      ipv6calc is a small utility to manipulate (not only) IPv6 addresses and
      is able to do other tricky things. Intentions were convering a given
      IPv6 address into compressed format, convering a given IPv6 address into
      the same format like shown in /proc/net/if_inet6 and (because it was not
      difficult) migrating the Perl program ip6_int into.
      Now only one utiltity is needed to do a lot.
