Scwm

A Scheme-configurable X11 manager based on the FVWM2 window-manager framework. Users can write Scheme procedures for menus, bindings and window behaviour, making it a programmable environment for customising a conventional stacking desktop. SCWM was built on the FVWM2 framework and added Scheme as its configuration and extension language, combining an existing X11 manager with programmable policy.
