A command-line {\em switch} is (generally) either on or off; e.g., the
(\tr{simplCore/SimplCore.lhs), and in the STG-to-STG processing loop
(\tr{simplStg/SimplStg.lhs}).
-We use function @classifyOpts@ to take raw command-line arguments from
-@GetArgs@ and get back the @CmdLineInfo@, which is what we really
-want.
