Adding A Tab To The Product Screen

1. Declare an admin layout XML file for your module in your config.xml:

2. Create the layout XML in /app/design/adminhtml/default/default/layout/your-module.xml:

3. Create the tab block in {your_module}/Block/Adminhtml/Catalog/Product/Tab.php:

4. Create a data helper to support translation, if your module does not have one already

5. Make the tabs template in /app/design/adminhtml/default/default/template/catalog/product/tab/some-tab.phtml:

        </div>
    </div>
