Overview

Note:

the arity of #initialize and #execute! are extremely important for testing purposes. It is a requirement to perform in-process testing with Aruba. In process testing is much faster than spawning a new Ruby process for each test.

This is the main entry point for the CLI. It exposes the method #execute! to start the CLI.
