Precedence Parsing
==================

  `(require 'precedence-parse)' or `(require 'parse)'

This package implements:

   * a Pratt style precedence parser;

   * a "tokenizer" which congeals tokens according to assigned classes
     of constituent characters;

   * procedures giving direct control of parser rulesets;

   * procedures for higher level specification of rulesets.
