# A sample long-running supervisor event listener which demonstrates
# how to accept event notifications from supervisor and how to respond
# properly.  This demonstration does *not* use the
# supervisor.childutils module, which wraps the specifics of
# communications in higher-level API functions.  If your listeners are
# implemented using Python, it is recommended that you use the
# childutils module API instead of modeling your scripts on the
# lower-level protocol example below.
