FeinCMS is an extremely stupid content management system. It knows nothing about content - just enough to create an admin interface for your own page content types. It lets you reorder page content blocks using a drag-drop interface, and you can add as many content blocks to a region (e.g. the sidebar, the main content region, or something else). It provides helper functions, which provide ordered lists of page content blocks. Adding your own content types is extremely easy.
