title: No Cedar supported app detected error in Sinatra Heroku app
body: <p>Seems like everything worked fine when I pushed to Heroku as shown below. Then I run into an error on the latter while following Heroku's Docs: <a href="http://devcenter.heroku.com/articles/ruby#install_the_heroku_commandline_client" rel="nofollow">http://devcenter.heroku.com/articles/ruby#install_the_heroku_commandline_client</a></p>

  <p>With heroku.logs I get:</p>

  <p>How is there no Cedar-support detected when the Gemfile and Procfile are both in there?
  Also, nothing appears on the heroku webpage.</p>
