Introduction
Spectrwm is a small dynamic tiling window manager for X11. It tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact and fast.
Spectrwm is a beautiful pearl! For it too, was created by grinding irritation. Nothing is a bigger waste of time than moving windows around until they are the right size-ish or having just about any relevant key combination being eaten for some task one never needs. The path of agony is too long to quote and in classical OpenBSD fashion (put up, or hack up) a brand new window manager was whooped up to serve no other purpose than to obey its masters.
