simpleargs (hackage): The provided getArgs returns an arbitrary tuple of values instead of a list of Strings.  This means that the number and type (i.e. parseability) of parameters are checked, and reported to the user.  The module is not a substitute for proper error handling (use System.Console.GetOpt for that), but is useful for making quick and dirty command line tools a bit less dirty, without sacrificing the quick part.
