+ * An information presenter shows information available at the text viewer's
+ * current document position. An <code>IInformationPresenter</code> is a
+ * {@link dwtx.jface.text.ITextViewer} add-on.
+ * <p>
+ * An information presenters has a list of  {@link dwtx.jface.text.information.IInformationProvider} objects
+ * each of which is registered for a  particular document content type.
+ * The presenter uses the strategy objects to retrieve the information to present.
+ * </p>
+ * <p>
+ * In order to provide backward compatibility for clients of <code>IInformationPresenter</code>, extension
+ * interfaces are used to provide a means of evolution. The following extension interfaces exist:
+ * <ul>
+ * <li>{@link IInformationPresenterExtension} since version 3.0 introducing
+ *      the ability to handle documents with multiple partitions</li>
+ * </ul>
+ * </p>
+ * <p>
+ * The interface can be implemented by clients. By default, clients use
+ * {@link dwtx.jface.text.information.InformationPresenter} as the standard implementer of this interface.
