     # To use Paperclip with S3, include the +aws-sdk+ gem in your Gemfile:
-    #   gem 'aws-sdk'
+    #   gem 'aws-sdk', '~> 1.6'
     # There are a few S3-specific options for has_attached_file:

     #   gives you. You can 'environment-space' this just like you do to your
     #   database.yml file, so different environments can use different accounts:
