tslib is a library and utilities for reading touchscreen events and smoothing them out.
You need a touchscreen display.

Desktop linux usually does not come with tslib, rather it is used on touchscreen devices such as
Sharp Zaurus and Nokia n810.

You can download the source for it here
http://tslib.berlios.de/

The tslib plugin in Qt will act like a mouse, so once you get tslib and the plugin working, you wont
usually have to do much more.

It might already come with your cross toolchain for your touchscreen device.
