Package which provides a method to create UPC-A barcode using GD library.
Slightly Modified Upca.php to get Upce.php I needed a way to print UPC-E bar codes on a PHP page. The Image_Barcode2 class seemed like the best way to do it, so I modified UPC-A to print in the UPC-E format. Checked the bar code tables against some documentation below (no errors) and validated the changes with my phone app "Barcode Scanner"
