PLY (Python Lex-Yacc) – To Write a Parser in Python (github.com)

Thanks. That's very good to know. Wisent looks great, and here's a link: https://github.com/seehuhn/wisent. My goal right now is to add the ability to quickly write a simple DSL into my skill set. I intend to start with PLY since it seems to have a minimally lower barrier to entry. The rules live in the .py file without need for additional compilation.
