Sure. Sometime around 2.6.24 I updated this script (originally by Micah
Dowty) to include more evdev #defines, work on 64-bit systems, and
decode some bitvectors into their C symbols.

This is a Python interface to the Linux input system's event device.
Events can be read from an open event file and decoded into spiffy
python objects. The Event objects can optionally be fed into a Device
object that represents the complete state of the device being monitored.
