/**
 * Implements hook_libraries_info_alter().
 *
 * To get into this hook, add a new key to the library definition in
 * hook_libraries_info().
 *
 * Here's an example:
 *
 * 'cdn' => array(
 *   'aliases' => array('ol3', 'openlayers3'),
 *   'limit' => 3,
 *   'options' => array(
 *     'weight' => 0,
 *     'group' => $js_css_group,
 *   ),
 *   'download' => array(
 *     'versions' => array('3.8.1'),
 *     'plugins' => array(
 *       'cdnjs' => array('3.8.2')
 *       '*' => array('latest')
 *     ),
 *   ),
 *   'request' => array(
 *     'timeout' => 5,
 *   )
 * )
 *
 * - plugins: array, the list of cdn plugins to search the library from.
 *            It Will use all of them if not set.
 * - aliases: array, if the library has different names.
 * - limit: integer, set this to limit the number of results. If set to 3, it
 *          will return the 3 latest versions available.
 * - options: array, this array will be applied to each file definition,
 *            see drupal_add_TYPE() (js or css) to see which are the keys.
 * - download: array, options to download a local copy of the library
 *   - versions: array, version to download on any CDN when available.
 *   - plugins: array, keys are CDN plugin ids and the special keyword '*' can
 *              be use to specify all CDN plugins. Values are versions to
 *              download when available. The special keyword: 'latest' can be
 *              used to download the latest version available.
 * - request: array, this array will be the configuration that will be passed
 *            to the request function. See drupal_http_request() for a list of
 *            key values.
