[antlr-interest] start state not found exception - regd.

[ASHOK REDDY]

Hello,

I converted a pre-existing  antlr v2 Graphviz Dot grammar into v3 grammar
using the tool given at antlr.org. The conversion was quite successful
without any errors. But when I tried to load in antlr works, it won't
display syntax tree of the rules and gives "Cannot display rule xyz because
start state not found". Enclosed is the converted Dot Grammar file and the
original one. Thankx a lot for the help.

- Regards.
  Ashok.
