-- $usage
-- You can use this module with the following in your Config.hs file:
--
-- > import XMonad.Util.Dmenu
--
-- These functions block xmonad's event loop until dmenu exits; this means that
-- programs will not be able to open new windows and you will not be able to
-- change workspaces or input focus until you have responded to the prompt one
-- way or another.
-- %import XMonad.Util.Dmenu
