    Metadata details:
    filename: cloud_files.rb
    path of file: ./repos/travis.rb/lib/travis/cli/setup
    
    the code of the file until where you have to start completion: # frozen_string_
    
        def run
          deploy 'cloudfiles' do |config|
            config['username'] = ask('Rackspace Username: ').to_s
            config['api_key'] = ask('Rackspace Api Key: ') { |q| q.echo = '*' }.to_s
            config['region'] = ask('Cloud Files Region: ').to_s
            config['container'] = ask('Container: ').to_s
          end
