title: restful-authentication 'Could not find generator authenticated'
body: <p>I just installed the restful-authentication plugin on Rails 3, using:
  rails plugin install git://github.com/technoweenie/restful-authentication.git</p>
  
  <p>To generate the authentication files, the tutorial stated I should execute:</p>
  
  <p>ruby script/generate authenticated user sessions --include-activation</p>
  
  <p>(which in rails3 is):</p>
  
  <p>rails g authenticated user sessions --include-activation</p>
  
  <p>However, when I execute this line, I get the following error:
  "Could not find generator authenticated."</p>
  
  <p>..Does anyone have any pointers on how to get past this? I may have also messed up the 'rails g' command i specified.</p>
  
  <p>Thanks.</p>
