Overview

TODO:

extract conditions into individual objects.

The runner defines the command line interface for Lugg, using the other components and defining command line options and their implementations.

When creating a Runner object, you pass it your option flags (typically ARGV). You can then apply its conditions to an IO object (typically ARGF).
