COMA WINDOW MANAGER
A personal, ISC licensed, keyboard driven window manager.
By default it will attempt to create 484px wide frames centered on your screen (which translates to 80 column xterm clients when using the default fixed font).
Coma ties in directly with your shell if properly configured. see the README for more information.
It is perfect for hackers.
Key bindings, frame widths and more are all configurable via $HOME/.comarc. Read manual page after building and installing.
