# adm-rewriteover
#
#		This script runs dexpireover with the -R option, which
#		truely cleans up the overview database. It rewrites the
#		entire database which can take a while but only needs to
#		be run once a week or possibly even once a month.
#
#		dexpireover -a -R is able to cleanout more data from
#		the data.* files whereas dexpireover -a is only able
#		to remove whole data.* files (i.e. it cannot remove the
#		file until the entire contents of the file has expired).
#
#		Called from cron-weekly, but disabled by default
#		since it can cause a corrupted overview database.
#		It's experimental and a bit buggy.
