Thanks to Jeffrey Kishner, I now have a script in Fargo that exports a Fargo top level node and its child nodes as a plain HTML document. The top level node is the document title, with a corresponding H1, and all the rest of the content are paragraphs with any associated HTML for links and images.

The original source exported the items as an unordered list, but it was pretty straight forward to edit it to put in paragraph tags rather than list item tags.
