# A CVS aware script to tag a release of the CDF runII
# code.
#
# The methodology is:
#
#	checkout the Release package
#
#	If the release.tags file exists for the release
#	to be tagged and a date was NOT specified, run
#	the release.tags script.
#
#	else if the release.tags file does not exist
#
#       if the date was NOT specified, use the date of
#       the last frozen release and run the changed packages
#       script with that date, update the Release package and
#       run the release.tags script.
#
#	else
#
#	if the date was specified, run the changed packages
#	script with the specified date.  Then update the
#	Release package and run the release.tags script.
