# Simple legacy plug test harness.
# Legacy plugs have a big green button on the front,
# and usually come in kits with a handheld remote control.
#
# Note: This is a temporary piece of code, that will be thrown away
# once the device object interface is written.
#
# Please don't use this as the basis for an application,
# it is only designed to be used to test the lower level code.
