description:
Add hf6to4 1.0.
The hf6to4 script can be used to setup IPv6 on your home machine and net-
work for exploring IPv6 without any registrations. 6to4 is a mechanism by
which your IPv6 address(es) are derived from an assigned IPv4 address,
and which involves automatic tunnelling to one or more remote 6to4 hubs,
which will then forward your v6 packets on the 6bone etc. Replies are
routed back to you over IPv4 via (possibly) other 6to4 capable remote
gateways. As such, IPv6-in-IPv4-encapsulated packets are accepted from
all v4-hosts.
XXX this is a rewrite of 6to4 in /bin/sh, no more perl required.

+To configure a 6to4 tunnel, modify the configuration file
+${PKG_SYSCONFDIR}/hf6to4.conf for your system, then run
+
+ ${RCD_SCRIPTS_DIR}/hf6to4 -v start
+
+You should then be able to ping6 www.kame.net.
