#
#  1) Compile the chgres_cube program.  Invoke 
#     ../../build_all.sh
#
#  2) Ensure links to the 'fixed' directories are
#     set.  See the ../../fix/link_fixdirs.sh script prolog
#     for details.
#
#  3) Set all config variables.  See definitions 
#     below.
#
#  4) Invoke the driver script for your machine (with no
#     arguments).
#
# Variable definitions:
# --------------------
# EXTRACT_DIR  - Directory where data extracted from HPSS
#                is stored.
# EXTRACT_DATA - Set to 'yes' to extract data from HPSS.
#                If data has been extracted and is located
#                in EXTRACT_DIR, set to 'no'.
# RUN_CHGRES   - To run chgres, set to 'yes'.  To extract
#                data only, set to 'no'.
# yy/mm/dd/hh  - The year/month/day/hour of your desired
#                experiment.  Currently, does not support
#                pre-ENKF GFS data, prior to
#                2012 May 21 00z.  Use two digits.
# LEVS         - Number of hybrid levels plus 1.  To
#                run with 64 levels, set LEVS to 65.
# CRES_HIRES   - Resolution of the hires component of
#                your experiment.
# CRES_ENKF    - Resolution of the enkf component of the
#                your experiment.
# UFS_DIR      - Location of your checked out UFS_UTILS
#                repo.
# OUTDIR       - Directory where the coldstart data output 
#                from chgres is stored.
# CDUMP        - When 'gdas', will process gdas and enkf 
#                members. When 'gfs', will process gfs 
#                member for running free forecast only.
# use_v16retro - When 'yes', use v16 retro parallel data.         
#                The retro parallel tarballs can be missing
#                or incomplete. So this option may not
#                always work. Contact george.gayno@noaa.gov
#                if you encounter problems.
