stumpwm - 2:22.11-3 main

StumpWM is a window manager written entirely in Common Lisp. It
attempts to be highly customizable while relying entirely on the
keyboard for input. You will not find buttons, icons, title bars,
tool bars, or any of the other conventional GUI widgets.
.
These design decisions reflect the growing popularity of productive,
customizable lisp based systems.
.
The suggested package, slime, lets you control a running StumpWM
session through Emacs.
.
If you need Xinerama support, you need the xdpyinfo utility from the
x11-utils package.
