Could you post some references to books or web pages or good keywords
to reduce the space search on the web. All books that I know off which
speak about parser generators are at the level of LL(1) or simplified
LR(1) (LALR(1) or other way of reducing the LR tables) except T.J. Parr
book on PCCTS which describe more how to use PCCTS than its
"redefinition" of LL(k) and how to use it to build a parser generator.
Web pages I've found with my naive keyword approaches have not be of
more use; some buzzwords like OO where added but if they were more than
buzzwords, it was not clear for me.

Thanks,
