-- $usage
-- This module provides a layout inspired by the one used by the wmii
-- (<http://wmii.suckless.org>) window manager.
-- Windows are arranged into groups in a horizontal row, and each group can lay out
-- its windows
--
--   * by maximizing the focused one
--
--   * by tabbing them (wmii uses a stacked layout, but I'm too lazy to write it)
--
--   * by arranging them in a column.
--
-- As the groups are arranged in a 'ZoomRow', the relative width of each group can be
-- increased or decreased at will. Groups can also be set to use the whole screen
-- whenever they have focus.
--
-- You can use the contents of this module by adding
--
-- > import XMonad.Layout.Groups.Wmii
--
-- to the top of your @xmonad.hs@, and adding 'wmii'
-- (with a 'Shrinker' and decoration 'Theme' as
-- parameters) to your layout hook, for example:
--
-- > myLayout = wmii shrinkText def
--
-- To be able to zoom in and out of groups, change their inner layout, etc.,
-- create key bindings for the relevant actions:
--
-- > ((modMask, xK_f), toggleGroupFull)
--
-- and so on.
--
-- For more information on how to extend your layoutHook and key bindings, see
-- <https://xmonad.org/TUTORIAL.html the tutorial> and "XMonad.Doc.Extending".
--
-- Finally, you will probably want to be able to move focus and windows
-- between groups in a consistent fashion. For this, you should take a look
-- at the "XMonad.Layout.Groups.Helpers" module, whose contents are re-exported
-- by this module.
