+!! letsencrypt.sh has been renamed to dehydrated !!
+!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+Due to trademark violation letsencrypt.sh had to be renamed and is know called dehydrated.
+
+To make a clean cut dehydrated doesn't use the old config locations /etc/letsencrypt.sh and
+/usr/local/etc/letsencrypt.sh anymore, also the script file has been renamed.
+
+If you were using the default WELLKNOWN location please also update your webserver to use /var/www/dehydrated.
+
+You are currently running (or reading) a temporary wrapper which handles the old config locations,
+you should update your setup to use /etc/dehydrated and the 'dehydrated' script file as soon as possible.
+
+Script execution will continue in 10 seconds.
