What is "olwm"

olwm (OPEN LOOK Window Manager) was the default stacking window manager for OpenWindows, the original X11 desktop environment included with SunOS and Solaris. Its unique characteristic is its implementation of the OPEN LOOK look and feel.

Scott Oaks developed a variant of olwm, called olvwm (OPEN LOOK Virtual Window Manager), which implements a virtual root window with dimensions greater than those of the video display.
