Summary description: Write differential coefficients easily
Announcement text: ----------------------------------------------------------------------
diffcoeff.sty enables the easy writing of ordinary and partial differential coefficients of arbitrary order. For mixed partials, the overall order (algebraic or numeric) is calculated by the package. Optional arguments specify points of evaluation / variables held constant, and the placement of the differentiand (numerator / appended). Key = value settings tweak the display. Further commands construct analogous coefficients from D, Delta, and delta, and write Jacobians.
Also included is diffcoeffx.sty which is diffcoeff.sty on steroids. The packages use expl3 and xparse from the LaTeX3 bundles, l3kernel and l3packages.
