This is a Heroku buildpack for Racket apps. It uses Racket.
Example usage:
$ ls
Procfile web.mkt heroku-setup.mkt
$ heroku create --stack cedar --buildpack http://github.com/onixie/heroku-buildpack-racket.git
$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack
-----> Racket Framework app detected
-----> Building Racket Runtime Environment
...
The buildpack will detect that your app has a heroku-setup.mkz in the root.
To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with --buildpack <your-github-url> and push to it.
