 * autoload and template manifest generation:
 *   - Only modules with _config.php files are scanned.
 *   - If a _manifest_exclude file is present inside a directory it is ignored.
 *   - Assets and module language directories are ignored.
 *   - Module tests directories are skipped if the ignore_tests option is not
 *     set to false.
