     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.
