Overview

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.
