Koha/misc/fines2.pl

#!/usr/bin/perl

#  This script loops through each overdue item, determines the fine,
#  and updates the total amount of fines due by each user.  It relies on
#  the existence of /tmp/fines, which is created by ???
# Doesnt really rely on it, it relys on being able to write to /tmp/
# It creates the fines file
#
#  This script is meant to be run nightly out of cron.
