- * Check collisions between options.
- *
- * The conflicts between options are described in ul_excl_t array. The
- * array contains groups of mutually exclusive options. For example
- *
- *	static const ul_excl_t excl[] = {
- *		{ 'Z','b','c' },		// first group
- *		{ 'b','x' },			// second group
- *		{ 0 }
- *	};
- *
- *	int excl_st[ARRAY_SIZE(excl)] = UL_EXCL_STATUS_INIT;
- *
- *	while ((c = getopt_long(argc, argv, "Zbcx", longopts, NULL)) != -1) {
- *
- *		err_exclusive_options(c, longopts, excl, excl_st);
- *
- *		switch (c) {
- *		case 'Z':
- *		   ....
- *		}
- *	}
- *
- * The array excl[] defines two groups of the mutually exclusive options. The
- * option '-b' is in the both groups.
- *
- * Note that the options in the group have to be in ASCII order (ABC..abc..) and
- * groups have to be also in ASCII order.
- *
- * The maximal number of the options in the group is 15 (size of the array is
- * 16, last is zero).
- *
- * The current status of options is stored in excl_st array. The size of the array
- * must be the same as number of the groups in the ul_excl_t array.
- *
- * If you're unsure then see sys-utils/mount.c or misc-utils/findmnt.c.
