I've made some progress with the Amol's code that was uploaded to 
antlr.org.  It's at the point where it generates correct code for 
calc.g but not java.g.  I've also converted the ANTLR runtime classes 
into Python so the generated code runs with standard Python (i.e., 
doesn't require Jython).  One of the main remaining issues is getting 
non-trivial "case" statements converted to Python, which only provides 
"if-elif-else".

I'd be happy to upload what I've got to antlr.org or create a 
Sourceforge project so that other folks can get involved -- I haven''t 
had much time to spend on it lately.  Let me know what you think would 
work best for this kind of project.

Michael.
