[antlr-interest] Need pointers for tools which convert ANTLR v2 to v3

[Sam Harwell]

Considering the effort it took to migrate the ANTLR core grammars from v2 to
v3 over the past week, I'm pretty sure such a tool doesn't exist.

In many ways the conversion isn't too difficult, but converting anything
involving AST generation or manipulation can be quite challenging.

Hi, I was using the tool mentioned at (
http://www.antlr.org/wiki/display/ANTLR3/Migrating+from+ANTLR+2+to+ANTLR+3
) for converting .g file from v2 to v3. However, the tool mentioned on it is
not reliable and stable. 
If anybody can provide pointers to a more robust conversion tool which
converts grammers from v2 to v3, that will be grateful.
