Take the example of a rake task that pushes a deployment to Heroku along
with some S3 assets. Every developer has their own heroku application, and
they configure it by creating a Heroku remote origin.

To push to heroku a developer does do *git push heroku master*, then they
need to push some assets to their own S3 bucket (eg. developer-bucket). The
name of the bucket is configured as a S3_BUCKET variable on their heroku
application. Right now we execute 'heroku config --long', parse that to
figure out what the S3_BUCKET is, which is not ideal. Nowhere the Rake task
knows the name of the remote Heroku application.

Of course we could force every developer to hardcode the name of their
application somewhere on the client, but we might as well keep our heroku
config output parsing instead.

Makes sense?
