title: Upload to Google Drive without any UI?
body: <p>I am looking to write a server application to upload files to Google Drive. I was previously using the Documents List API, but I see that is deprecated. I'd like to move to the Google Drive API, but that seems very restricted to using a web/OAuth flow.</p>
  
  <p>All I need to do is upload Word, Excel files etc. to Google Drive, but I need to do this in an entirely automated manner, with no user interface of any kind. I wish to write a command line application, which can run on cron or whatever, and not require human intervention via the web etc.</p>
  
  <p>I'd rather move away from Documents List API, as I don't want to get burned when they eventually turn it off, I'd like to use a supported API which Google are not going get rid of any time soon. Does this exist?</p>
