auto6to4

I wrote a script to activate 6to4 (protocol 41 tunnel to anycast
address) and route/advertise a subnet.  I've just wrapped it inside a
debian package, the idea being that people could go

  apt-get install auto6to4

and, assuming they have a stable first-class IPv4 address, immediately
sans configuration get a stable IPv6 address.  And if they instead go

  apt-get install auto6to4 radvd

then they'd have a subnet for all local hosts that accept
advertisements.  I tried to make it robust, so as to not mess up
anything on a host that doesn't have a first-class IPv4 address, and to
do the right thing on hosts with multiple interfaces, e.g., a host
serving as a NAT router.

I've uploaded the package to experimental.  Before uploading the package
to Debian proper, I was hoping people might have a look at it.  Source
is in the repo git://github.com/barak/auto6to4.git and mirrored in
collab-maint.  Comments / suggestions / patches most welcome.
