/**
* Native input transport.
*
- * Uses anonymous shared memory as a whiteboard for sending input events from an
- * InputPublisher to an InputConsumer and ensuring appropriate synchronization.
- * One interesting feature is that published events can be updated in place as long as they
- * have not yet been consumed.
+ * The InputChannel provides a mechanism for exchanging InputMessage structures across processes.
*
- * The InputPublisher and InputConsumer only take care of transferring event data
- * over an InputChannel and sending synchronization signals. The InputDispatcher and InputQueue
- * build on these abstractions to add multiplexing and queueing.
+ * The InputPublisher and InputConsumer each handle one end-point of an input channel.
+ * The InputPublisher is used by the input dispatcher to send events to the application.
+ * The InputConsumer is used by the application to receive events from the input dispatcher.
