+%% @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).'''

+%%
+%% <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>

- <p>This module is deprecated and will be removed in Erlang/OTP 18.</p>
- </warning>
- <p>This (experimental) module implements process groups. A process
- group is a group of processes that can be accessed by a common
- name. For example, a group named <c>foobar</c> can include a set
- of processes as members of this group and they can be located on
- different nodes.</p>
- <p>When messages are sent to the named group, all members of
- the group receive the message. The messages are serialized. If
- the process <c>P1</c> sends the message <c>M1</c> to the group,
- and process <c>P2</c> simultaneously sends message <c>M2</c>, then
- all members of the group receive the two messages in the same
- order. If members of a group terminate, they are automatically
- removed from the group.</p>
- <p>This module is not complete. The module is inspired by the ISIS
- system and the causal order protocol of the ISIS system should
- also be implemented. At the moment, all messages are serialized
- by sending them through a group master process.</p>
