+Account Direct Debit Autogenerate
+=================================
+
+With this module, when you validate a customer invoice whose payment mode is SEPA Direct Debit :
+
+* if a draft Direct Debit order for SEPA Direct Debit already exists, a new payment line is added to it for the invoice,
+
+* otherwise, a new SEPA Direct Debit order is created for this invoice.
+
+This module has been written by Alexis de Lattre from Akretion <alexis.delattre@akretion.com>.
