About Smacc

Let me try and re-ask this question. (Maybe this is Sebastien's
problem, maybe not). It's certainly mine ;-)
I've downloaded SmaCC from Squeakmap. I've gone through the
calculator tutorial (very nice) and generated a scanner and parser
(two classes, CalculatorScanner and CalulatorParser). There are also
nice examples StScanner and StParser. I can run them in the UI
tool. So far, so good.
I am completely at a loss to know how to use the Scanner and the
Parser from other code. I remember having the same problem with TGen
years ago, and eventually giving up. The generated code has no
obvious entry point ...
I tried STParser parseMethod: sourceString and got an immediate
walkback. The answer is probably obvious when you know, but it is
decidedly NON-obvious when you don't. Can someone help? Better
still, can someone put this information in the documentation.
