# This script is executed when the omegalib python interpreter (orun) starts, 
# before running application scripts.
# It sets up a system menu with several config options for sound, navigation, 
# graphics etc. If you want to change (or remove) the default menu, use the  
# orun/initScript config option to specify a new or an empty script.
# You can also change the orun/appStartFunction config option to change the 
# entry point into this script (by default it is set to _onAppStart)
