  53
  54 =head1 DESCRIPTION

  64 In a default install of Koha the following lost values are set
  65 1 = Lost
  66 2 = Long overdue
  67 3 = Lost and paid for
  68
  69 FIXME: itemlost should be set to 3 after payment is made, should be a warning to the interface that a charge has been added
  70 FIXME : if no replacement price, borrower just doesn't get charged?
