tool like yacc can cause trouble like left-recursion 
and such.
