CommonJS

``` javascript var $ = requireOne('jquery', 'zepto', 'cheerio'); // => jQuery, Zepto or Cheerio, depending on which one is available., _(*5)


### AMD

``` javascript
require(['require-one'], function(requireOne) {

  // Retrieve the first package that is available.
  var $ = requireOne('jquery', 'zepto', 'cheerio');
  // => jQuery, Zepto or Cheerio, depending on which one is available.

  // ...
});

Globals
