Overview

The template [name] % tag block is used in conjunction with InlineTemplatesFileSystem to allow users to define custom templates within the context of the current Liquid template. Generally speaking, they will define their own templates in the “shared” markup content, which is prepended to the individual screen templates before rendering.
