We'll see the readme tool extensions associated with wizards, preferences, properties, and dialogs in Dialogs and wizards and Preferences and properties.
Next, we will look at some more advanced workbench extensions points that you may want to use. Since the readme tool does not contribute to all of these extension points, we will also look at example extensions that are implemented by the platform workbench, the platform help system, and Java tooling (JDT).
