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

 201 Calculates the fine for a book.
 202
 203 The issuingrules table in the Koha database is a fine matrix, listing
 204 the penalties for each type of patron for each type of item and each branch (e.g., the
 205 standard fine for books might be $0.50, but $1.50 for DVDs, or staff
 206 members might get a longer grace period between the first and second
 207 reminders that a book is overdue).
 208
 209
 210 C<$item> is an item object (hashref).
 211
 212 C<$categorycode> is the category code (string) of the patron who currently has
 213 the book.
 214
 215 C<$branchcode> is the library (string) whose issuingrules govern this transaction.
 216
 217 C<$start_date> & C<$end_date> are DateTime objects
 218 defining the date range over which to determine the fine.
 219
 220 Fines scripts should just supply the date range over which to calculate the fine.
 221
 222 C<&CalcFine> returns four values:
 223
 224 C<$amount> is the fine owed by the patron (see above).
 225
 226 C<$chargename> is the chargename field from the applicable record in
 227 the categoryitem table, whatever that is.
 228
 229 C<$unitcount> is the number of chargeable units (days between start and end dates, Calendar adjusted where needed,
 230 minus any applicable grace period, or hours)
 231
 232 FIXME - What is chargename supposed to be ?
 233
 234 FIXME: previously attempted to return C<$message> as a text message, either "First Notice", "Second Notice",
 235 or "Final Notice".  But CalcFine never defined any value.

 461 (Note: the following is mostly conjecture and guesswork.)
 462
 463 Updates the fine owed on an overdue book.
 464
 465 C<$itemnumber> is the book's item number.
 466
 467 C<$borrowernumber> is the borrower number of the patron who currently
 468 has the book on loan.
 469
 470 C<$amount> is the current amount owed by the patron.
 471
 472 C<$type> will be used in the description of the fine.
 473
 474 C<$description> is a string that must be present in the description of
 475 the fine. I think this is expected to be a date in DD/MM/YYYY format.
 476
 477 C<&UpdateFine> looks up the amount currently owed on the given item
 478 and sets it to C<$amount>, creating, if necessary, a new entry in the
 479 accountlines table of the Koha database.
