   3 #  This script loops through each overdue item, determines the fine,
   4 #  and updates the total amount of fines due by each user.  It relies on
   5 #  the existence of /tmp/fines, which is created by ???
   6 # Doesnt really rely on it, it relys on being able to write to /tmp/
   7 # It creates the fines file
   8 #
   9 #  This script is meant to be run nightly out of cron.

  55 This script calculates and charges overdue fines
  56 to patron accounts.  The Koha system preference 'finesMode' controls
  57 whether the fines are calculated and charged to the patron accounts ("Calculate and charge");
  58 calculated and emailed to the admin but not applied ("Calculate (but only for mailing to the admin)"); or not calculated ("Don't calculate").
  59
  60 This script has the following parameters :
  61     -h --help: this message
  62     -l --log: log the output to a file (optional if the -o parameter is given)
  63     -o --out:  ouput directory for logs (defaults to env or /tmp if !exist)
