This is an example Heroku buildpack.

Example usage:

$ ls
hello.txt

$ heroku create --stack cedar --buildpack http://github.com/heroku/heroku-buildpack-hello.git

$ git push heroku master
...
-----> Heroku receiving push
-----> Fetching custom buildpack
-----> HelloFramework app detected
-----> Found a hello.txt

The buildpack will detect that your app has a hello.txt in the root. If this file has contents, it will be copied to goodbye.txt with instances of the world hello changed to goodbye.

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.

For example, you can change the displayed name of the buildpack to GoodbyeFramework. Open bin/detect in your editor, and change HelloFramework to GoodbyeFramework.

Commit and push the changes to your buildpack to your Github fork, then push your sample app to Heroku to test. You should see:

-----> GoodbyeFramework app detected
