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 checkaccount
$owed = &checkaccount($env, $borrowernumber, $dbh, $date);
Looks up the total amount of money owed by a borrower (fines, etc.).
C<$borrowernumber> specifies the borrower to look up.
C<$dbh> is a DBI::db handle for the Koha database.
C<$env> is ignored.

=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.
