5      ==============================      ==============================
6    
7    o model/src, coriolis setting:
8      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
9        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
10        files (selectCoriMap=3) with any grid.
11      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
12    o pkg/seaice/seaice_growth.F:
13        a few cosmetic changes that reduce the number of lines of code
14    o pkg/obcs: add boundary conditions following Stevens (1990)
15      - the code follows old MOM/NAOSIM code
16      - so far it is only implemented for the eastern and western boundaries
17        and NOT for pTracers
18    o pkg/rbcs:
19      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
20        beginning of the first rbcs forcing period.
21      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
22        offline package, i.e., one file per time, labeled by iteration number;
23        deltaTrbcs sets the timestep with which the data was generated;
24        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
25      - rbcsForcingCycle=0 makes forcing non-cyclic.
26      - make arithmetic safe for negative times and odd forcing periods.

29    o pkg/seaice:
30        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
31    o pkg/obcs:
32       New S/R to copy tracer value from the OB location to narrow band region
33        (width = same as overlap) beyond the OB: preserve OB value (needed for
34        high-order scheme) which were overwritten by EXCH call if in overlap
35        region. Applied to theta, salt, ptracer and advected seaice variables.
36       With seaice: use maskInC in similar way as in gad_advection.F,
37        in seaice_advection.F and advect.F.
38       Update output of experiment seaice_obcs and change exp4 to test OBCS with
39        4th order Adv.Scheme. for pasive salt and ptracer.
40    o tools/genmake2:
41      - when looking for an optfile (not specified), only search for Fortran compiler
42        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
43      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
44        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
45      - set default for CPP to "cpp -traditional -P" (was the case without specifying
46        an optfile, but otherwise default was just "cpp".
47      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
48      - when "CC" is not set in the optfile, look for possible C compiler
49        (instead of just setting CC=cc)
50      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
51        => add a ".F" to ".o" rule for source files with no "#include" (such as
52           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
53      - move gfortran before g77 in list of possible Fortran compiler (consistent
54        with reference compiler switch from g77 to gfortran)
55  o pkg/seaice:  o pkg/seaice:
56    o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to    o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
