#  This script will tar up all 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 ruc2a data directory and saves selected
#  files into four different tar files, where each tarfile contains
#  data for 6 forecast cycles.  For example, data files from the 00Z through 
#  05Z runs are saved together in a tar file labelled as *YYYYMMDD00-05.tar.  
#
#  Usage: rhist_saveruc.sh Directory Date(YYYYMMDDHH format)
#
#  Where: Directory  = Directory to be tarred.
#         Date(YYYYMMDDHH format) = Day that the tar file should be saved under.
