Description:

tslib is an abstraction layer for touchscreen panel events, as well as
a filter stack for the manipulation of those events. It was created by
Russell King, of arm.linux.org.uk. Examples of implemented filters
include jitter smoothing and the calibration transform.

tslib is generally used on embedded devices to provide a common user
space interface to touchscreen functionality. It is supported by
Kdrive (aka TinyX) and OPIE as well as being used on a number of
commercial Linux devices including the Nokia 770.
