Capistrano deployment email notifier for Rails 3

Do you need to send email notifications after application deployments?

Christopher Sexton developed a Simple Capistrano email notifier for rails. You can find details at http://www.codeography.com/2010/03/24/simple-capistrano-email-notifier-for-rails.html. 

Here is Rails 3 port of the notifier. 

The notifier sends an email after application deployment has been completed.
