+%% @doc EXPERIMENTAL support for testing of upgrade.
+%%
+%% This is a library module containing support for test of release
+%% related activities in one or more applications. Currenty it
+%% supports upgrade only.
+%%
+%% == Configuration ==
+%%
+%% In order to find version numbers of applications to upgrade from,
+%% `{@module}' needs to access and start old OTP
+%% releases. A `common_test' configuration file can be used for
+%% specifying the location of such releases, for example:
+%%
+%% ```
+%% %% old-rels.cfg
+%% {otp_releases,[{r16b,"/path/to/R16B03-1/bin/erl"},
+%% {'17',"/path/to/17.3/bin/erl"}]}.'''
+%%
+%% The configuration file should preferably point out the latest patch
+%% level on each major release.
+%%
+%% If no such configuration file is given, {@link init/1} will return
+%% `{skip,Reason}' and any attempt at running {@link upgrade/4}
+%% will fail.
+%%
+%% == Callback functions ==
+%%
+%% The following functions should be exported from a {@module}
+%% callback module.
+%%
+%% All callback functions are called on the node where the upgrade is
+%% executed.
+%%
+%% <dl>
+%% <dt>Module:upgrade_init(State) -> NewState</dt>
+%% <dd>Types:
+%%
+%% <b><c>State = NewState = cb_state()</c></b>
+%%
+%% Initialyze system before upgrade test starts.
+%%
+%% This function is called before the upgrade is started. All
+%% applications given in {@link upgrade/4} are already started by
+%% the boot script, so this callback is intended for additional
+%% initialization, if necessary.
+%%
+%% Example:
+%%
+%% ```
+%% upgrade_init(State) ->
+%% open_connection(State).'''
+%% </dd>
+%%
+%% <dt>Module:upgrade_upgraded(State) -> NewState</dt>
+%% <dd>Types:
+%%
+%% <b><c>State = NewState = cb_state()</c></b>
+%%
+%% Check that upgrade was successful.
+%%
+%% This function is called after the release_handler has
+%% successfully unpacked and installed the new release, and it has
+%% been made permanent. It allows application specific checks to
+%% ensure that the upgrade was successful.
+%%
+%% Example:
+%%
+%% ```
+%% upgrade_upgraded(State) ->
+%% check_connection_still_open(State).'''
+%% </dd>
+%%

+%% <dd>Types:
+%%
+%% <b><c>State = NewState = cb_state()</c></b>
+%%
+%% Check that downgrade was successful.
+%%
+%% This function is called after the release_handler has
+%% successfully re-installed the original release, and it has been
+%% made permanent. It allows application specific checks to ensure

+%% the "To"-release.</li>
+%% <li>Install the "From"-release and start a new node

+%% <li>Perform the upgrade test and allow customized
+%% control by using callbacks:
