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