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.
