+%%% @doc Common Test Example Suite Callback module.
+%%%
+%%% <p>This module gives an example of a common test CTH (Common Test Hook).
+%%% There are many ways to add a CTH to a test run, you can do it either in
+%%% the command line using -ct_hook, in a test spec using
+%%% {ct_hook,M} or in the suite it self by returning ct_hook
+%%% from either suite/0, init_per_suite/1, init_per_group/2 and
+%%% init_per_testcase/2. The scope of the CTH is determined by where is it
+%%% started. If it is started in the command line or test spec then it will
+%%% be stopped at the end of all tests. If it is started in init_per_suite,
+%%% it will be stopped after end_per_suite and so on. See terminate
+%%% documentation for a table describing the scoping machanics.
+%%%
+%%% All of callbacks except init/1 in a CTH are optional.</p>
