# This script turns the off power to the layout after
|
|
# a specified time has passed with no activity. ('Activity'
|
|
# means a change in state of a sensor used as a block
|
|
# occupancy detector.) It's a sort of idle timeout for
|
|
# track power. It is intended to be run from the startup
|
|
# menu.
|

#
|

# The timeout is set at the top, in minutes.
