[antlr-interest] woot! Found a fortran grammar

[Mathew Yeates]

Hi
I found an antlr grammar for f77 at The Open Fortran Parser website 
(http://fortran-parser.sourceforge.net/index.html). After looking at 
their grammar I can see I could never figured this out in a finite 
amount of time.

Now I want to build a translator to take Fortran to Python/C#.
After reading a few things I'm guessing that I want produce an AST and 
the then walk it, emitting Python when appropriate. The AST they produce 
will be flat since they define no tokens so I'll need to add this.

Or do I want to use rewrite rules?

Any input/tips/pointers are grealy appreciated.
