8  =====================================  Preprocessed OceanInversion input files are available
9    under directories region_mask, takahashi, and
10    atm_co2 in this package.  All netcdf input files
11    have been converted to binary format in order to avoid
12    having to link netcdf library with MITgcm code.  See
13    respective README files in each directory for details.
14    
 To run a pkg/ptracers test case using salt initial and boundary conditions:  
15    
16    ===============================================
17    First check that pkg/ptracers works OK by using
18   cd MITgcm/bin  salinity initial and boundary conditions
