- * This file contains some functions which did not fit into one of the RedDAV
- * classes.
- *
- * The extended SabreDAV classes you will find in the RedDAV namespace under
- * @ref includes/RedDAV/.
- * The original SabreDAV classes you can find under @ref vendor/sabre/dav/.
- * We need to use SabreDAV 1.8.x for PHP5.3 compatibility. SabreDAV >= 2.0
- * requires PHP >= 5.4.
- *
- * @todo split up the classes into own files.
