+C-- Collect here, in a single option-file, options to control which optional
+C   features to compile in packages AUTODIFF, COST, CTRL, ECCO, CAL and EXF.
+C   If used, this option-file needs to be directly included in CPP_OPTIONS.h
+C   Although this method, inherited from ECCO setup, has been traditionally
+C   used for all adjoint built, work is in progess to allow to use the
+C   standard metod (each of the above pkg get its own options from its
+C   specific option-file) also for adjoint built.
