it's perfectly fine with me. so, in two weeks we freeze the development 
and fix bugs until october. i wanted to add a noise function the other 
day, but i can hold off starting that for a while.

do you have the unit tests checked in? maybe we could also test the 
scripts in the examples folder.

best,
