  42
  43  Options:
  44    --help or -h                Brief usage message
  45    --man                       Full documentation
  46    -n fines_to_process         How many fines to process; if left off will
  47                                process all
  48    -m date_format              What format the dates are currently in; 'us'
  49                                or 'metric' (REQUIRED)
  50    -d                          Run in debugging mode
  51
  52 =head1 DESCRIPTION
  53
  54 This script fixes the date code in the description of fines. Previously, the
  55 format of this was determined by which script you were using to update fines (see the -m option)
  56
  57 =over 8
  58
  59 =item B<--help>
  60
  61 Prints a brief usage message and exits.
  62
  63 =item B<--man>
  64
  65 Prints a full manual page and exits.
  66
  67 =item B<-n>
  68
  69 Process only a certain amount of fines. If this option is left off, this script
  70 will process everything.
  71
  72 =item B<-m>
  73
  74 This required option tells the script what format your dates are currently in.
  75 If you were previously using the fines2.pl or fines-sanop.pl script to update
  76 your fines, they will be in 'metric' format. If you were using the fines-ll.pl
  77 script, they will be in 'us' format. After this script is finished, they will
  78 be in whatever format your 'dateformat' system preference specifies.
  79
  80 =item B<-d>
  81
  82 Run in debugging mode; this prints out a lot of information and should be used
  83 only if there is a problem and with the '-n' option.

 101 $0: Fix the date code in the description of fines
 102
 103 Due to the multiple scripts used to update fines in earlier versions of Koha,
 104 this script should be used to change the format of the date codes in the
 105 accountlines table before you start using Koha 3.0.
 106
 107 Parameters:
 108   --mode or -m        This should be 'us' or 'metric', and tells the script
 109                       what format your old dates are in.
 110   --debug or -d       Run this script in debug mode.
 111   --limit or -n       How many accountlines rows to fix; useful for testing.
 112   --help or -h        Print out this help message.
