Not sure about other Static Site Generators, but Eleventy lets you write your content in straight HTML, or whatever else you want, doesn't have to be in Markdown. Do that, plus don't use anything much else except simple template includes, and you've basically got the author's build script, without having to write or maintain any code yourself. Just sayin'.
