        The trigger script executes for every matching <code>target</code>'s
        execution of <code>trigger</code>. The outcome of that
        <code>trigger</code> is passed to the script as a
        <code>outcome</code> object. Based on that the trigger script should
        decide if an incident should either be created or closed.
