C4::Accounts - Functions for dealing with Koha accounts
=head1 SYNOPSIS
use C4::Accounts2;
=head1 DESCRIPTION
The functions in this module deal with the monetary aspect of Koha,
including looking up and modifying the amount of money owed by a
patron.

=item recordpayment
&recordpayment($env, $borrowernumber, $payment);
Record payment by a patron. C<$borrowernumber> is the patron's
borrower number. C<$payment> is a floating-point number, giving the
amount that was paid. C<$env> is a reference-to-hash;
C<$env-E<gt>{branchcode}> is the code of the branch where payment was
made.
Amounts owed are paid off oldest first. That is, if the patron has a
$1 fine from Feb. 1, another $1 fine from Mar. 1, and makes a payment
of $1.50, then the oldest fine will be paid off in full, and $0.50
will be credited to the next one.

Records the fact that a patron has paid off the entire amount he or
she owes.

the account that was credited. C<$amount> is the amount paid (this is
only used to record the payment. It is assumed to be equal to the
amount owed). C<$branchcode> is the code of the branch where payment
was made.
