#  This script will tar up 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).
#  The third argument, if present, indicates whether the tar file 
#  should be written to the 1-year, 2-year, or permanent archive.
#  Valid values for the 3rd argument are "1", "2" or "perm"
#
#  Usage: rhist_savedir.sh Directory Date(YYYYMMDD format) [1|2|perm]
#
#  Where: Directory  = Directory to be tarred.
#         Date(YYYYMMDD format) = Day that the tar file should be saved under.
