This is the `netkey' kernel key-management service (the PF_KEY analogue

Browse source 
to PF_ROUTE) from NRL's IPv6 distribution, heavily modified by me for
better source layout, formatting, and textual conventions.  I am told
that this code is no longer under active development, but it's a useful
hack for those interested in doing work on network security, key management,
etc.  This code has only been tested twice, so it should be considered
highly experimental.
