# This function is for addon development only. It is called on addon reload. The addons system will replace
# setlistener() and maketimer() to track this resources automatically for you.
#
# Listeners created with setlistener() will be removed automatically for you. Timers created with maketimer() will have
# their stop() method called automatically for you. You should NOT use settimer anymore, see wiki at
# https://wiki.flightgear.org/Nasal_library#maketimer()
#
# Other resources should be freed by adding the corresponding code here, e.g. `myCanvas.del();`.
