--- Oooh, spooky.
+-- $usage
+-- To wire this up, add:
+--
+-- > import XMonadContrib.UrgencyHook
+--
+-- to your import list in Config. Change your defaultLayout such that
+-- withUrgencyHook is applied along the chain. Mine, for example:
+--
+-- > defaultLayout = Layout $ withUrgencyHook $ windowNavigation wnConfig $
+-- >                          LayoutSelection defaultLayouts
+--
+-- It shouldn't hurt to have the "withUrgencyHook $" at the outermost layer,
+-- as above, as UrgencyHook is a LayoutModifier, and hence passes on any
+-- messages sent to it. Next, add your actual urgencyHook to Config. This
+-- needs to take a Window and return an X () action. Here's an example:
+--
+-- > urgencyHook :: Window -> X ()
+-- > urgencyHook w = do
+-- >     name <- getName w
+-- >     ws <- gets windowset
+-- >     whenJust (W.findIndex w ws) (flash name ws)
+-- >   where flash name ws index =
+-- >               when (index /= W.tag (W.workspace (W.current ws))) $
+-- >               dzen (show name ++ " requests your attention on workspace " ++ show index)
+--
+-- This example stands on the shoulders of the NamedWindows and Dzen modules,
+-- but you can build whatever urgencyHook you like. Finally, in order to make
+-- this compile, open up your Config.hs-boot file and add the following to it:
+--
+-- > urgencyHook :: Window -> X ()
+--
+-- Compile!
