#  This script will tar up the directory specified by the first
#  argument ($1) and place the tar file on the com place for ncos70as,
#  under /hsmuser/climprod.  The tar file is put in the directory
#  appropriate for data valid for the day specified as the second 
#  command line argument ($2).
#
#  Also a list of the files in the tar file is placed in a corresponding
#  directory in /clim/cpccom/output. If this inventory list already exists,
#  it is assumed that the directory has already been saved, and this 
#  script exits with return code 0.
#
#  Usage: savedir.sh Directory Date(YYYYMMDDHH format)
#
#  Where: Directory  = Directory to be tarred.
#         Date = YYYY/YYYYMM that the tar file should be saved under.
