+ * $wgForeignFileRepos[] = array(
+ *   'class'                  => 'ForeignAPIRepo',
+ *   'name'                   => 'shared',
+ *   'apibase'                => 'http://en.wikipedia.org/w/api.php',
+ *   'fetchDescription'       => true, // Optional
+ *   'descriptionCacheExpiry' => 3600,
+ * );
+ *
+ * @ingroup FileRepo
