README
ActsAsNestedSet
==============
This acts_as extension provides Nested Set functionality. Nested Set is similiar to Tree, but with the added feature
that you can select the children and all of their descendents with a single query. A good use case for this is a
threaded post system, where you want to display every reply to a comment without multiple selects.
Example
=======
class Product < ActiveRecord::Base
acts_as_nested_set
