+
+Takes a bank transaction ID (as parameter C<bank_transaction_id> and
+tries to post its amount to a certain number of invoices (parameter
+C<invoice_ids>, an array ref of database IDs to purchase or sales
+invoice objects).
+
+The whole function is wrapped in a database transaction. If an
+exception occurs the bank transaction is not posted at all. The same
+is true if the code detects an error during the execution, e.g. a bank
+transaction that's already been posted earlier. In both cases the
+database transaction will be rolled back.
+
+If warnings but not errors occur the database transaction is still
+committed.
+
+The return value is an error object or C<undef> if the function
+succeeded. The calling function will collect all warnings and errors
+and display them in a nicely formatted table if any occurred.
+
+An error object is a hash reference containing the following members:
