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

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