Kensa is now deprecated in favor of the addons-admin Heroku CLI plugin.
Kensa is a command-line utility to help Heroku add-on providers integrating their services to Heroku. It offers commands to create and validate manifests, and to run the same API calls Heroku runs on your service to provision and deprovision resources.
Install it like any Ruby Gem:
$ gem install kensa
Refer to the Heroku Add-ons Resource Center for more information on usage, and how to build your Heroku add-on:
