+This module extends the Odoo Point of Sale to prevent to merge lines if product
+is configured.
+
+By default, new line can be merged with a previous one if the informations are the same.
+(same product, same restaurant note, etc...) and if the UoM Category allow it.
+
+The new module add a boolean field 'Mergeable Line' (default True).
+
+If unchecked, the product will never be merged into another line.
+
+That's important in some context, as in the management of returnable products,
+where we want to have a record of all movements.
