VirtueMart: A virtual ecommerce solution
If you run an ecommerce site, you may want a content management system (CMS) to help manage your online product line. VirtueMart, available under the GNU GPL and fully integrated with Joomla!, does that and more. It provides a full ecommerce solution in a LAMP environment.
VirtueMart has a long history, going back several years through different incarnations. Its oldest ancestor is phpShop, a PHP-powered, standalone shopping-cart application that's still in development. Then it became mambo-phpShop, a Mambo component, fully integrated within that CMS. VirtueMart finally got its current name in June 2005. Its current stable version is 1.0.13a, but version 1.1 is in beta.
