Is this project still maintained?

After my pull request #15 from Tyrben:feature/argument-parsing
That I need for future features (a directory depth control)
I didn't get any reaction.
I see the last changes are from 2016.
And that there is another PR without response.

I did the changes I need in my own fork.
I'm available to discuss, and if wanted, PR this new changes on the original project.
Best regards.
