Lowercase jquery is used because AMD module names are 10832// derived from file names, and jQuery is normally delivered in a lowercase 10833// file name. Do this after creating the global so that if an AMD module wants 10834// to call noConflict to hide this version of jQuery, it will work. 10835 10836// Note that for maximum portability, libraries that are not jQuery should 10837// declare themselves as anonymous modules, and avoid setting a global if an 10838// AMD loader is present. jQuery is a special case.
