Use server-side includes (with Apache XBitHack setting) in web. This means that we can have one main web page, dottes.html, for each book and include the intro and tunelist to make the page. This removes the separate header and footer components. Perhaps we should use a template engine instead to generate the output. That means choosing one. And preferably one that isn't aimed only at HTML so we could use it for the printed books. More research required.
