Since Rails 3.0, generators are built on top of "Thor":http://github.com/wycats/thor. Thor has a powerful options parsing and a great API for manipulating files. For instance, let's build a generator that creates an initializer file named +initializer.rb+ inside +config/initializers+.

+h3. Adding Generators Fallbacks
One last feature about generators which is quite useful for plugin generators is fallbacks. For example, imagine that you want to add a feature on top of TestUnit test framework, like "shoulda":http://github.com/thoughtbot/shoulda does. Since TestUnit already implements all generators required by Rails and shoulda just want to overwrite part of it, there is no need for shoulda to reimplement some generators again, they can simply tell Rails to use a +TestUnit+ generator if none was found under +Shoulda+ namespace.
