tpb - program to use the IBM ThinkPad (tm) special keys

All the information used in this program was gathered by observing the device
/dev/nvram while pressing the buttons. This was done with the command
'watch -n 1 "cat /dev/nvram | xxd"'

This program was developed on a Thinkpad T21 (2647-4AG). I don't know if it
works on other models.

Use it at your own risk!!!

Installation:

- enable nvram in your kernel (section character devices), either as module
  or compiled into the kernel
- if you use nvram as module, load it
- make sure that the device /dev/nvram exists, else create ist with
  'mknod /dev/nvram c 10 144'
- install tpb with 'make && make install'
- run it with something like
  'tpb --verbose --thinkpad="/usr/bin/X11/xterm -T mutt -geometry 140x40 -e /usr/bin/mutt"'
