  92
  93 =head1 SYNOPSIS
  94
  95   use C4::Overdues;
  96
  97 =head1 DESCRIPTION
  98
  99 This module contains several functions for dealing with fines for
 100 overdue items. It is primarily used by the 'misc/fines2.pl' script.
 101
 102 =head1 FUNCTIONS
 103
 104 =head2 Getoverdues
 105
 106   $overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } );
 107
 108 Returns the list of all overdue books, with their itemtype.
 109
 110 C<$overdues> is a reference-to-array. Each element is a
 111 reference-to-hash whose keys are the fields of the issues table in the
 112 Koha database.

 183     &CalcFine($item, $categorycode, $branch, $days_overdue, $description, $start_date, $end_date );
 184
 185 Calculates the fine for a book.
 186
 187 The issuingrules table in the Koha database is a fine matrix, listing
 188 the penalties for each type of patron for each type of item and each branch (e.g., the
 189 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
 190 members might get a longer grace period between the first and second
 191 reminders that a book is overdue).
 192
 193
 194 C<$item> is an item object (hashref).
 195
 196 C<$categorycode> is the category code (string) of the patron who currently has
 197 the book.
 198
 199 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
 200
 201 C<$days_overdue> is the number of days elapsed since the book's due date.
 202   NOTE: supplying days_overdue is deprecated.
 203
 204 C<$start_date> & C<$end_date> are C4::Dates objects
 205 defining the date range over which to determine the fine.
 206 Note that if these are defined, we ignore C<$difference> and C<$dues> ,
 207 but retain these for backwards-comptibility with extant fines scripts.
 208
 209 Fines scripts should just supply the date range over which to calculate the fine.
 210
 211 C<&CalcFine> returns four values:
 212
 213 C<$amount> is the fine owed by the patron (see above).
 214
 215 C<$chargename> is the chargename field from the applicable record in
 216 the categoryitem table, whatever that is.
 217
 218 C<$daycount> is the number of days between start and end dates, Calendar adjusted (where needed),
 219 minus any applicable grace period.
 220
 221 C<$daycounttotal> is C<$daycount> without consideration of grace period.
 222
 223 FIXME - What is chargename supposed to be ?
 224
 225 FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
 226 or "Final Notice".  But CalcFine never defined any value.

 440 C<$type> will be used in the description of the fine.

 442 C<$description> is a string that must be present in the description of
