uisp source code

The version of uisp distributed with the Arduino platform supports the ATmega168 (obviously!), but the official version on the uisp web site doesn't, which means that uisp has since been modified to support the ATmega168.

Where is the source code for the version of uisp distributed with the Arduino platform? (It is GNU software, so the source code should be somewhere!).

Thanks.

We haven't actually used uisp for a while (since the ATmega168 support didn't work too well), and I think I just grabbed a random patch from somewhere, but here's a zip of the source: http://www.arduino.cc/files/uisp-20050207-m168.zip
