+// DISCUSSION:
+//
+// The three main classes of interest are
+//
+//  MachMessage:    a wrapper for a mach message of the following form
+//   mach_msg_header_t
+//   mach_msg_body_t
+//   optional descriptors
+//   optional extra message data
+//
+//  MachReceiveMessage and MachSendMessage subclass MachMessage
+//    and are used instead of MachMessage which is an abstract base class
+//
+//  ReceivePort:
+//    Represents a mach port for which we have receive rights
+//
+//  MachPortSender:
+//    Represents a mach port for which we have send rights
+//
+// Here's an example to receive a message on a server port:
+//
+//        // This creates our named server port
+//        ReceivePort receivePort("com.Google.MyService");
+//
+//        MachReceiveMessage message;
+//        kern_return_t result = receivePort.WaitForMessage(&message, 0);
+//
+//        if (result == KERN_SUCCESS && message.GetMessageID() == 57) {
+//          mach_port_t task = message.GetTranslatedPort(0);
+//          mach_port_t thread = message.GetTranslatedPort(1);
+//
+//          char *messageString = message.GetData();
+//
+//          printf("message string = %s\n", messageString);
+//        }
+//
+// Here is an example of using these classes to send a message to this port:
+//
+//    // send to already named port
+//    MachPortSender sender("com.Google.MyService");
+//    MachSendMessage message(57);      // our message ID is 57
+//
+//    // add some ports to be translated for us
+//    message.AddDescriptor(mach_task_self());     // our task
+//    message.AddDescriptor(mach_thread_self());   // this thread
+//
+//    char messageString[] = "Hello server!\n";
+//    message.SetData(messageString, strlen(messageString)+1);
+//
+//    kern_return_t result = sender.SendMessage(message, 1000); // timeout 1000ms
