module LocalizableModel

  #
  # Extends ActiveRecord::Base with the localizable setup method.
  #
  module ActiveRecordExtension
    # Extends the model with Localizable features.
    # It takes an optional block as argument, which yields an instance of
    # LocalizableModel::Configuration.
    #
    # Example:
    #
    #  class Page < ActiveRecord::Base
    #    localizable do
    #      attribute :name
    #      attribute :body
    #    end
    #  end
    #
