  <!-- 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 runtime
  ('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.
