touchscreen calibration

From: Tias 

There is now a generic touchscreen calibration utility that can 
calibrate evtouch, as well as evdev (the now preferred upstream driver 
for touchscreens) and others.

I've uploaded it to mentors and mailed:
http://lists.debian.org/debian-mentors/2010/08/msg00066.html

You can download a binary deb package on the website:
