Lowercase jquery is used because AMD module names are 10823// derived from file names, and jQuery is normally delivered in a lowercase 10824// file name. Do this after creating the global so that if an AMD module wants 10825// to call noConflict to hide this version of jQuery, it will work. 10826 10827// Note that for maximum portability, libraries that are not jQuery should 10828// declare themselves as anonymous modules, and avoid setting a global if an 10829// AMD loader is present. jQuery is a special case.
