+automatically to tile the screen without gaps or overlap, maximising screen
+use.  All features of the window manager are accessible from the keyboard: a
+mouse is strictly optional.  xmonad is written and extensible in Haskell.
+ Custom layout algorithms, and other extensions, may be written by the user in
+config files.  Layouts are applied dynamically, and different layouts may be
+used on each workspace.  Xinerama is fully supported, allowing windows to be
+tiled on several screens.")
