# The eventprocessing pattern in use: the complex event processing engine of a wind farm
# watches turbine T-07. An over-temperature alarm is the event object that records the
# actual overheating of the gearbox; the engine abstracts that alarm into a health
# warning and makes it a part of the shutdown incident it opens for the turbine.
