   configure [options] [source] [target]               gets environment variables from Vault and uploads them to the current app
   deploy-static [options] <source> [otherSources...]  Deploys static <source> to S3.  Requires AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY env vars
   run [options]                                       Runs the local app through the router
-  rebuild [options] [apps...]                         DEPRECATED. Trigger a rebuild of the latest master on Circle
   gtg [app]                                           Runs gtg checks for an app
   review-app [options] [appName]                      Create or find an existing heroku review app and print out the app name. [appName] is the package.json name (which is also the value of VAULT_NAME). On the first build of a branch, Heroku will create a review app with a build. On subsequent builds, Heroku will automatically generate a new build, which this task looks for. See https://devcenter.heroku.com/articles/review-apps-beta for more details of the internals
   upload-assets-to-s3 [options]                       Uploads a folder of assets to an S3 bucket
