From the webpage:
Python library/tools for combining and using Regular Expressions in a maintainable way
This library also allows you to:
- Maintain a database of Regular Expressions
- Combine them together using Patterns
- Search, Parse and Output data matched by combined Regex using Python functions.
If you know Regular Expressions already, this library basically just gives you a way to combine them together and hook them up to some callback functions in Python.
This looks like a very useful tool.
