+/*  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>'.
