-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Layout.Maximize
--
-- Then edit your @layoutHook@ by adding the Maximize layout modifier:
--
-- > myLayouts = maximize (Tall 1 (3/100) (1/2)) ||| Full ||| etc..
-- > main = xmonad defaultConfig { layoutHook = myLayouts }
--
-- For more detailed instructions on editing the layoutHook see:
--
-- "XMonad.Doc.Extending#Editing_the_layout_hook"
--
-- In the key-bindings, do something like:
--
-- > , ((modMask x, xK_backslash), withFocused (sendMessage . maximizeRestore))
-- > ...
