Cool! It'd be great if the tool could be extended to handle Markdown in
addition to AsciiDoc. I prefer AsciiDoc because it has more solid
support for advanced features like tables, but Markdown is more popular.

The tool:

1. Runs `asciidoctor` to turn AsciiDoc into HTML.
2. Uses (chibi html-parser) to turn the HTML into SXML.
3. Does tree transforms to remove asciidoctor boilerplate from the SXML.
4. Uses (chibi sxml) to turn that SXML back into HTML.
5. Runs `tidy` to normalize the HTML and writes it into a .html file.

So the parts before the tree transforms could be done using commonmark
if the source filename ends in ".md" instead of ".adoc".

What is the tree transform library you are using in cuibap? I
hand-rolled my own transformation primitives for this program. It'd be
great to have a portable transformer lib in Snow.
