-%%% == Logging ==
-%%%
-%%% `ct_telnet' can be configured to uses the `error_logger' for logging telnet
-%%% traffic. A special purpose error handler is implemented in
-%%% `ct_conn_log_h'. To use this error handler, add the `cth_conn_log'
-%%% hook in your test suite, e.g.
-%%%
-%%%
-%%% ```
-%%% suite() ->
-%%% [{ct_hooks, [{cth_conn_log, [{conn_mod(),hook_options()}]}]}].
-%%%'''
-%%%
-%%% `conn_mod()' is the name of the common_test module implementing
-%%% the connection protocol, i.e. `ct_telnet'.
-%%%
-%%% The hook option `log_type' specifies the type of logging:
-%%%
-%%% <dl>
-%%% <dt>`raw'</dt>
-%%% <dd>The sent and received telnet data is logged to a separate
-%%% text file as is without any formatting. A link to the file is
-%%% added to the test case HTML log.</dd>
-%%%
-%%% <dt>`html (default)'</dt>
-%%% <dd>The sent and received telnet traffic is pretty printed
-%%% directly in the test case HTML log.</dd>
-%%%
-%%% <dt>`silent'</dt>
-%%% <dd>Telnet traffic is not logged.</dd>
-%%% </dl>
-%%%
-%%% By default, all telnet traffic is logged in one single log
-%%% file. However, it is possible to have different connections logged
-%%% in separate files. To do this, use the hook option `hosts' and
-%%% list the names of the servers/connections that will be used in the
-%%% suite. Note that the connections must be named for this to work.
-%%%
-%%% The `hosts' option has no effect if `log_type' is set to `html' or
-%%% `silent'.
-%%%
-%%% The hook options can also be specified in a configuration file with
-%%% the configuration variable `ct_conn_log':
-%%%
-%%% ```
-%%% {ct_conn_log,[{conn_mod(),hook_options()}]}.
-%%% '''
-%%%
-%%% For example:
+%% @doc Common Test specific layer on top of telnet client `ct_telnet_client.erl'
%%
-%%% ```
-%%% {ct_conn_log,[{ct_telnet,[{log_type,raw},
-%%% {hosts,[key_or_name()]}]}]}
-%%% '''
-%%%
-%%% <b>Note</b> that hook options specified in a configuration file
-%%% will overwrite any hardcoded hook options in the test suite.
