[antlr-interest] How to have consistently named lexer/parser in a package?

[John Woods]

I just came across the answer, which is painfully obvious now that I see 
it... Simply differentiate the grammar files by extension:

     Foobar.lg3 // lexer grammar file
     Foobar.g3  // parser grammar file

Sorry for the noob post.
