15  * An intro content detector is used when starting the Workbench to determine if
16  * new intro content is available. Since calling this method is part of the
17  * Workbench start sequence, subclasses should be implemented with care as not
18  * to introduce noticeable delay at startup. If an intro content detector
19  * reports new available content, the view part showing the content will be
20  * opened again even if the user had closed it in a previous session. Because of
21  * this, the intro view part should draw the user's attention to the new content
22  * to avoid confusion about why the intro view part was opened again without the
23  * user requesting it.
