From Newsgroup: comp.lang.python.announce

竜 TatSu is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python.

竜 TatSu can compile a grammar stored in a string into a tatsu.grammars.Grammar object that can be used to parse any given input,
much like the re module does with regular expressions, or it can generate a Python module that implements the parser.

竜 TatSu supports left-recursive rules in PEG grammars using the algorithm
by Laurent and Mens. The generated AST has the expected left associativity.

This release adds optimizations and solves obscure bugs and backwards-compatibility issues.
