# Maybe soon to be a feeds plugin. So you go like

#   generates_feed do

# I admit this is somewhat nutty, but I needed to find a way for mini_feed 
# (http://github.com/juliocesar/mini_feed/tree/master) to be able to access 
# helpers, or more specifically, link_to, so feeds can have links in them.
# This is what I came up with

# for instance

class Book < ActiveRecord::Base

// Oh, by the way, it works like this:
