54    "minimal" test case:
55     provide an example of a minimal set-up which only compiles eesupp/src
56     and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
57    
58    code_min:
59      CPP_OPTIONS.h (standard version, needed here since model/inc is not linked)
60      packages.conf (2 pkgs: exch2 & debug)
61      main.F        (copied from eesupp/src, but skip the call to THE_MODEL_MAIN)
62      SIZE.h        (same as code/SIZE.h)
63      SIZE.h_mpi    (same as code/SIZE.h_mpi)
64    
65    input_min
66      eedataa       (standard version)
67      eedata.mth    (to test running 2 threads)
68      data.exch2.mpi (to test blank-tiles with exch2 and MPI built)
69    
70    to build:
71     in order not to compile model/src, need to:
72     either put (in build dir) a "genmake_local" file with STANDARDDIRS="eesupp"
73     - or -
74     use genmake2 command line: "genmake2 -standarddirs eesupp" -mods ../code_min"
