Recursive-descent parser and scanner generator

This is an experimental programming language front-end generator. Its implementation is mainly based on ideas taken from Coco/R and ANTLR. It generates light-weight efficient scanners and recursive-descent parsers, using LL(*) and syntatic and semantic predicates for LL conflicts resolution.

The implementation is written as a prototype in PHP, and may generate front-ends in C and PHP.
