-/*
- * accelerometer - exports device orientation through property
- *
- * When an "change" event is received on an accelerometer,
- * open its device node, and from the value, as well as the previous
- * value of the property, calculate the device's new orientation,
- * and export it as ID_INPUT_ACCELEROMETER_ORIENTATION.
- *
- * Possible values are:
- * undefined
- * * normal
- * * bottom-up
- * * left-up
- * * right-up
- *
- * The property will be persistent across sessions, and the new
- * orientations can be deducted from the previous one (it allows
- * for a threshold for switching between opposite ends of the
- * orientation).
