!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!! 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.
