  75 C4::Circulation::Fines - Koha module dealing with fines
  76
  77 =head1 SYNOPSIS
  78
  79   use C4::Overdues;
  80
  81 =head1 DESCRIPTION
  82
  83 This module contains several functions for dealing with fines for
  84 overdue items. It is primarily used by the 'misc/fines2.pl' script.
  85
  86 =head1 FUNCTIONS
  87
  88 =head2 Getoverdues
  89
  90   $overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } );
  91
  92 Returns the list of all overdue books, with their itemtype.
  93
  94 C<$overdues> is a reference-to-array. Each element is a
  95 reference-to-hash whose keys are the fields of the issues table in the
  96 Koha database.

 196
 197 Calculates the fine for a book.
 198
 199 The issuingrules table in the Koha database is a fine matrix, listing
 200 the penalties for each type of patron for each type of item and each branch (e.g., the
 201 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
 202 members might get a longer grace period between the first and second
 203 reminders that a book is overdue).
 204
 205
 206 C<$item> is an item object (hashref).
 207
 208 C<$categorycode> is the category code (string) of the patron who currently has
 209 the book.
 210
 211 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
 212
 213 C<$start_date> & C<$end_date> are DateTime objects
 214 defining the date range over which to determine the fine.
 215
 216 Fines scripts should just supply the date range over which to calculate the fine.
 217
 218 C<&CalcFine> returns three values:
 219
 220 C<$amount> is the fine owed by the patron (see above).
 221
 222 C<$units_minus_grace> is the number of chargeable units minus the grace period
 223
 224 C<$chargeable_units> is the number of chargeable units (days between start and end dates, Calendar adjusted where needed,
 225 minus any applicable grace period, or hours)
 226
 227 FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
 228 or "Final Notice".  But CalcFine never defined any value.
