+Dante is a circuit-level firewall/proxy that can be used to provide convenient
+and secure network connectivity, requiring only that the server Dante runs on
+has external network connectivity. Dante is used daily by Fortune 100 companies
+and large international organizations, either as a standard SOCKS server or as
+a "reverse proxy".
