Print some of the working in subroutine DERIV. Quantities printed are:

(A) The geometry using in the derivative calculation.

(B) The gradients of the coordinates flagged for optimization. Units:
kcal/mol/Angstrom and kcal/mol/radian (for angles and dihedrals) These are
the complete gradients, that is, the gradients of the SCF energy plus any
post-SCF quantities such as dispersion and hydrogen bonding.

These are the values that will be passed back from subroutine DERIV.

(C) The values of the coordinates flagged for optimization. Units:
Angstroms and radians.

Some of the working in subroutines within DERIV can be printed, see
`DCART` and `DERNVO`,
