/**
 * An annotation used to indicate what lint options a checker supports. For example, if a checker
 * class (one that extends BaseTypeChecker) is annotated with
 * {@code @SupportedLintOptions({"dotequals"})}, then the checker accepts the command-line option
 * {@code -Alint=-dotequals}.
 *
 * <p>This annotation is optional and many checkers do not contain an {@code @SupportedLintOptions}
 * annotation.
 *
 * <p>The {@link SourceChecker#getSupportedLintOptions} method can construct its result from the
 * value of this annotation.
