xmonad 0.17.0-2build1 (amd64 binary) in ubuntu kinetic

 Xmonad is a minimalist tiling window manager for X, written in
 Haskell. Windows are managed using automatic layout algorithms,
 which can be dynamically reconfigured. At any time windows are
 arranged so as to maximise the use of screen real estate. All
 features of the window manager are accessible purely from the
 keyboard: a mouse is entirely optional. Xmonad is configured in
 Haskell, and custom layout algorithms may be implemented by the user
 in config files. A principle of Xmonad is predictability: the user
 should know in advance precisely the window arrangement that will
 result from any action.
 .
 This package comes pre-configured with the default configuration. If
 you want to build your custom-configured version, make sure that
 libghc-xmonad-dev is installed and put your configuration in
 ~/.xmonad/xmonad.hs
