+     "sslh is a network protocol demultiplexer.  It acts like a switchboard,
+accepting connections from clients on one port and forwarding them to different
+servers based on the contents of the first received data packet.  Detection of
+common protocols like HTTP(S), SSL, SSH, OpenVPN, tinc, and XMPP is already
+implemented, but any other protocol that matches a regular expression can be
+added.  sslh's name comes from its original application of serving both SSH and
+HTTPS on port 443, allowing SSH connections from inside corporate firewalls
+that block port 22.")
