Can someone provide an example of an optional argument?

How would one go about adding optional arguments.

package platform.args

import com.xenomachina.argparser.ArgParser

class ArgsProcess(parser: ArgParser) {

    val data by parser.storing("-s", "--settings",
            help = "path to the settings file")

    val version by parser.flagging("-v", "--version",
            help="Prints out the version of the program")
}

My program is currently crashing out if I don't specify the settings file. Sorry, I have read the read me but I might have missed this or misunderstood. It looks as though you do support optional arguments, but I don't understand how they are declared as such.

Nevermind, it was a problem with my IDE. It was not importing this line:

import com.xenomachina.argparser.default
