  49 =head1 SYNOPSIS
  50
  51 use C4::Accounts;
  52
  53 =head1 DESCRIPTION
  54
  55 The functions in this module deal with the monetary aspect of Koha,
  56 including looking up and modifying the amount of money owed by a
  57 patron.

  61 =head2 chargelostitem
  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?
