// 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. For more information, see |
