     Notes on tags used in MITgcmUV
     ==============================
 
+o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
+  and add those terms in Vector-Invariant formulation.
+o in ctrl pkg, if ALLOW_CAL, use monthly mean controls 
+  if the control period (xx_hfluxperiod etc) is 0
+o in profiles pkg, clean routines and fix details
+o in ecco pkg, reading ssh data: 
+  fix problem in case the model does not start at iter0=0
+o fix mnc-pickup/restart for ptracers
+o new package prifiles:
+  code to compute profile-based cost by Gael Forget
+  (modifs in ecco, ctrl, autodiff)
+o Benign bug fix in initialization (spotted by M. Mazloff) of
+  ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
+
+checkpoint58c_post
+o adjoint: finish NLFS adjoint and provide reference output in
+  verification/global_ocean.90x40x15/results_ad_nlfs
+o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the 
+  documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
+  SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only 
+  with SEAICE_CGRID defined.
+o move calendarDumps from "data" to "data.cal" and clean-up the code
+  with a simple call to pkg/cal S/R: CAL_TIME2WRITE
+o add useEXF & useCAL flags (for now, set in hard-coded way)
+o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
+  (were missing in NH mode, and wrong in quasihydrostatic mode).
+  waiting for Chris updated version of calc_gw to add those CALLs.
+o fix bug in quasihydrostatic S/R ;
+  add a test for this option: global_ocean.90x40x15.qshyd
+o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
+  (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
+o add on/off flag useOffLine for package OFFLINE
+o seaice: 
+  - modify advection so that it works also on the C-grid
+  - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes 
+    problem in multi-tile runs with C-grid
+  - add flags for clipping ice velocities and/or masking solver forcing
+  - fix drag (ocean on ice) formulation and a bug that caused noise in the
+    C-grid solver
+  - added a few comments to seaice_diffusion.F
+  - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
+    are now exclusive)
+  - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which 
+    required re-ordering the code a little:
+   + make DAIRN global variable (defined in SEAICE)
+   + move computation of the viscosities eta and zeta into a new separate
+     routine (because I need to recompute them in seaice_ocean_stress.F)
+
+checkpoint58b_post
+o AIM+thSIce: fix sign of Short-Wave through the Ice ; 
+  update output.txt of exp. aim.5l_cs.thSI
+o various mnc cleanups and improvements:
+  + shrink lookup tables by factor of ~4
+  + better error reporting when running out of lookup space
+  + able to handle longer path/file names (up to 500 chars)
+o adjoint:
+  - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
+  - TBD: "hidden" mom_vecinv recomp. in dynamics
 o change forcing_In_AB to affects both T,S forcing and Momentum forcing
  (allow to differentiate between forcing components using new integer flags:
   momForcingOutAB=1/0 & tracForcingOutAB=1/0)
