+Product Expiry Simple
+=====================
+
+This module is similar to the official *product_expiry* modules, but much simpler and much better:
+
+* Only one expiry date field instead of 4 !
+* date field instead of datetime
+* No automatic computing of expiry date based on a delay configured on product (not needed in most companies)
+* colored production lot and stock quant tree views depending on expiry dates
+* ability to show stats about expiry dates on quants pivot table (thanks to related stored field on stock.quant)
+
+This module has been written by Alexis de Lattre from Akretion <alexis.delattre@akretion.com>.
