# Subject: i8k-keys
#
# Hello,
#
# I've got the i8k-utils from you and the work fine. I wrote a small
# shell-script for use the mute-button in a toggle way with the alsa-driver.
# I will attach this script to this mail.
#
# Jan Setzer
#
# Usage:
#
# i8kbuttons -u "setmixer.sh up" -d "setmixer.sh down" -m "setmixer.sh mute"
