# Script to update the "speclog" product for one or more MJDs
# from the astrolog directory.  Files of interest are copied from
# $ASTROLOG_DIR/$MJD to $SPECLOG_DIR/$MJD.  Then a "cvs add" and "cvs commit"
# are performed in the $SPECLOG_DIR directory.
#
# Examples:
# Update the relevant log files from $ASTROLOG_DIR/52780 to $SPECLOG_DIR/52780:
#   % speclog_update 52780
# Do the same for the next three MJDs:
#   % speclog_update 52781 52782 52783
