		Define argument flags.

		The key is the flag name and the value is an object with any of:

		- `type`: Type of value. (Possible values: `string` `boolean` `number`)
		- `alias`: Usually used to define a short flag alias.
		- `default`: Default value when the flag is not specified.
		- `isRequired`: Determine if the flag is required.
			If it's only known at runtime whether the flag is required or not you can pass a Function instead of a boolean, which based on the given flags and other non-flag arguments should decide if the flag is required.
		- `isMultiple`: Indicates a flag can be set multiple times. Values are turned into an array. (Default: false)
			Multiple values are provided by specifying the flag multiple times, for example, `$ foo -u rainbow -u cat`. Space- or comma-separated values are *not* supported.

		@example
		```
		flags: {
			unicorn: {
				type: 'string',
				alias: 'u',
				default: ['rainbow', 'cat'],
				isMultiple: true,
				isRequired: (flags, input) => {
					if (flags.otherFlag) {
						return true;
					}

					return false;
