/**
 * Trigger hook to let the plugins register external drivers
 * as supported exporters.
 *
 * @return  array  $drivers  The array holding the drivers to load.
 */
public function onFetchSupportedExportDrivers($drivers)
{
    // create base path to "drivers" folder contained within the plugin
    $base = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'drivers' . DIRECTORY_SEPARATOR;

    // load all PHP files from "drivers" folder
    return glob($base . '*.php');
