    # Implementation:
    #
    # Review process:
    #   only check the command nodes to see if there is bundler namespace in config/deploy.rb file,
    #
    #   if the message of command node is "namespace" and the first argument  is "bundler",
    #   then it should use bundler's capistrano recipe.
