Usage:    whois-srv [-H] [-d] [-b|-w] [-s service] [-h host] [-p port] key

Options:  -h host      Whois server locator. Default: whois.ripe.net [0][2]
          -p port      Port to send query to. Default: SRV RR else -s [1]
          -s service   Whois service symbolic name. Default: whois
          -H           Display this help and exit
          -d           Enable debugging output
          -b           Boring mode. Act like a normal client, ignore SRVs
	  -w           Wacky mode. Guess SRVs from query string

This client respects SRV record priorities. Because it makes one
query per invocation SRV weights are meaningless and are ignored.

[0]  SRV records abstract service locator names in the place of DNS
hostnames. For example it is possible with SRVs to say ``the whois
service of whois.foo.com is provided by a host called bigserver.isp.net
on port 756'', should one wish. Therefore in SRV mode this client
initially uses the value of -h, or its default, to form an SRV query.
The SRV record itself will then tell us what real host to contact.
     Should there be no SRV record, or if called using -b, this client
will treat -h, or its default, as the name of the host to query. That
is, it reverts to the behaviour of a ``normal'' client.

[1]  The port to connect may be determind in one of three ways. In order
of precedence they are:
 1. specified by -p
 2. retrieved in an SRV record, if applicable
 3. the port found for -s, or its default, by getservbyname()

[2]  In wacky mode -h, or its default, is used as the name of the host
to query if no SRV RRs can be found.
