# table rotation script for shifting data from the main table to keep     #
# yule/samhain/beltane happy and fast.                                    #
# the main reason for this is that we had 62568 log entries after         #
# less than a week of real work with yule/samhain/beltane                 #
# this script takes all data which is older than a day and acknowledged   #
# and inserts it into a backup table, also in the main database.          #
