/**Specify an option that affects the way the hint works.
 *
 * Only {@code static final String} compile-time constant can be marked with this
 * annotation. The value of the constant will be used as the key to the hint's {@link Preferences}.
 *
 * For hints that consist of a class, all options that are directly enclosed in the class
 * will be used in their source order.
 *
 * For hints that consist of a single method, use {@link UseOptions} to specify which options
 * from the enclosing class should be used. The order of the options will be the order in which
 * they appear in the source code of the enclosing class.
 *
 * The customizer will be generated automatically when {@link BooleanOption} is used.
 *
 * Two keys need to be defined in the corresponding {@code Bundle.properties}:
 * {@code LBL_.}, which will be used as the display name of
 * the corresponding checkbox in the customizer, and {@code TP_.}
 * which will be used as the tooltip of the checkbox.
