I think the idea by Till to separate the args with commas is best, but if you 
don't want to do this, maybe something like that would be o.k. :

let mode_pred = ref true;;
let pred_files = ref [];;
let extra_files = ref [];;
let key2 = ref "";;

Arg.parse [
	"-extra-files", Arg.Clear mode_pred, "extra files";
	"-key2", Arg.Set_string key2, "key2";
	"-pred-files", Arg.Set mode_pred, "pred files"
	]
	(fun name -> if !mode_pred then
		 	pred_files := name :: !pred_files
		else
			extra_files := name :: !extra_files
	) "usage..."
;;


cheers,
 Michael
