-- $usage
--
-- 1. In xmonad.cabal change:
--
-- > build-depends: base>=2.0, X11>=1.2.1, X11-extras>=0.2, mtl>=1.0, unix>=1.0
--
-- to
--
-- > build-depends: base>=2.0, X11>=1.2.1, X11-extras>=0.2, mtl>=1.0, unix>=1.0, readline >= 1.0
--
-- 2. In Config.hs add:
--
-- > import XMonadContrib.XPrompt
-- > import XMonadContrib.ShellPrompt
--
-- 3. In your keybindings add something like:
--
-- > , ((modMask .|. controlMask, xK_x), shellPrompt defaultXPConfig)
--
-- %cabalbuilddep readline>=1.0
-- %import XMonadContrib.XPrompt
-- %import XMonadContrib.ShellPrompt
