The first presentable version of a script to start a single instance
forecast from a single member of a multi-instance forecast,
as is generated by assimilation runs.  
It can build a 'hybrid' case, which uses the CAM initial file to start,
just like the assimilations, or a 'branch' case, which will do an
exact restart from the CAM restart file.
This will be useful for seeing what effects the initialization 
procedure has.
The script has been tested to build both cases,
but the cases have not been run (except for an earlier version of the
script, for a 'branch' case).
It has not been reviewed.

+# Purpose
+#
+# This script is designed to set up, stage, and build a single-instance run
+# of CESM2 using an Fxxx compset, in which CAM, CLM, and CICE are active
+# and the initial conditions are taken froma single instance of a
+# multi-instance CAM forecast (the "reference case" or "REFCASE"). 
+# The case described here should have the exact same set of active physics
+# as the REFCASE, so that the restart files have matching lists of variables.
+
+# ==============================================================================
+# case options:
+#
+# case          The value of "case" will be used many ways; directory and file
+#               names both locally and on HPSS, and script names; so consider
+#               its length and information content.
+# compset       Defines the vertical resolution and physics packages to be used.
+#               Must be a standard CESM compset; see the CESM documentation.
+# compset_args  The local variable passed to create_newcase, which contains $compset
+#               and any signal(s) that this compset is non-standard.
+# resolution    Defines the horizontal resolution and dynamics; see CESM docs.
+#                  T85           ... eulerian at ~ 1 degree
+#                  ne30np4_gx1v6 ... SE core at ~ 1 degree
+#                  f09_f09       ... FV core at ~ 1 degree
+#               BUG 1384 may apply, check if ocean and atm/land must be at same resolution.
+#               Notes about the creation of the 0.25x0.25 ocean + 1deg FV  resolution are in
+#               /glade/work/raeder/Models/CAM_init/SST/README"
+# user_grid     Tells create_newcase whether $resolution has any user defined grids,
+#               such as the high resolution SST grid, and where to find the definition of that resolution.
+# cesmtag       The version of the CESM source code to use when building the code.
+#               A directory with this name must exist in your home directory,
+#               and have SourceMods in it. See the SourceMods section.
+#               http://www.image.ucar.edu/pub/DART/CESM/README
+# sourcemods    DART no longer requires a SourceMods directory in order to work with CESM.
+#               If you have modifications to CESM, they should be provided in a 
+#               CESM-structured SourceMods directory, which this script expects to be in 
+#               $user/$cesmtag/SourceMods.
