DFORCE

Print some of the working in the FORCE calculation.

Caution: By default, the geometry is rotated so that the principal moments of inertia are oriented along the Cartesian axes, x, y, and z. This can cause problems in using the printed Hessian matrix. If this is not wanted, add keyword `NOREOR <noreor.html>`__.
