title: Missing script/generate in Rails 3
body: <p>I just installed Rails 3 and created my first app.  The install of Rails3 + ruby 1.9 went very smoothly but I am missing the generate script in script/generate.</p>
  
  <p>I have created a new app from scratch with no options to verify.</p>
  
  <p>Any idea why this is happening and how to fix it?</p>
