 # UPGRADING Snappymail
 #
 # I've found this to be working fine when upgrading my Snappymail. The
 # commands should be used at your own risk. I take no responsibility.
 #
-# This example assumes that Snappymail is installed in the following
-# folder;
-#
-#     /var/www/snappy.somesite.com/ -- see $YOUR_SERVER_FOLDER
-#
-# Change the path to match your setup. 
+# The script can only be run from the  SnappyMail install directory!
