+Purchase Return
+===============
+
+This module adds the possibility to create and process Return Purchase Orders.
+
+These are orders that users can create to process the return of items to a
+vendor.
+
+* A return PO can be created with or without reference to an existing PO.
+
+* Once a return PO is confirmed, an outbound picking is created, so as to
+  ship the products back to the vendor.
+
+* A user can create a refund bill referencing a return PO.
