-# This module dynamically pulls amazon content into Koha. It does not
-# store the data in Koha's database. You'll need to get a developer's key
-# as well as an associate's tag to use it.
-# FIXME: need to write up more docs.
-#
-# To use this module you need to do three things:
-# 1. get a dev key and associate tag from Amazon
-# 2. uncomment the Amazon stuff in opac-detail.pl
-# 3. add the template variables to opac-detail.tmpl
-# here's what's available:
-# ProductDescription
-# ImageUrlMedium
-# ListPrice
-# url
-# loop SimilarProducts (Product)
-# loop Reviews (rating, Summary)
