+	  SixXS Automatic IPv6 Connectivity Client Utility
+
+	  AICCU (Automatic IPv6 Connectivity Client Utility) makes it
+	  easy for users to get IPv6 connectivity. After having
+	  requested an account, tunnel and optionally a subnet, AICCU
+	  can be used to automatically configure the tunnel. AICCU
+	  supports TIC (Tunnel Information & Control protocol), which it
+	  uses for retrieving the tunnel configuration information,
+	  AYIYA, which allows tunnels to be created even behind
+	  firewalls and NAT's.
