module Lono
  # This class is not use by lono internally. It is really only meant to be
  # exposed to the lono userdata command so users can debug their generated
  # app/user_data scripts. It is useful for debugging.
  #
  # Normally, the Lono::DSL#run method generates the CloudFormation templates
  # and embeds user-data script into the template.
