# There is no point in enabling this if you disabled IRC
# Still has one bug - python-irc won't retrieve properly topic
# enabled - True/False
# status_file - file in sysfs that contains 1 or 0 defining the state of button
# open_value - which value in status_file respresents the switch being in "OPEN" position, 1 character
# status_file - file that contains value of the button, may end with newline (you probably want something in /sys fs)
# open_value - which value in status_file respresents the switch being in "OPEN" position
#
# Note: for use with Raspberry Pi, to read from GPIO in sysfs, you need to enable the PIN in input mode before starting
# this daemon, e.g. with GPIO 11 as an example (note that there are 2 numbering PIN schemes):
# #!/bin/bash
# export PIN=11
#
# if [ '!' -d /sys/class/gpio/gpio$PIN ]; then
# echo $PIN > /sys/class/gpio/export
# echo in > /sys/class/gpio/gpio$PIN/direction
# fi
