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