%%% @doc Plugin handling test
%%%
%%% This test checks if plugins are loaded correctly.
%%%
%%% It has three applications:
%%% <ol>
%%%   <li>fish. top-level module, has one dependency: `dependsonplugin'.</li>
%%%   <li>dependsonplugin. This depends on some pre-compile actions by the
%%%       plugin. In the test the plugin creates a file `pre.compile' in the
%%%       top-level folder of this application.</li>
%%%   <li>testplugin. This is a plugin application which creates the file.</li>
%%% </ol>
