+
+Product packaging are defined at product variant level. It means that if
+a product template has 25 variants, and all of them are sold in the same
+packaging, one must define all the product packaging one by one on the
+variants.
+
+The aim of this module is to be able to define the product packaging at
+template level. It will then create the product packaging on all
+variants automatically.
+
+Features
+--------
+
+- When a product packaging template is created, create the product
+  packaging on all variants;
+- When a product packaging template is updated, update the product
+  packaging on all variants;
+- When a product packaging template is deleted, delete the product
+  packaging on all variants;
+- When a new product variant is created, create all the product
+  packaging defined by the product packaging templates.

+templates, one must have the special group "Products: Can manage
+packaging at template level".
