-- | This module is a wrapper for the module "Shelly". 
-- The only difference is a main type 'Sh'. In this module 
-- 'Sh' contains a list of results. Actual definition of the type 'Sh' is:
--
-- > import qualified Shelly as S
-- >
-- > newtype Sh a = Sh { unSh :: S.Sh [a] }
--
-- This definition can simplify some filesystem commands. 
-- A monad bind operator becomes a pipe operator and we can write
--
-- > findExt ext = findWhen (pure . hasExt ext)
-- >
-- > main :: IO ()
-- > main = shs $ do
-- >     mkdir "new"
-- >     findExt "hs"  "." >>= flip cp "new"
-- >     findExt "cpp" "." >>= rm_f 
-- >     liftIO $ putStrLn "done"
--
-- Monad methods "return" and ">>=" behave like methods for
-- @ListT Shelly.Sh@, but ">>" forgets the number of 
-- the empty effects. So the last line prints @\"done\"@ only once. 
--
-- Documentation in this module mostly just reference documentation from
-- the main "Shelly" module.
