   4 One or more mappings from MIME types to the Native Client module
   5 that handles each type.
   6 For example, the bold code in the following snippet
   7 registers a Native Client module as the content handler
   8 for the OpenOffice spreadsheet MIME type.

  12 {
  13   "name": "Native Client OpenOffice Spreadsheet Viewer",
  14   "version": "0.1",
  15   "description": "Open OpenOffice spreadsheets, right in your browser.",
  16   <b>"nacl_modules": [{
  17     "path": "OpenOfficeViewer.nmf",
  18     "mime_type": "application/vnd.oasis.opendocument.spreadsheet"
  19   }]</b>
  20 }

  22
  23 <p>
  24 The value of "path" is the location of a Native Client manifest
  25 (a <code>.nmf</code> file)
  26 within the extension directory.
  27 For more information on Native Client and <code>.nmf</code> files, see the
  28 <a href="http://code.google.com/chrome/nativeclient/docs/technical_overview.html">Native Client Technical Overview</a>.

  32 Each MIME type can be associated with only one <code>.nmf</code> file,
  33 but a single <code>.nmf</code> file might handle multiple MIME types.
  34 The following example shows an extension
  35 with two <code>.nmf</code> files
  36 that handle three MIME types.

  60 <strong>Note:</strong>
  61 You can use Native Client modules in extensions
  62 without specifying "nacl_modules".
  63 Use "nacl_modules" only if you want the browser
  64 to use your Native Client module
  65 to display a particular type of content.
