+ * @param $file
+ *   The full path to the file where the callback function is implemented.
+ * @param $arguments
+ *   Optional array of arguments to pass into the callback when it is invoked.
+ *   Note that the first argument to the callback is always the FileTransfer
+ *   object created by authorize.php when the user authorizes the operation.
+ * @param $page_title
+ *   Optional string to use as the page title once redirected to authorize.php.
+ * @return
+ *   Nothing. This function redirects to authorize.php and does not return.
