module AuthHelpers
  # The class responsable to send e-mails.
  #
  # It uses default views in the auth_helpers/views. If you want to customize
  # them, just do:
  #
  #   AuthHelpers::Notifier.template_root = "#{RAILS_ROOT}/app/views"
  #
  # And put your new views at: "RAILS_ROOT/app/views/auth_helpers/notifier/"
  #
  # You should also configure the sender and content_type:
  #
  #   AuthHelpers::Notifier.sender = %("José Valim" <jose.valim@gmail.com>)
  #   AuthHelpers::Notifier.content_type = 'text/html'
  #
  class Notifier < ActionMailer::Base
