It’s one file per chapter, although for this test I merged them.

Sure, of course this is probably more of a benchmark test, as I try
to avoid edge cases.

Here are the pages: <>

I left out the build script, as that just wraps the output in ERb
templates, creates Table of Contents etc. which IMO is not useful for
testing Markdown converters themselves. The markdown.references is
the shared reference list for the chapters, so that should be
appended to whatever file is converted.
