-/// @file
-/// This example demonstrates loading and running a very simple NaCl
-/// module.  To load the NaCl module, the browser first looks for the
-/// CreateModule() factory method (at the end of this file).  It calls
-/// CreateModule() once to load the module code from your .nexe.  After the
-/// .nexe code is loaded, CreateModule() is not called again.
-///
-/// Once the .nexe code is loaded, the browser then calls the
-/// LoadProgressModule::CreateInstance()
-/// method on the object returned by CreateModule().  It calls CreateInstance()
-/// each time it encounters an <embed> tag that references your NaCl module.

-/// module on the web page.  The browser will ask the Module object to create
-/// a new Instance for each occurrence of the <embed> tag that has these

-///     type="application/x-nacl"
