//! Example of auth flow.
//!
//! To use this, set the environment variables `CLIENT_ID` and `CLIENT_SECRET` to their respective values.
//! See <https://dev.twitch.tv/docs/authentication#registration> for more information
//!
//! You'll need to add `http://localhost:10666/twitch/token` to your redirect URIs. (You can also override the url with the first argument passed to the executable)
