 /// 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 alowed on the main thread.
+/// a blocking call, which is not allowed on the main thread.
