Rails 3 Application Templates do not work

I wanted to create an example Rails 3 template file for the bug-mash, so I started with the following, just to see where the template code was:

    # in test_template.rb

raise 'foo'</code>

I then ran that with rake rails:template LOCATION=test_template.rb --trace. I got

no such file to load -- generators

So I delved into railties/lib/rails/tasks/framework.rake and changed require 'generators' to require 'rails/generators' in the :template task. Now I get

uninitialized constant Rails::Generators::App

I looked in railties/lib/rails/generators and found nothing relevant. What happened to the application generators?
