%%% @doc Main user interface for the Common Test framework.
%%%
%%% <p> This module implements the command line interface for running
%%% tests and some basic functions for common test case issues
%%% such as configuration and logging. </p>
%%%
%%% <p><strong>Test Suite Support Macros</strong></p>
%%%
%%% <p>The <code>config</code> macro is defined in <code>ct.hrl</code>. This
%%% macro should be used to retrieve information from the
%%% <code>Config</code> variable sent to all test cases. It is used with two
%%% arguments, where the first is the name of the configuration
%%% variable you wish to retrieve, and the second is the <code>Config</code>
%%% variable supplied to the test case.</p>
%%%
%%% <p>Possible configuration variables include:</p>
%%% <ul>
%%% <li><code>data_dir</code> - Data file directory.</li>
%%% <li><code>priv_dir</code> - Scratch file directory.</li>
%%% <li>Whatever added by <code>init_per_suite/1</code> or
%%% <code>init_per_testcase/2</code> in the test suite.</li>
%%% </ul>
%%% @type var_name() = atom(). A variable name which is specified when
%%% <code>ct:require/2</code> is called,
%%% e.g. <code>ct:require(mynodename,{node,[telnet]})</code>
%%%
%%% @type target_name() = var_name(). The name of a target.
%%%
%%% @type handle() = ct_gen_conn:handle() | term(). The identity of a
%%% specific connection.

%%% (if one has been specified with <code>require/2</code> or a

%%%

%%%
%%% <p>If a config variable key has been associated with a name (by
%%% means of <code>require/2</code> or a require statement), the name
%%% may be used instead of the key to read the value:</p>
