This module implements the command line interface for running
%%% tests and some basic functions for common test case issues
%%% such as configuration and logging.
%%%
%%% Run this function once before first test.
%%%
%%% From this mode all test case support functions can be executed
%%% directly from the erlang shell. The interactive mode can also be
%%% started from the OS command line with ct_run -shell
%%% [-config File...].
%%%
%%% If any functions using "required config data" (e.g. telnet or
%%% ftp functions) are to be called from the erlang shell, config data
%%% must first be required with ct:require/2.
%%%
%%% Example: Require one node with a telnet connection and an
%%% ftp connection. Name the node a:
%%%
This function returns the matching value(s) or config element(s),
%%% given a config variable key or its associated name
%%% (if one has been specified with require/2 or a
%%% require statement).
%%%
%%% If a config variable is defined in multiple files and you want to
%%% access all possible values, use the all option. The
%%% values will be returned in a list and the order of the elements
%%% corresponds to the order that the config files were specified at
%%% startup.
%%%
%%% If you want config elements (key-value tuples) returned as result
%%% instead of values, use the element option.
%%% The returned elements will then be on the form {Required,Value}
