Is BlueTrip still being actively developed?

I've been using BlueTrip for a while now in my site framework. I have just discovered html5boilerplate and am very impressed with it. I will be looking at trying to use BlueTrip with it (html5boilerplate has some very cool CSS but doesn't try and be a full css framework).

However, I am concerned that BlueTrip doesn't look like it's still being developed. There haven't been proper documentation, and I am not sure if things have been updated. With CSS3 starting to become more and more common (particularly helped by css3pie.com and modernizr) I think this important.

Don't get me wrong, I really like BlueTrip- it is simple but comprehensive too.

Any thoughts welcome!
