razorCMS began as a databaseless flat file content management system, forked from a project called uCMS. It's structure allowed you to have just the amount of functionality you needed in a flat file CMS solution, adding extensions (blade packs) for further functionality, whilst allowing setup on simple servers with no database. razorCMS gave you base functionality required to run a website, add the extra functionality as you needed it via the blade pack management system. Everything from WYSIWYG editors to SEF URL was added as extra functionality.
