Örks. Didn't read that.

There are some tools I liked very much when dealing with language
translation in the past, but they don't fit her. None of them generates
Pascal Code out of the box.

ANTLR3 was my favourite, generating tree walkers with little extra work
(iirc). But it generates Java code.

Beautiful. Would you mind disclosing the name of that fine tool? ;)
