It is useful to quickly create a5parser from a grammar file in Python's grammar notation.  But I don't6want my parsers to be written in C (yet), so I'm translating the7parsing tables to Python data structures and writing a Python parse8engine.9Note that the token numbers are constants determined by the standard10Python tokenizer.  The standard token module defines these numbers and11their names (the names are not used much).  The token numbers are12hardcoded into the Python tokenizer and into pgen.  A Python13implementation of the Python tokenizer is also available, in the14standard tokenize module.15On the other hand, symbol numbers (representing the grammar's16non-terminals) are assigned by pgen based on the actual grammar17input.18Note: this module is pretty much obsolete; the pgen module generates19equivalent grammar tables directly from the Grammar.txt input file20without having to invoke the Python pgen C program.21"""22# Python imports23import re24# Local imports25from pgen2 import grammar, token26class Converter(grammar.Grammar):27    """Grammar subclass that reads classic pgen output files.28    The run() method reads the tables as produced by the pgen parser29    generator, typically contained in two C files, graminit.h and30    graminit.c.
