-/*
- * 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).

- * Collect variables across events.
- *
- * usage: collect [--add|--remove] <checkpoint> <id> <idlist>
- *
- * Adds ID <id> to the list governed by <checkpoint>.
- * <id> must be part of the ID list <idlist>.
- * If all IDs given by <idlist> are listed (ie collect has been
- * invoked for each ID in <idlist>) collect returns 0, the
- * number of missing IDs otherwise.
- * A negative number is returned on error.
