+ <p>This example demonstrates sending messages from JavaScript to the Native

+ Client module, and from the Native Client module to JavaScript.</p>

+ <p>There are two ways to do this: asynchronously and sychronously.</p>

+ <p><code>postMessage()</code> sends a message from JavaScript to the module

+ asynchronously. This means that the response must be handled in a callback.

+ </p>

+ <p><code>postMessageAndAwaitResponse()</code> sends a message synchronously.

+ JavaScript execution is blocked while the module generates and sends back

+ a response. The response from the module is returned from the call to

+ <code>postMessageAndAwaitResponse()</code>, so no callback is necessary.

+ </p>

+ <p>Take a look at <code>example.js</code> to see the difference between these

+ two methods.</p>
