NOTES
-----
1. To run these scripts, you must download and unzip the gzipped tar file
   containing everything. You will need to do the following before using:
   % cd PCMDI/regridding
   % gmake clean
   % gmake
2. These scripts process specified full years. The only one converted
   for our use is Process_CCSM_OcnM. Type the script name to get a
   usage message.
3. All input files are assumed to be CCSM NetCDF format. Output files
   are NetCDF.
4. This script loads 80 map files comprising 2.3 GB to /ptmp/${USER}/maps.
   If any of the map files are scrubbed while the script is executing, it
   may fail. (Note that this never happened during testing.)
5. During the course of execution of this script, intermediate files require
   ~5 GB of disk space for three years per file in the final output. So a
   decade per final output file would require more than 15 GB disk space.
   This is in addition to the 2.3 GB needed by the maps noted in (4).
6. Upon successful exit of the script, the input and output data files have
   been removed from the disk. Of course the output files have been saved
   on the MSS.
