c
c     o Optim_Initmod is called before the optimization. It sets a first guess
c       of the parameter vector. It may also contain the initialization
c       of the model.

c     --> Presently not implemented, since the control vector and the

c         in CPP_OPTIONS.h. The subroutine *ecco_ControlPack* will then
c         non-dimensionalize its output and *ecco_ControlUnPack* will
c         dimensionalize its input.
