GitHub Unsubscribe API

Manage your GitHub repository subscriptions from the command line. List organizations you're subscribed to, view repos within an organization, and bulk unsubscribe.

Why?

This script was created when I took a new job, and my notification settings inadvertently subscribed me to all 600+ of their repos. I wanted a better signal to noise ratio in my notifications, but I didn't want to click the "Unwatch All" button, which would remove my subscriptions to repos outside my new employer's org.
