Goldberg Description

Goldberg is a web deployment environment for your Rails apps. Goldberg provides you with: A login system. Comprehensive yet easy to configure security, featuring roles and their associated permissions. When you set up users you assign each a role. Roles can inherit from other roles recursively. Site navigation through a menu system. The menu items are linked either to controller actions or to pages of content. What menu items a user can see is determined by that user’s permissions. A basic content management system, so you can type up pages and put them in your web site—either in the menu, or linked from other pages.
