 -- $example1
--- A layout inspired by the one used by the wmii (<http://wmii.suckless.org>).
--- Windows groups are arranged 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 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.
---
--- To use this layout, add 'wmiiLike' (with a 'Shrinker' and decoration 'Theme' as 
--- parameters) to your layout hook, for example:
---
--- > myLayout = wmiiLike shrinkText defaultTheme
---
--- 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.

+-- $usage
+--
+-- This module provides helpers functions for use with "XMonad.Layout.Groups"-based
+-- layouts. You can use its contents by adding
+--
+-- > import XMonad.Layout.Groups.Helpers
+--
+-- to the top of your @.\/.xmonad\/xmonad.hs@.
+--
+-- "XMonad.Layout.Groups"-based layouts do not have the same notion
+-- of window ordering as the rest of XMonad. For this reason, the usual
+-- ways of reordering windows and moving focus do not work with them.
+-- "XMonad.Layout.Groups" provides 'Message's that can be used to obtain
+-- the right effect.
+--
+-- But what if you want to use both 'G.Groups' and other layouts?
+-- This module provides actions that try to send 'G.GroupsMessage's, and
+-- fall back to the classic way if the current layout doesn't hande them.
+-- They are in the section called \"Layout-generic actions\".
+-- 
+-- The sections \"Groups-specific actions\" contains actions that don't make
+-- sense for non-'G.Groups'-based layouts. These are simply wrappers around
+-- the equivalent 'G.GroupsMessage's, but are included so you don't have to
+-- write @sendMessage $ Modify $ ...@ everytime.
+--
+-- This module exports many operations with the same names as
+-- 'G.ModifySpec's from "XMonad.Layout.Groups", so if you want
+-- to import both, we suggest to import "XMonad.Layout.Groups"
+-- qualified:
+--
+-- > import qualified XMonad.Layout.Groups as G
+--
+-- For more information on how to extend your layour hook and key bindings, see
+-- "XMonad.Doc.Extending".

+-- $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\/xmonad.hs@, and adding 'wmii' 
+-- (with a 'Shrinker' and decoration 'Theme' as 
+-- parameters) to your layout hook, for example:
+--
+-- > myLayout = wmii shrinkText defaultTheme
+--
+-- 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 layout hook and key bindings, see
+-- "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.
