 # Short-Description: Start or stop stunnel 4.x (SSL tunnel for network daemons)
+# Description:       Starts or stops all configured SSL network tunnels. Each *.conf file in
+#                    /etc/stunnel/ will spawn a separate stunnel process. The list of files
+#                    can be overriden in /etc/default/stunnel, and that same file can be used
+#                    to completely disable *all* tunnels.
