Wolf CMS simplifies content management by offering an elegant user interface, flexible templating per page, simple user management and permissions, and the tools necessary for file management. It is a fork of Frog CMS, which was itself a PHP migration of the Ruby-on-Rails app Radiant CMS. Wolf is now forging its own development path, although a family resemblance with these two systems can still be seen.
