           16 .Nm
           17 is a simple, tiny DHCP client. It runs until it enters the "Bound"
           18 state, then forks to the background and runs as a daemon to keep
           19 the lease alive.

           48 .Sh BUGS
           49 I'm sure there are plenty. It only currently supports a small subset of
           50 DHCP options, and has been untested on larger networks. It ignores most of
           51 the DHCP options it understands.
