# Sample Event Script written by Bob Perry
#
# Enters via the avr_evtd daemon with the following command options:
# 0 - Special event following double press of the 'red' reset button
# 1 - AVR device has requested a halt due to error
# 2 - Shutdown request from timed shutdown logic
# 3 - User has released the power button
# 4 - User has pressed the power button
# 5 - User has released the 'red' reset button
# 6 - User has pressed the reset button
# 7 - User has held the power button > 3 seconds
# 8 - User has held the reset button > 3 seconds
# 9 - Disk used beyond DISKCHECK%
# F - Fan failure event, fan stopped for > FANSTOP seconds
# E - User selected EM-Mode
# S - Five minute shutdown warning event
# D - Error message handler
