Tugboat

What is Tugboat?

Tugboat is a Spyglass plugin to generate airship-seaworthy site manifest files from an excel based engineering spec. The plugin is configured with an Excel sheet and its corresponding excel specification as inputs. Spyglass uses this plugin to construct an intermediary yaml which is processed further using J2 templates to generate site manifests.
