+POS Second EAN13
+================
+
+This module adds a second EAN13 field on products. This feature has been asked by librairies that often have the same book available from 2 different sources with different EAN13 (to keep things simple, I didn't want to handle N EAN13 ; a second EAN13 was enough for most cases). This module also provides a patch to apply on the javascript of the official *point_of_sale* module.
+
+This module has been written by Alexis de Lattre from Akretion <alexis.delattre@akretion.com>.
