-/*  Arg_parser reads the arguments in `argv' and creates a number of
-    option codes, option arguments and non-option arguments.
-
-    In case of error, `error' returns a non-empty error message.
-
-    `options' is an array of `struct Option' terminated by an element
-    containing a code which is zero. A null name means a short-only
-    option. A code value outside the unsigned char range means a
-    long-only option.
-
-    Arg_parser normally makes it appear as if all the option arguments
-    were specified before all the non-option arguments for the purposes
-    of parsing, even if the user of your program intermixed option and
-    non-option arguments. If you want the arguments in the exact order
-    the user typed them, call `Arg_parser' with `in_order' = true.
-
-    The argument `--' terminates all options; any following arguments are
-    treated as non-option arguments, even if they begin with a hyphen.
-
-    The syntax for optional option arguments is `-<short_option><argument>'
-    (without whitespace), or `--<long_option>=<argument>'.
