Hugo page bundles are a useful way to organize content.
To create a reveal-hugo presentation from the index.md file of a leaf page bundle, you need to specify the layout manually.
layout = "bundle"
Why? By default, reveal-hugo doesn’t create pages for single template types (foo.md), only for list template types (_index.md).
This technique can also be used to output an HTML file for any section of a presentation, should you need to.
If more markdown files are present in the bundle, their contents will be added to the presentation.
Specify weight in the frontmatter if it’s necessary to order them.
If you don’t want them to be included, specify layout = "list" in the front matter instead of layout = "bundle".
