+      IceWM is a window manager for the X Window System. The goal of IceWM is
+      speed, simplicity, and not getting in the user’s way. It comes with a
+      taskbar with pager, global and per-window keybindings and a dynamic menu
+      system. Application windows can be managed by keyboard and mouse. Windows
+      can be iconified to the taskbar, to the tray, to the desktop or be made
+      hidden. They are controllable by a quick switch window (Alt+Tab) and in a
+      window list. A handful of configurable focus models are
+      menu-selectable. Setups with multiple monitors are supported by RandR and
+      Xinerama. IceWM is very configurable, themeable and well documented. It
+      includes an optional external background wallpaper manager with
+      transparency support, a simple session manager and a system tray.
