     Notes on tags used in MITgcmUV
     ==============================
+
+checkpoint20
+ o Tidied up open-boundaries some more
+ o Added non-hydrostatic code
+ o Fixed some input data
+ o Modified MPI start-up to work in "coupled" context.
+
+checkpoint19
+ o Tidied up directory structure for verification experiments.
+ o Added new code for open boundaries.
+ o Corrected advective terms near boundaries.
+ o Added CPP flag for "old UV" geometry and corrected spherical geometry.
+ o Implemented free-slip/no-slip BCs and del^4 dissipation.
+ o Split default parameters out of ini_parms.F into set_defaults.F.
+
+checkpoint18
+ o Further changes for optional code generation with 
+   CPP - ugh!
+
+checkpoint17
+ o Beginning to incorporating modularity
+   for supporting atmos. and ocean configs.
+ o Small changes for TAMC complinace
+ o New ultra simple test case. Barotropic box
+   configuration "exp0".
+
+checkpoint16
+ o Minor changes to exchange routines to support 
+   accumulation in reverse mode. Adjoint of an
+   assignment is an addition.
+ o Changes to support compilation by TAMC (LR(1) 
+   syntax) and by g77 under Linux ( 72 character
+   limit ).
+
+checkpoint15
+ Rewrote exchange routines to allow
+ o General tile <-> tile connectivity.
+ o TAMC reverse mode flag ( is this really needed? )
+ o Variable width overlap and exchange region widths.
+ o Hooks for sharing data via DMA, Arctic, Memory Channel, 
+   shmput/shmget, VIA, SYSV shmem and every other cool 
+   communication method.
+
+checkpoint14
+ Consistent isomorphism chages made. These allow dynamical core
+ to support both pressure and meters as a vertical coordinate.
+
+checkpoint13
+ Release which corrects global_max problem and a couple
+ of KGM time-averaging diagnostic errors. Also contains
+ a double-gyre experiment setup as well as the baseline
+ 4 degree global template. The double gyre template is
+ organised to allow it to be applied automatically to
+ the baseline configuration.
+
+branch-point-rdot
+ A few tidy-ups have been made bt the real point of this
+ check-point (excuse the pun) is to allow a branch to be
+ made for the purposes of adding the rDot alterations.
+ I don't want to commit the rDot to the main-trunk until
+ we've actually tested it...
+
+checkpoint12
+ Tidy up and added generic genmake script (formerly
+ configure script). 
+ Released to testers.
+
+checkpoint11
+ Re-arranged initialise() and introduced ini_vertical_grid()
+ and ini_masks_etc().
+
+checkpoint10
+ Introduced the configure script.
+ Separated out the diags package.
+ Added template for writing time-averages of tile/intermediate quantities.
+ Updated SIZE.h in exp2 and made the data big-endian.
+
+checkpoint9
+ MPI fix. Filename changes (meta/data). salbin*y stuff.
+ General tidy-up.
+ SST.bin SSS.bin added to verification/exp2
+
+checkpoint8
+ Inludes time-dependant forcing and time-averaging.
+ Works at 4x4 and 2.8125x2.8125 global
+
+checkpoint7-4degree-ref
+ Branch from checkpoint7. Released for application to
+ global modeling and general modeling - process studies, regional
+ model etc.. 
+ Configured for verification/exp2 - 4 degree global, two process.
+
+checkpoint7
+ Created by cnh
+ Simple 4 degree global simulation 
+ configuration.
+ Includes climatological wind, 
+ hydrography, bathymetry etc
+ Does not include Heat Flux and E-P
+
+checkpoint6
+ Created by cnh
+ merged checkpoint5 with CD and 
+ spherical polar code. 
+ Still some problems with GM Redi
+ abd full topography.
+
+checkpoint5
+ Created by AJA
+ contains updates to GM Redi
+ and reordered timestepping loop
+ for Implicit Diffusion.
+
+checkpoint4
+ Created by cnh
+ Contains memory saving macros ( _rdxc etc..) for when
+ grid variations are limited.
+ Contains polynomial coeffs for EOS and knudsen program
+ for generation.
+

  Added extra flags for runtime options

  Restructured kloop in dynamics.F
