  use Multigiri::HTML5::Forms
  use Multigiri::HTML5::Hidden
  use Multigiri::EmailObfuscator
  use Multigiri::GoogleAnalytics, :my_tracking_code
end

# RSS / Atom feeds processing
use Multigiri::XML, content_types: ["application/rss+xml", "application/atom+xml"] do
  # TODO
end

# Generic XML processing
use Multigiri::XML, content_types: [/\/xml$/] do
