  90 =head1 SYNOPSIS
  91
  92   use C4::Overdues;
  93
  94 =head1 DESCRIPTION
  95
  96 This module contains several functions for dealing with fines for
  97 overdue items. It is primarily used by the 'misc/fines2.pl' script.
  98
  99 =head1 FUNCTIONS
 100
 101 =head2 Getoverdues
 102
 103   $overdues = Getoverdues( { minimumdays => 1, maximumdays => 30 } );
 104
 105 Returns the list of all overdue books, with their itemtype.
 106
 107 C<$overdues> is a reference-to-array. Each element is a
 108 reference-to-hash whose keys are the fields of the issues table in the
 109 Koha database.

 210
 211 Calculates the fine for a book.
 212
 213 The issuingrules table in the Koha database is a fine matrix, listing
 214 the penalties for each type of patron for each type of item and each branch (e.g., the
 215 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
 216 members might get a longer grace period between the first and second
 217 reminders that a book is overdue).
 218
 219
 220 C<$item> is an item object (hashref).
 221
 222 C<$categorycode> is the category code (string) of the patron who currently has
 223 the book.
 224
 225 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
 226
 227 C<$start_date> & C<$end_date> are DateTime objects
 228 defining the date range over which to determine the fine.
 229
 230 Fines scripts should just supply the date range over which to calculate the fine.
 231
 232 C<&CalcFine> returns four values:
 233
 234 C<$amount> is the fine owed by the patron (see above).
 235
 236 C<$chargename> is the chargename field from the applicable record in
 237 the categoryitem table, whatever that is.
 238
 239 C<$units_minus_grace> is the number of chargeable units minus the grace period
 240
 241 C<$chargeable_units> is the number of chargeable units (days between start and end dates, Calendar adjusted where needed,
 242 minus any applicable grace period, or hours)
 243
 244 FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
 245 or "Final Notice".  But CalcFine never defined any value.
