times. If `true`, all values will be collected in an array. If

`false`, values for the option are last-wins. **Default:** `false`.

* `short` {string} A single character alias for the option.

* `default` {string | boolean | string\[] | boolean\[]} The default value to

be used if (and only if) the option does not appear in the arguments to be

parsed. It must be of the same type as the `type` property. When `multiple`

is `true`, it must be an array.

* `default` {string | boolean | string\[] | boolean\[]} The value to assign to

the option if it does not appear in the arguments to be parsed. The value

must match the type specified by the `type` property. If `multiple` is

`true`, it must be an array. No default value is applied when the option

does appear in the arguments to be parsed, even if the provided value

is falsy.

* `strict` {boolean} Should an error be thrown when unknown arguments

are encountered, or when arguments are passed that do not match the

`type` configured in `options`.
