title: magento example module
body: <p>I'm reading through chapter 4 of the magento developers guide which explains how to build a shipping module I've built the config.xml put it in the proper place, put the MagentoBook_ShippingModule.xml file  where it needs to go then it tells me I can configure it in the admin panel but it doesn't show up do I need to reboot the server or something for it to take effect ?</p>
