-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Layout.LayoutCombinators
--
-- Then edit your @layoutHook@ to use the new layout combinators. For
-- example:
--
-- > myLayout = (Tall 1 (3/100) (1/2) *//* Full)  ||| (Tall 1 (3/100) (1/2) ***||** Full) ||| Full ||| etc..
-- > main = xmonad def { layoutHook = myLayout }
--
-- For more detailed instructions on editing the @layoutHook@ see:
--
-- "XMonad.Doc.Extending#Editing_the_layout_hook"
--

-- $combine
-- Each of the following combinators combines two layouts into a
-- single composite layout by splitting the screen into two regions,
-- one governed by each layout.  Asterisks in the combinator names
-- denote the relative amount of screen space given to the respective
-- layouts.  For example, the '***||*' combinator gives three times as
-- much space to the left-hand layout as to the right-hand layout.
