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