YABT is a context sensitive string manipulation tool written in pure python. The project has the following goals:

* Provide implementations of string manipulation for specific tasks to be used inside applications. The current implementation is a context matching rule system combined with a finite state machine and a table for translating text into British Braille. This implementation should be useful for other tasks such as preparing text for a speech synthesiser by providing different tables.
* To provide a framework which developers can use to create new translation algorithms which can be used by any application using YABT. This side of YABT could do with further development and so is most likely going t see some changes as YABT matures.
