# This module is used to manipulate android sensors
# The sensor support is implemented in android_app module, so the user can enable the type of sensor he wants to use.
# There is an example of how you can use the android sensors in nit/examples/mnit_ballz :
-# `var app = new MyApp
+#
+# ~~~~
+# var app = new MyApp
# app.sensors_support_enabled = true
# app.accelerometer.enabled = true
# app.accelerometer.eventrate = 10000
# app.gyroscope.enabled = true
# app.light.enabled = true
# app.proximity.enabled = true
-# app.main_loop`
+# app.main_loop
+# ~~~~
#
# In this example, we enable the sensor support, then enable all types of sensors supported, before running the app.
# The result is you get all type of SensorEvent (ASensorAccelerometer, ASensorMagneticField ...) in the input method of your app
