        An Earley Algorithm Parser toolkit.
        ===========================================
        
        This package uses Jay Earley's algorithm for parsing context free
        grammars, and comes with some generic Abstract Syntax Tree
        routines. There is also a prototype scanner which does its job by
        combining Python regular expressions.
        
        (SPARK stands for Scanning, Parsing, and Rewriting Kit. It is a poor
        name since it conflicts with a more popular package of the same
        name. In the future we will rename this.)
        
        The original version of this was written by John Aycock for his Ph.d
        thesis and was described in his 1998 paper: "Compiling Little
        Languages in Python" at the 7th International Python Conference. The
        current incarnation of this code is maintained (or not) by Rocky
        Bernstein.
        
        Note: Earley algorithm parsers are almost linear when given an LR grammar.
        These are grammars which are left-recursive.
        
        Installation
        ------------
        
        This uses `setup.py`, so it follows the standard Python routine:
        
        ::
        
            python setup.py install # may need sudo
            # or if you have pyenv:
            python setup.py develop
        
        Example
        -------
        
        The github `example` directory_ has a worked-out examples; Package uncompyle6_
        uses this and contains a much larger example.
