class_docstr: Grammar subclass that reads classic pgen output files.
  
  The run() method reads the tables as produced by the pgen parser
  generator, typically contained in two C files, graminit.h and
  graminit.c.  The other methods are for internal use only.
  
  See the base class for more documentation.
docstr: Load the grammar tables from the text files written by pgen.
