In this chapter, we learned how to package and distribute our custom extensions. This knowledge will most certainly be of use if you plan on selling your extensions, or sharing them for free. With this we conclude the chapter and the book. Hopefully, you got enough insight and knowledge for building your own extensions. There are a lot of caveats that you might find along the way. Just remember, Magento has a very active developer community over at http://www.magentocommerce.com/boards and http://magento.stackexchange.com/, so feel free to ask for help.
