       #  NOTE FOR UPGRADING FROM PRE-3.0 VERSION       #
       ##################################################
       Paperclip 3.0 introduces a non-backward compatible change in your attachment
       path. This will help to prevent attachment name clashes when you have
       multiple attachments with the same name. If you didn't alter your
       attachment's path and are using Paperclip's default, you'll have to add
       `:path` and `:url` to your `has_attached_file` definition. For example:
       has_attached_file :avatar,
       :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
       \     :url => "/system/:attachment/:id/:style/:filename"
       Cleaning up the bundler cache.

We're not upgrading from Paperclip 2, so it's fine.
