CLI Apps with Codeigniter?

Hi there!
I love CodeIgniter and it is often my first choice of framework.
But here is the thing: I want to create a powerful PHP-based static Site Generator.

I have a few options including Laravel Zero (Not the Laravel framework), Symfony Console component (not the framework), MiniCLI framework, or start from scratch.

But I have been wondering, CodeIgniter comes with the spark file and lets you generate commands that can be executed in the command line.

While that will serve the purpose, the issue is that I can't seem to find the way to set the application name/desc or the commands to show when running "php spark" in the command line.

Is there any way around it or should I skip the idea of using codeigniter for this one?
