awesome_nested_set

Hi,

I've been trying to setup a threaded comments system all weekend using
various plugins and I'm now trying to use awesome_nested_set (http://
github.com/collectiveidea/awesome_nested_set/tree/master) which seems
to be the most up-to-date nested plugin for Rails.

Unfortunately there is very little documentation around for this
plugin and it's too complex for my brain.

I've got my models set up as follows (stripped down):

class Post < ActiveRecord::Base
  has_many :comments
end

class Comment < ActiveRecord::Base
  acts_as_nested_set
  belongs_to :user
end

Now what I want to do is get all the comments for a Post in *one*
query and I then want to display the Comments as a multi-level
unordered list (possibly using a helper which yields to a block?).

Can anyone help me out?

Thanks
