Er, I think you will probably want to read what it says in the README:

*** THIS CODE IS NOT FINISHED ***

This doesn't implement anything like the same interface
that the previous version did. In fact a large amount of
the interface and API code remains unwritten because it's
been sitting on my hard disc for the last 6 months. I have
been persuaded to release unfinished code to the community
(yes, greg, you managed to persuade me). So here it is if
you want to play with it.
