-- $usage
--
-- This module allows you to run a centrally located script with the text
-- name of a hook.  The script is assumed to be located at @~\/.xmonad\/hooks@.
--
-- For example, if you wanted to run the hook "startup" in your script every
-- time your startup hook ran, you could modify your xmonad config as such:
--
-- > main = xmonad $ defaultConfig {
-- >   ...
-- >   startupHook = execScriptHook "startup"
-- >   ...
-- >   }
--
-- Now, every time the startup hook runs, the command
-- @~\/.xmonad\/hooks startup@ will also.
