  49 =head1 SYNOPSIS

  51 use C4::Accounts;
  52
  53 =head1 DESCRIPTION

  62
  63 In a default install of Koha the following lost values are set
  64 1 = Lost
  65 2 = Long overdue
  66 3 = Lost and paid for
  67
  68 FIXME: itemlost should be set to 3 after payment is made, should be a warning to the interface that a charge has been added
  69 FIXME : if no replacement price, borrower just doesn't get charged?
