+ * central tool for developers to override options set by QueryPath.
+ * When a QueryPath object is created, it will evaluate options in the
+ * following order:
+ *
+ * - Options passed into qp() have highest priority.
+ * - Options in QueryPath::Options (this class) have the next highest priority.
+ * - If the option is not specified elsewhere, QueryPath will use its own defaults.
+ *
+ * @see qp()
+ * @see QueryPath::Options::set()
+ * @ingroup querypath_util
