  93
  94 =head1 SYNOPSIS
  95
  96   use C4::Overdues;
  97
  98 =head1 DESCRIPTION
  99
 100 This module contains several functions for dealing with fines for
 101 overdue items. It is primarily used by the 'misc/fines2.pl' script.
 102
 103 =head1 FUNCTIONS
 104
 105 =head2 Getoverdues
 106
 107   $overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } );
 108
 109 Returns the list of all overdue books, with their itemtype.
 110
 111 C<$overdues> is a reference-to-array. Each element is a
 112 reference-to-hash whose keys are the fields of the issues table in the
 113 Koha database.

 186
 187 Calculates the fine for a book.
 188
 189 The issuingrules table in the Koha database is a fine matrix, listing
 190 the penalties for each type of patron for each type of item and each branch (e.g., the
 191 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
 192 members might get a longer grace period between the first and second
 193 reminders that a book is overdue).
 194
 195
 196 C<$item> is an item object (hashref).
 197
 198 C<$categorycode> is the category code (string) of the patron who currently has
 199 the book.
 200
 201 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
 202
 203 C<$days_overdue> is the number of days elapsed since the book's due date.
 204   NOTE: supplying days_overdue is deprecated.
 205
 206 C<$start_date> & C<$end_date> are C4::Dates objects
 207 defining the date range over which to determine the fine.
 208 Note that if these are defined, we ignore C<$difference> and C<$dues> ,
 209 but retain these for backwards-comptibility with extant fines scripts.
 210
 211 Fines scripts should just supply the date range over which to calculate the fine.
 212
 213 C<&CalcFine> returns four values:
 214
 215 C<$amount> is the fine owed by the patron (see above).
 216
 217 C<$chargename> is the chargename field from the applicable record in
 218 the categoryitem table, whatever that is.
 219
 220 C<$daycount> is the number of days between start and end dates, Calendar adjusted (where needed),
 221 minus any applicable grace period.
 222
 223 C<$daycounttotal> is C<$daycount> without consideration of grace period.
 224
 225 FIXME - What is chargename supposed to be ?
 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.
