+ * eGroupWare API loader
+ *
+ * Rewritten by RalfBecker@outdoor-training.de to store the eGW enviroment
+ * (egw-object and egw_info-array) in a php-session and restore it from
+ * there instead of creating it completly new on each page-request.
+ * The enviroment gets now created by the egw-class
