    -- $usage
    -- The simplest way to use this configuration module is to use an
    -- @~\/.xmonad\/xmonad.hs@ like this:
    --
    -- > module Main (main) where
    -- >
    -- > import XMonad
    -- > import XMonad.Config.Arossato (arossatoConfig)
    -- >
    -- > main :: IO ()
    -- > main = xmonad =<< arossatoConfig
    --
    -- NOTE: that I'm using xmobar and, if you don't have xmobar in your
    -- PATH, this configuration will produce an error and xmonad will not
    -- start. If you don't want to install xmobar get rid of this line at
    -- the beginning of 'arossatoConfig'.
    --
    -- You can use this module also as a starting point for writing your
    -- own configuration module from scratch. Save it as your
    -- @~\/.xmonad\/xmonad.hs@ and:
    --
    -- 1. Change the module name from
    --
    -- > module XMonad.Config.Arossato
    -- >     ( -- * Usage
    -- >       -- $usage
    -- >       arossatoConfig
    -- >     ) where
    --
    -- to
    --
    -- > module Main where
    --
    -- 2. Add a line like:
    --
    -- > main = xmonad =<< arossatoConfig
    --
    -- 3. Start playing with the configuration options...;)
