bit quick and dirty, and there may still be errors or confusions present.
* NetBSD does not use tcpd, since inetd does internal checks.
* NetBSD uses hosts_options.
* NetBSD inetd does not have `paranoid' mode to automatically reject
paranoid connections without further processing.
* NetBSD can have more than one address on a physical interface.
* Safe_finger comes from the tcp_wrappers package, not included in NetBSD.
* Add RCS ID (at end, because this uses old manpage macros).
