title: Why ./script/generate model X does not generate spec/models/X_spec.rb
body: <p>I'm on Rails 2.3.2 + Rspec 1.3.2...On other projects, I noticed that when I do ./script/generate model X, it would create spec files for me instead of test unit files.  But for some reason it's not...</p>
  
  <p>I have Rspec installed properly as it can be ran and what not.  I know you can do ./script/generate rspec_model X, but still, I remember being able to replace test unit outright.</p>
  
  <p>Any ideas?  Thanks!</p>
