This is a simple rwhois command line client. It does not handle
registrations or security and currently does not follow referrals.
It uses the RWhois C Client library and is a good example of how
to use that library. The minimal configuration needed is done in
config.h by simply setting the default server and port to connect
to when the -s and -p options are not given.

The man page rwhois.1 has more information on arguments and
their meaning.
