+/* Arg_parser reads the arguments in `argv' and creates a number of
+ option codes, option arguments and non-option arguments.
+
+ In case of error, `ap_error' returns a non-null pointer to an error
+ message.
+
+ `options' is an array of `struct ap_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 `ap_init' 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>'.
