+ <!-- 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. |
+ |
+ The src points to a manifest file, which provides the Native Client plug-in |
+ a mapping between architecture and NaCl Executable (NEXE). |
+ |
+ We use a non-zero sized embed to give Chrome space to place the bad plug-in |
+ graphic, if there is a problem. |
