import qualified Data.Map as M
import ViewDoc

myLogHook :: X ()
myLogHook = do ewmhDesktopsLogHook
               colorSaved

mykeys (XConfig {modMask = modm}) = M.fromList $
   [  ((modm, xK_s), toggleSaveState)
   ,  ((modm .|. shiftMask, xK_s), launchDocuments)
   ]

main = xmonad $ defaultConfig 
       { loghook = myLogHook
       , keys    = (\c -> mykeys c `M.union` keys defaultConfig c)
