/**
 * @fileoverview Bootstrap file that loads all of the WebDriver scripts in the
 * correct order. Once loaded, pages can use {@code goog.require} statements
 * from Google DocType to load additional files as needed.
 *
 * Example Usage:
 *
 * <html>
 *   <head>
 *     <script src="webdriver-bootstrap.js"></script>
 *     <script>
 *       goog.require('goog.debug.Logger');
 *     </script>
 *     <script>
 *       window.onload = function() {
 *         goog.debug.Logger.getLogger('').info(
 *             'The page has finished loading');
 *       };
 *     </script>
 *   </head>
 *   <body></body>
 * </html>
