initialise :: IO ()
Set up the environment so that the terminal passes characters directly into the Haskell program, for immediate interpretation by the line editor.
restore :: IO ()
Restore the environment so that the terminal is usable in normal mode once again.
getLineEdited :: String -> IO (Maybe String)
delChars :: String -> IO ()
Remove the given string from immediately behind (to the left of) the current cursor position.
testIt :: IO ()
A simple interactive test for the line-editing functionality.
