Cool :)

Docs are definitely on my TODO, but since we're currently in the release phase 
for Qt 4.3 my time is fairly limited. But once 4.3 is out (which shouldn't 
take too long :) I plan to finish the Mac and Windows ports of Qt to use the 
new Harfbuzz API (Harfbuzz actually works nicely on Windows already, but I've 
had some strange problems in our glue code with bitmap fonts... don't ask :) 
and then integrate that into our Qt mainline. Once it is there it will be 
part of the daily GPL snapshots of Qt, which will then make it much easier to 
test changes to Harfbuzz with Qt.

In the meantime it shouldn't be too hard to figure out how the API basically 
works if you look at tests/shaping/main.cpp. It would be nice to take that 
code as basis for a little separate standalone manual test application for 
Harbuzz that allows rendering a piece of text using Freetype after it's been 
shaped with Harfbuzz. That shouldn't be too hard and may be a nice start 
project :)
