Unable to authenticate using google-oauthlib-tool

I don't think --headless is documented as a supported flag. Where is this command sourced from?

--headless was removed in #264 because the OAuth feature it relied on (out-of-band) was turned down for security reasons.

I'm not aware of another general OAuth method to provide a headless experience like the one offered by --headless.
