#
#	back_act will maintain a set of `old' active files
#	in the DB directory where they can be used by nngoback
#	to backtrack the rc file a number of days.
#
#	It should be invoked by cron every day at midnight.
#	It should run as user `news'!
#
#	Call:  back_act [days]
#	Default: keep copy of active file for the last 14 days.
