README

A GTIN is a string of digits that uniquely identifies a trade item (a product that is bought and sold). A GTIN is globally unique, meaning that no two products in the world share the same GTIN.

This library provides a straightforward way by which a number can be determined to be a valid GTIN or suspected of being invalid in some way.
