A(nother) Common Lisp FullScreen Window Manager
CLFSWM is a 100% Common Lisp X11 window manager (based on Tinywm and Stumpwm. Many thanks to them). It can be driven only with the keyboard or with the mouse. . A display contains a root frame and its children. A child can be a window or another frame. The root frame or its children can be the current root. The current root is fullscreen maximized (no decorations, no buttons, no menus: nothing, just the application fullscreen!). . CLFSWM is highly dynamic. By default there is only one frame (the root frame). Other frames are created/deleted on the fly. A window can be in more than one frame, so it can have multiple views of the same windows. . Using CLFSWM is like walking through a tree of frames and windows. Enter in a child to make it the current root and make it fullscreen maximized. Leave it to make its parent the current root.
