    -- $usage
    -- To use this module, start with the following @~\/.xmonad\/xmonad.hs@:
    --
    -- > import XMonad
    -- > import XMonad.Config.Bluetile
    -- > import XMonad.Util.Replace
    -- >
    -- > main = replace >> xmonad bluetileConfig
    --
    -- The invocation of 'replace' will replace a currently running
    -- window manager. This is the default behaviour of Bluetile as well.
    -- See "XMonad.Util.Replace" for more information.
