I couldn't get the stage tag to show up with a test multistage setup, do you have a sample on I could test with?

[arielo]

To use multistage add the following to the top of your deploy.rb

require 'bundler/capistrano'
require 'capistrano/ext/multistage'
set :stages, %w(production staging)
set :default_stage, 'staging'

Hey, sorry so slow on this. I've refactored the capistrano integration to support capistrano v3 so I can't cleanly merge your change, but I've incorporated it in the branch: #43
