Include this jQuery plugin to restore the jQuery.browser API, removed in 1.9.0. Useful if you have dependencies that still require it, like the popular jQuery BBQ plugin.

  if ( matched.browser ) {
    browser[ matched.browser ] = true;
    browser.version = matched.version;
  }

  // Chrome is Webkit, but Webkit is also Safari.
  if ( browser.chrome ) {

  } else if ( browser.webkit ) {
