 * It’s the simplest of errors. It sets up two callbacks as follows:
 *     ```
       add_action( 'admin_enqueue_scripts', 'enqueue_scripts' );
       add_action( 'admin_print_footer_scripts', 'add_pointer_scripts' );
       ```
   
 * But there are no such functions “enqueue_scripts” or “add_pointer_scripts”! The
   author meant to use methods of the class “phpinfo” as callbacks. There should
   be a “phpinfo::” prefix to the function names.
