-/// @file
-/// This example demonstrates building a dynamic library which is loaded by the
-/// 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 CreateInstance()
-/// method on the object returned by CreateModule().  If the CreateInstance
-/// returns successfully, then Init function is called, which will load the
-/// shared object on a worker thread.  We use a worker because dlopen is
-/// a blocking call, which is not allowed on the main thread.
