+ * Controller which allows the user to select a region of a component. The user must click on a
+ * point in the component, then drag the mouse pointer whilst keeping the button pressed. During
+ * the dragging, the shape which is drawn will normally be a rectangle.  Other shapes could always
+ * be used such as, for example, an ellipse. To use this class, it is necessary to create a derived
+ * class which defines the following methods:
+ *
+ * <ul>
+ *   <li>{@link #selectionPerformed} (obligatory)</li>
+ *   <li>{@link #getModel} (optional)</li>
+ * </ul>
+ *
+ * This controller should then be registered with one, and only one, component
+ * using the following syntax:
+ *
+ * <blockquote><pre>
+ * {@link Component} component=...
+ * MouseSelectionTracker control=...
+ * component.addMouseListener(control);
