GRADIENTS
In a 1SCF calculation gradients are not calculated by default: in
non-variationally optimized systems this could take a lot of time.
GRADIENTS allows the gradients to be calculated. Normally, gradients
will not be printed if the gradient norm is less than 2.0. However, if
GRADIENTS is present, then the gradient norm and the gradients will
unconditionally be printed. Abbreviation: GRAD.
