| + ('x86-32', 'x86-64', etc.); the value is a URL for the desired NaCl module. |
| + To load the debug versions of your .nexes, set the 'src' attribute to the |
| + _dbg.nmf version of the manifest file. |
| + |
| + Note: The <EMBED> element is wrapped inside a <DIV>, which has both a 'load' |
| + and a 'message' event listener attached. This wrapping method is used |
| + instead of attaching the event listeners directly to the <EMBED> element to |
| + ensure that the listeners are active before the NaCl module 'load' event |
| + fires. This also allows you to use PPB_Messaging.PostMessage() (in C) or |
| + pp::Instance.PostMessage() (in C++) from within the initialization code in |
| + your NaCl module. |
