+# Driver script to create a cubic-sphere based model grid on Orion.
+#
+# Produces the following files (netcdf, each tile in separate file):
+#   1) 'mosaic' and 'grid' files containing lat/lon and other
+#      records that describe the model grid.
+#   2) 'oro' files containing land mask, terrain and gravity
+#      wave drag fields.
+#   3) Surface climo fields, such as soil type, vegetation
+#      greenness and albedo.
+#
+# Note: The sfc_climo_gen program only runs with an
+#       mpi task count that is a multiple of six.  This is
+#       an ESMF library requirement.  Large grids may require
+#       tasks spread across multiple nodes.  The orography code
+#       benefits from threads.
+#
+# To run, do the following:
+#
+#   1) Set "C" resolution, "res" - Example: res=96.
+#   2) Set grid type ("gtype").  Valid choices are
+#         "uniform"  - global uniform grid
+#         "stretch"  - global stretched grid
+#         "nest"     - global stretched grid with nest
+#         "regional" - stand-alone regional grid
+#   3) For "stretch" and "nest" grids, set the stretching factor -
+#       "stretch_fac", and center lat/lon of highest resolution
+#      tile - "target_lat" and "target_lon".
+#   4) For "nest" grids, set the refinement ratio - "refine_ratio",
+#      the starting/ending i/j index location within the parent
+#      tile - "istart_nest", "jstart_nest", "iend_nest", "jend_nest"
+#   5) For "regional" grids, set the "halo".  Default is three
+#      rows/columns.
+#   6) Set working directory - TMPDIR - and path to the repository
+#      clone - home_dir.
+#   7) Submit script: "sbatch $script".
+#   8) All files will be placed in "out_dir".
