[antlr-interest] AntLR Grammar for structured text

[Bharath S]

Hi Terence,

I played around a bit with AntLR by adding my own
grammar and the syntax is cool so far. I'm dabbling
with a CC for the first time and hence the concern.

The Python grammar conversion is actually pretty
useful. Have you ever worked with Structured Text(a
PLC programming language)? I have the grammar for the
language and I need to translate it to AntLR format.

Thanks for your prompt reply!
