+Deletion of Calendar folders
+
+When deleting a calendar folder a Kolab client must first delete all
+appointments on the server and then immediately call the pfb script
+
+	https://servername/freebusy/trigger/X/PATH/FOLDERNAME.pfb
+
+After calling the pfb script the Kolab client may immediately delete the emtpy
+folder. 
+
+On the other hand the server side pfb creation script MUST be able to
+handle empty or unexisting calendar folders. A trigger call to an unexisting 
+or empty folder leads to deletion of any traces related to this folder in the pfb storage.
+
 Future
 ------
 
 For the future scheme could eventually be extend towards:
-
-	- make it possible for clients to upload the pfb instead
-	of just triggering the creation. 
-	Advantages: Put load on the client.
 
 	- add referal type files for the cache hierachy that
 	make the collector script search for an pfb elsewhere.
