#  This script will tar up the data for a given forecast cycle for the
#  directory specified by the first
#  argument ($1) and place the tar file on the HPSS server
#  under ${HPSSOUT}.  The tar file is put in the directory
#  appropriate for data valid for the day specified as the second 
#  command line argument ($2).
#
#  This script breaks up the rtofsglobal directory into two separate
#  tar files.
#  
#  restart: 4 files with the restart files
#  nc: List of files needed for NetCDF; provided by EMC.
#  ab: all files the .a and .b
#  
#
#  Usage: rhist_savertofsglobal.sh Directory Date(YYYYMMDDHH format)
#
#  Where: Directory  = Directory to be tarred.
#         Date(YYYYMMDDHH format) = Day that the tar file should be saved under.
