Bug 17600: Standardize our EXPORT_OK

[srvgit] / misc / cronjobs / staticfines.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 ???
# Doesn't really rely on it, it relies on being able to write to /tmp/
# It creates the fines file
#
#  This script is meant to be run nightly out of cron.

This script calculates and charges overdue fines to patron accounts.

If the Koha System Preference 'finesMode' is set to 'production', the fines are charged to the patron accounts.

Please note that the fines won't be applied on a holiday.

This script has the following parameters :
    -h --help: this message
    -v --verbose
    -c --category borrower_category,amount (repeatable)
    -l --library (repeatable)
    -d --delay
    -u --use-borrower-library: use borrower's library, regardless of the CircControl syspref
    -b --borrower borrowernumber: only for one given borrower
