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::Erb#run method generates the CloudFormation templates
# and embeds user-data script into the template.
