+and other derivatives of arbitrary (algebraic or numeric) order.  For mixed
+partial derivatives, the total order of differentiation is calculated by the
+package.  Optional arguments allow specification of points of
+evaluation (ordinary derivatives), or variables held constant (partial
+derivatives), and the placement of the differentiand (numerator or appended).
+The package is built on xtemplate and the configurability it enables,
+extending to differentials (including simple line elements) and jacobians.")
