<<-LONG_DESC Given no arguments, restarts all servers for the application. Given an environment name, restarts only the servers for that environment, e.g. `restart webserver`. Use `-q` for worker environments to clarify which worker environment to restart, e.g. `restart worker -q default`. Requires AWS credentials to be set in the environment, i.e. AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY. LONG_DESC
