/* 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.
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.
'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.
