     Notes on tags used in MITgcmUV
     ==============================
 
-o pkg/seaice/seaice_growth.F: use a different time constant for freezing
-  ice due to supercooled sea water, hardwired to SEAICE_deltaTtherm/0.1
-o gad_som : fix flux output (& diagnostics) to have same units as other
-  advection scheme fluxes (was previously multiplied by deltaT).
+o pkg/mypackage: 
+  - add example of read/write pickup for state-var ; 
+  - add entry points to the main code for state-vars diags & write-pickup.
+o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
+  transitions for useExfYearlyFields
+  - add new subroutine that determines the file to read from for 
+    use*YearlyFields = .TRUE. and .FALSE.
+  - add a verification experiment to global_with_exf that tests 
+    useExfYearlyFields with USE_EXF_INTERPOLATION defined
+o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in 
+  analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new 
+  subroutines (which could be generated from a template, because they are 
+  almost identical), for now they are included in obcs_prescribe_read.F for
+  simplicity
+o pkg/exf:
+  - add a little more diagnostic to exf_interp_read (in analogy to 
+    mds_read_field, can be turned off with debugLevel < debugLevA=1)
+  - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
+    ugly but fast by unrolling short inner loops, inserting a unroll=8 
+    directive in routine lagran, and splitting a loop and making do while the
+    outermost loop (the latter requires the intoduction of index arrays)
+o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
+o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
+  http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
+o verification/seaice_obcs: updated for restart test and latest options
+o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
+  ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
+  for now this is only available for the C-grid code and also within
+  #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
+
+checkpoint59m
+o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
+  and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
+o gad_som : fix flux output (& diagnostics) to have same units as other   
+  advection scheme fluxes (was previously multiplied by deltaT).   
 o added verification/seaice_obcs both to test seaice open boundaries
   and to provide an example matlab scrpt for generating them
 o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
