-<h1>Native Client Module Ruby</h1>
-<p>
- <!-- Load the published .nexe. This includes the 'nacl' attribute which
- shows how to load multi-architecture modules. Each entry in the "nexes"
- object in the .nmf manifest file is a key-value pair: the key is the
- instruction set architecture ('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 'nacl' attribute to the
- _dbg.nmf version of the manifest file.
-
- Note: Since this NaCl module does not use any real-estate in the browser,
- it's width and height are set to 0.
-
- 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.
