### A Simple Task

{% prism ruby %}
role :demo, %w{example.com example.org, example.net}
task :uptime do |host|
  on :demo, in: :parallel do
    uptime = capture(:uptime)
    puts "#{host.hostname} reports: #{uptime}"
  end
end
{% endprism %}

Capistrano extends the *Rake* DSL with methods specific to running commands
`on()` servers.

### For Any Language

Capistrano is written in Ruby, but it can easily be used to deploy any
language. Popular extensions add support for *Wordpress* blogs as well as
*Symfony* and *Node.js* applications.

If your language has special deployment requirements, Capistrano can easily be
extended to support them.
