#define USAGE "\
mppncscatter -- Decomposes single NetCDF file into many files (converse to mppnccombine).  The output files are created in the current working directory by default and prefixed with the input file name, i.e. in.nc.0000 ...\n\
\n\
Usage: mppncscatter [OPTION...] in.nc\n\
\n\
  -h, --help           Give this usage message.\n\
      --usage          \n\
  -i, --io-layout-x N  Set io-layout for X dimension.\n\
  -j, --io-layout-y N  Set io-layout for Y dimension.\n\
  -n, --dry-run        Run without writing files.\n\
  -p, --prefix PATH    Prefix path for output files.\n\
  -s, --start N        Start file name suffix numbers from N (default is 0).\n\
  -V, --verbose        Progressively output messages to stdout.\n\
  -v, --version        Print program version.\n\
  -w, --width N        Width for output filename suffix digits.\n\
                       -w 4 (default) creates in.nc.0000 ...\n\
  -x, --npx N          Try to split domain evenly into N columns.\n\
  -X, --xdims d1,...   List of X dimension names to scatter\n\
                       (for those not detectable through metadata).\n\
  -y, --npy N          Try to split domain evenly into N rows.\n\
  -Y, --ydims d1,...   List of Y dimension names to scatter\n\
                       (for those not detectable through metadata).\n\
