     "Guile-WM is a simple window manager that's completely customizable—you
have total control of what it does by choosing which modules to include.
Included with it are a few modules that provide basic TinyWM-like window
management, some window record-keeping, multi-monitor support, and emacs-like
keymaps and minibuffer.  At this point, it's just enough to get you started.")
