+SEPERATING WORK BY GROUPS
+-------------------------
+If you are working with different groups on one cdist-configuration,
+you can delegate to other manifests and have the groups edit only
+their manifests. You can use the following snippet in
+**conf/manifests/init**:
+
+--------------------------------------------------------------------------------
+# Include other groups
+sh -e "$__manifest/systems"
+
+sh -e "$__manifest/cbrg"
