Lowercase jquery is used because AMD module names are 10667 // derived from file names, and jQuery is normally delivered in a lowercase 10668 // file name. Do this after creating the global so that if an AMD module wants 10669 // to call noConflict to hide this version of jQuery, it will work. 10670 10671 // Note that for maximum portability, libraries that are not jQuery should 10672 // declare themselves as anonymous modules, and avoid setting a global if an 10673 // AMD loader is present. jQuery is a special case.
