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

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

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

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