-- This is a module for efficient stack traces. This stack trace implementation
-- is considered low overhead. Basic usage looks like this:
--
-- @
-- import GHC.ExecutionStack
--
-- myFunction :: IO ()
-- myFunction = do
--      putStrLn =<< showStackTrace
-- @
--
-- Your GHC must have been built with @libdw@ support for this to work.
--
-- @
-- user@host:~$ ghc --info | grep libdw
--  ,("RTS expects libdw","YES")
-- @
--
-- @since 4.9.0.0
