# Instructions
# everything except step 2) as root here
# (unless you want to master udev...)

# 1) Install https://pythonhosted.org/evdev/install.html
# $ easy_install evdev
# (or if you're like me, easy_install --prefix=/opt/python-evdev with
# PYTHONPATH set as needed)

# 2) use xinput to disable any keyboards, mice or pedals that are for buzing,
# not for using with X

# 3) figure out which ev numbers from /dev/input/event? you want to work with
# by using cat

# 4) call this program with the device node
