+Note: As of version 1.16.2, the script was almost entirely rewritten.
+The idea was not only to modernize the script, but also make the
+application more compatible with the Slackware architecture and to
+be as easy to "just install and run the app". Also to note: 
+The control app titled unbound-countrol is enabled by 
+default but can be disabled in unbound.conf. It's secure, binds
+to localhost and can't be used by non-root users.
