help

Set the help for this option.

Although you can also pass the help string as an argument to option, this function can be more convenient for long help strings.

If you want to control the help string lazily or based on the context, you can pass a lambda that returns a string.

Example:

val number by option()
     .int()
     .help("This is an option that takes a number")

Set the help for this option lazily.

You have access to the current Context if you need the theme or other information.

Example:

val number by option()
     .int()
     .help { theme.info("This is an option that takes a number") }
