[antlr-interest] BNF to ANTLR

[Loring Craymer]

Actually, this is easier to do automatically.  Any BNF dialect takes about 2 pages for parser + lexer description of the BNF in ANTLR; it is very easy to write a translator from one BNF dialect to another (ANTLR).  You will still have to rework the resulting grammar.
