On first use, drivel will ask you to go to [https://apps.twitter.com/app/new](https://apps.twitter.com/app/new), register a new app and create an access token. Those values will be stored in HOME/.drivel/ for later use.
 
 drivel will automatically split large status messages and multiple files into separate tweets belonging to the same thread.
