    # Set up the Heroku scheduler to run this command every hour. See example setup at https://goo.gl/nMCSH3
    #
    # Requires env vars to be set in Heroku with `heroku config:set`:
    # - HEROKU_APP_NAME: this is just the app name in Heroku, i.e. `heroku apps` will list all apps you have access to
    # - HEROKU_CLI_USER: Once Heroku CLI is authenticated (https://goo.gl/Qypr4x), check `cat .netrc` (or `_netrc` on Windows),
    # look for `login` under `machine api.heroku.com`
    # - HEROKU_CLI_TOKEN: As above, but use the `password` field
    #
    # It helps if this file has execute privileges `chmod +x restart.sh`

    # Test this script works by running `heroku run "~/restart.sh"`
