# How this thing works:
#   ${START} must be only what is needed for start-stop-daemon, DO NOT
#   ADD ANY PARAMETERS HERE!  we might use it for --test, for example.
#   ${STOP} works just like ${START}, --signal is used with it.
#
#   ${PARAMS} are the parameters to give the daemon when really starting
#   it.
