     Notes on tags used in MITgcmUV
     ==============================
 
+o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
+o changes to permit hi-res, cubed-sphere, configuration
+  - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
+  - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
+  - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
+    of surface winds for the cube
+  (A verification experiment, based on global_ocean.cs32x15, but with
+   pkg/seaice turned on and with on-the-fly interpolation from the NCEP
+   Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
+   complete with example surface forcing files and matlab scripts to look
+   at the output and compare it with that of global_ocean.cs32x15.)
+o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
+   but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
+   to conform to the common rule.
+o check-in the first version of the coupler + interfaces for multi-components 
+   set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
+   - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
+   - atmosphere: use pkg aim_v23 ; no sea-ice for now. 
+   - ocean and atmos. share the same horizontal grid (no interpolation).
+   - exchanges between component and coupler is done in forward_step
+
+checkpoint52d_pre
+o surface flux time-av diagnostic modified for NLFS & RealFreshWater 
+o add call to AIM pendant S/R in external_forcing & external_fields_load.F
+
+checkpoint52c_post
+o Fixing OPTIONS files for use of exf:
+  - ALLOW_ECCO not needed
+  - ECCO_CPPOPTIONS.h should not be included from
+    EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
+    as has been the case in the past
+  - All cal/exf related options are currently set in
+    single header file. Should remain so until we
+    agree on a consistent new policy.
+o Removed all CPP options for cal package.
+  cal has no more CPP options.
+o modified STOREs in GAD_ADVECTION
+o corrected key comp. for passkey
+
+checkpoint52b_post
+o new version: "thsice" of thermodynamic sea-ice pkg:
+ - only 1 call from "forward_step"; conserve energy, fresh-water & salt. 
+ - modify fluxes but do not change theta directly;
+ - light cleaning of bulk_force pkg (still needed with thsice).
+ - add forcing fields + data files in global_ocean.cs32x15/inp_thsice 
+   + output_thsice.txt to test thsice & bulk_force pkgs.
+o put back grid & coriolis monitor output.
+checkpoint52b_pre
+
+o call "do_the_model_io" at the beginning (=> dump initial state) 
+o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
+o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
+  (need info on NUMBER_OF_PTRACERS)
+o missing PTRACERS headers in some routines
+o default tamc.h in pkg/autodiff supposed to crash
+  to ensure proper customization
+
 checkpoint52a_post
 o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
   - moved surfaceTendencyTice from pkg/seaice to main code
