Icewm - Window Manager with a Taskbar
A window manager for the X Window System that can emulate the look
of Windows '95, OS/2 Warp 3, OS/2 Warp 4, and Motif and tries to
take the best features from those systems. IceWM features multiple
workspaces, opaque move and resize, a taskbar, a window list,
mailbox status, and a digital clock. It is fast and small.
