hacked up by me to remove the IPv6 stuff (fow now). I renamed
it `keyadmin' since `key' was already taken by the S/Key calculator.
Its purpose is to act as a command-driven interface to the `PF_KEY'
socket domain, analogously to thefunction of route(8) in the
`PF_ROUTE' domain. This program is believed to be exportable, since
it does no actual cryptography itself.
