/* Like getopt() but with simpler semantics.

   An option has the form ``-<name>''. The special option ``--''

   denotes the end of the option list. An option can be followed by a

   separate argument (on a per option basis).

   On entry OPTIND contains the index of the next element of ARGV that

   needs parsing.  OPTIND is updated to indicate the index of the next

   argument before mi_getopt() returns.

   If ARGV[OPTIND] is an option, that options INDEX is returned.

   OPTARG is set to the options argument or NULL.  OPTIND is updated.

   If ARGV[OPTIND] is not an option, -1 is returned and OPTIND updated

   to specify the non-option argument.  OPTARG is set to NULL.

   mi_getopt() calls ``error("%s: Unknown option %c", prefix,

   option)'' if an unknown option is encountered. */
