`OPT_COUNTUP(short, long, &int_var, description)`::
Introduce a count-up option.
- `int_var` is incremented on each use of `--option`, and
- reset to zero with `--no-option`.
+ Each use of `--option` increments `int_var`, starting from zero
+ (even if initially negative), and `--no-option` resets it to
+ zero. To determine if `--option` or `--no-option` was encountered at
+ all, initialize `int_var` to a negative value, and if it is still
+ negative after parse_options(), then neither `--option` nor
+ `--no-option` was seen.
`OPT_BIT(short, long, &int_var, description, mask)`::
Introduce a boolean option.
