ABOUT: yaska was an ancient vedic grammarian and also happens to be the eponym for this utility WHY: basically I have 6-7 grammars that are ALL dealing with natural language and it is basically a real bitch sometimes to figure out if I'm making the right changes as I don't have that much experience with pegs in general and antlr in specific -- I've racked up quite a few run-time warnings dealing with this since my tests convey such a wide-range of natural-language expressions this test-suite allows you to sit back and concentrate on the grammar w/out having to resort to antlworks knowing that whenever you make a change your tests are passing and are making progress
