wumwum is a window manager manager. The idea behind wumwum is to turn any EWMH-compliant window manager into a tiling manager a la "ion" or "awesome". wumwum works by using wmctrl, and adapts itself dynamically to the active window manager. All functionality from the underlying window manager is kept when under wumwum, making it ideal for beginners.
