9153// files that may use define, but not via a proper concatenation script that
9154// understands anonymous AMD modules. A named AMD is safest and most robust
9155// way to register. Lowercase jquery is used because AMD module names are
9156// derived from file names, and jQuery is normally delivered in a lowercase
9157// file name. Do this after creating the global so that if an AMD module wants
9158// to call noConflict to hide this version of jQuery, it will work.
9159
9160// Note that for maximum portability, libraries that are not jQuery should
9161// declare themselves as anonymous modules, and avoid setting a global if an
9162// AMD loader is present. jQuery is a special case. For more information, see
