Please take a look at OpenEdit framework for CMS:

• SEO friendly. HTML based web sites. No ugly PHP or ASP style syntax in your HTML.
• Fast setup. No external dependencies. No database to setup. Just unzip and run.
• Design focused. Flexible template engine that uses your custom CSS / HTML. Layout within layout reusability. Clean separation of look and feel from content. No display limitations.
• Stable. Built-in plugin installer allows live upgrades and installations of plugins. Make configuration changes without restarting the server.
• Full featured. Enterprise grade plugins such as eCommerce, Digital Asset Management, Blogs, Events Calendar, Site Search, optional db plug-in, Flex and more.
• Low maintenance. Never again copy, paste, and maintain similar HTML code. Use OEF's multiple fallback to extend any part of the OpenEdit Framework or extend any plugin without losing the ability to upgrade.
• Reusable. Use OEF's fallback to create multiple unique instances of a single plugin within a single OEF site.
• Speed. Screaming fast performance and low memory usage.
• Accessible. Edit files quickly without recompiling or caching problems. Browser based editing tools. No desktop application required.
• Interoperability. Use as much or as little OEF as you like. XML based for easy integration with your existing infrastructure.
• Collaborative environment. Permission based architecture for multiuser collaboration
