You could do something like

code:

import System.Environment

main = getArgs >>= main' where
  main' [arg1, arg2] = putStrLn $ "Doing important work "++arg1++"ing these "++arg2++"s."
  main' _            = do
    name <- getProgName
    putStrLn $ "usage: " ++ name ++ " arg1 arg2"

I've had good experiences with applicative option parsing in my projects.

You can always use /= for logical xor.
