Re: About Examples

[Jack Park <jack@resource-optimizer.com>]

Alberto's concerns struck me as important.  Andrew's response mirrors my
own behavior in this matter.  Reading the thesis over again make sense.
I built the minibasic, which does nearly everything I want, and learned a
lot from that.

However, some kind of tutorial on writing grammars for SableCC would be
useful.  My old copy of Aho & Ulhman just doesn't get it for me. Is there
anyone out there who could create such a document with examples?
