 -- Description: getopt() translated from the BSD getopt(); compatible with the default Unix getopt()
 --[[ Example:
-       for opt, optarg = os.getopt(arg, 'a:b') do
+       for opt, optarg in os.getopt(arg, 'a:b') do
                if opt == 'a' then print(opt .. '=' .. optarg)
                elseif opt == 'b' then print(opt) end -- optarg is nil
        end
