    longDescription = ''
      PLY is an implementation of lex and yacc parsing tools for Python.
      In a nutshell, PLY is nothing more than a straightforward lex/yacc
      implementation.  Here is a list of its essential features: It's
      implemented entirely in Python; It uses LR-parsing which is
      reasonably efficient and well suited for larger grammars; PLY
      provides most of the standard lex/yacc features including support for
      empty productions, precedence rules, error recovery, and support for
      ambiguous grammars; PLY is straightforward to use and provides very
      extensive error checking; PLY doesn't try to do anything more or less
      than provide the basic lex/yacc functionality.  In other words, it's
      not a large parsing framework or a component of some larger system.
