-- | Simple interface to program arguments.

--   Typical usage with no commands:
--   
--   <pre>
--   do (opts,()) &lt;-
--        simpleOptions "ver"
--                      "header"

--                      (flag () () (long "some-flag"))
--                      empty
--      doThings opts
--   </pre>
--   
--   Typical usage with commands:
--   
--   <pre>
--   do (opts,runCmd) &lt;-
--        simpleOptions "ver"
