+ * @defgroup Quadrature Quadrature formulæ
+ *
+ * This module contains the base class Quadrature as well as the
+ * quadrature formulæ provided by deal.II.
+ *
+ * The class QIterated is used, to construct an iterated quadrature
+ * formula out of an existing one, thereby increasing the accuracy of
+ * the formula without increasing the order.
+ *
+ * While the usual quadrature formulæ of higher dimensions
+ * generate tensor products which are equal in each direction, the
+ * class QAnisotropic generates tensor products of possibly different
+ * formulæ in each direction.
+ *
+ * The class QProjector is not actually a quadrature rule by itself,
+ * but it provides functions for computing the quadrature on the
+ * surfaces of higher dimensional cells.
+ *
+ * All other classes in this module actually implement quadrature
+ * rules of different order and other characteristics.
