 C $Name$
  C CPP flags controlling particular source code features
  C o Shortwave heating as extra term in external_forcing.F
- C Note: this should be a run-time option and not necessarily dependent on KPP
+ C Note: this should be a run-time option
- #ifdef ALLOW_KPP
+ #undef SHORTWAVE_HEATING
- #define  SHORTWAVE_HEATING
- #endif
  C o Include/exclude phi_hyd calculation code
  #define INCLUDE_PHIHYD_CALCULATION_CODE
-Line 21 
 C o Include/exclude call to S/R CONVECT
+Line 19 
 C o Include/exclude call to S/R CONVECT
  C o Include/exclude call to S/R CALC_DIFFUSIVITY
  #define INCLUDE_CALC_DIFFUSIVITY_CALL
+ C o Allow latitudinally varying BryanLewis79 vertical diffusivity
+ #undef ALLOW_BL79_LAT_VARY
+ C o Allow full 3D specification of vertical diffusivity
+ #undef ALLOW_3D_DIFFKR
+ C o Include/exclude Implicit vertical advection code
+ #define INCLUDE_IMPLVERTADV_CODE
+ C o Include/exclude AdamsBashforth-3rd-Order code
+ #undef ALLOW_ADAMSBASHFORTH_3
  C o Include/exclude nonHydrostatic code
  #undef ALLOW_NONHYDROSTATIC
-Line 35 
 C o Allow the use of Non-Linear Free-Sur
+Line 45 
 C o Allow the use of Non-Linear Free-Sur
  C   this implies that surface thickness (hFactors) vary with time
  #undef NONLIN_FRSURF
+ C o ALLOW isotropic scaling of harmonic and bi-harmonic terms when
+ C   using an locally isotropic spherical grid with (dlambda) x (dphi*cos(phi))
+ C *only for use on a lat-lon grid*
+ C   Setting this flag here affects both momentum and tracer equation unless
+ C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
+ C   The definition of the flag is commented to avoid interference with
+ C   such other header files.
+ C   The preferred method is specifying a value for viscAhGrid or viscA4Grid
+ C   in data which is then automatically scaled by the grid size;
+ C   the old method of specifying viscAh/viscA4 and this flag is provided
+ C   for completeness only (and for use with the adjoint).
+ C#define ISOTROPIC_COS_SCALING
+ C o This flag selects the form of COSINE(lat) scaling of bi-harmonic term.
+ C *only for use on a lat-lon grid*
+ C   Has no effect if ISOTROPIC_COS_SCALING is undefined.
+ C   Has no effect on vector invariant momentum equations.
+ C   Setting this flag here affects both momentum and tracer equation unless
+ C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
+ C   The definition of the flag is commented to avoid interference with
+ C   such other header files.
+ C#define COSINEMETH_III
  C o Use "OLD" UV discretisation near boundaries (*not* recommended)
  C   Note - only works with  #undef NO_SLIP_LATERAL  in calc_mom_rhs.F
  C          because the old code did not have no-slip BCs
  #undef  OLD_ADV_BCS
+ C o Use LONG.bin, LATG.bin, etc., initialization for ini_curviliear_grid.F
+ C   Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO
+ C   is still useful with, e.g., single-domain curvilinear configurations.
+ #undef OLD_GRID_IO
  C o Execution environment support options
  #include "CPP_EEOPTIONS.h"
