+%%% @doc Callback module for ct_telnet for talking telnet
+%%% to a unix host.
+%%% 
+%%% <p>It requires the following entry in the config file:</p>
+%%% <pre>
+%%% {unix,[{telnet,HostNameOrIpAddress},
+%%%        {port,PortNum},
+%%%        {username,UserName},
+%%%        {password,Password}]}.
+%%% </pre>
+%%%
+%%% <p>To talk telnet to the host specified by
+%%% <code>HostNameOrIpAddress</code>, use the interface functions in
+%%% <code>ct</code>, e.g. <code>open(Name), cmd(Name,Cmd), ...</code>.</p>
+%%%
+%%% <p><code>Name</code> is the name you allocated to the unix host in
+%%% your <code>require</code> statement. E.g.</p>
+%%% <pre>   suite() -> [{require,Name,{unix,[telnet,username,password]}}].</pre>
+%%% <p>or</p>
+%%% <pre>   ct:require(Name,{unix,[telnet,username,password]}).</pre>
+%%%
+%%% <p>Note that the <code>{port,PortNum}</code> tuple is optional and if
+%%% omitted, default telnet port 23 will be used.</p>
