9156// way to register. Lowercase jquery is used because AMD module names are
9157// derived from file names, and jQuery is normally delivered in a lowercase
9158// file name. Do this after creating the global so that if an AMD module wants
9159// to call noConflict to hide this version of jQuery, it will work.
9160
9161// Note that for maximum portability, libraries that are not jQuery should
9162// declare themselves as anonymous modules, and avoid setting a global if an
9163// AMD loader is present. jQuery is a special case. For more information, see
