+// 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);

+// 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";
