+/***
+ * The WhoisClient class implements the client side of the Internet Whois
+ * Protocol defined in RFC 954. To query a host you create a
+ * WhoisClient instance, connect to the host, query the host, and finally
+ * disconnect from the host. If the whois service you want to query is on
+ * a non-standard port, connect to the host at that port.
+ * Here's a sample use:
+ * <pre>
+ * WhoisClient whois;
+ *
+ * whois = new WhoisClient();
+ *
+ * try {
+ * whois.connect(WhoisClient.DEFAULT_HOST);
+ * System.out.println(whois.query("foobar"));
+ * whois.disconnect();
+ * } catch(IOException e) {
+ * System.err.println("Error I/O exception: " + e.getMessage());
+ * return;
+ * }
+ * </pre>
