Ask HN: Minimal static site builder?

I have very basic needs. Just want to make a couple clean-looking webpages.

There are hundreds of static site generators that all require dozens of dependencies. But all I need are some flat-files or a minimal command-line app to help. Then I’ll fill in some HTML the old-fashioned way, or maybe write something up in Markdown and have it magically look nice in HTML. (I can play with the styles, I don’t care about that aspect. I just want it to have a clean structure.)

Any suggestions?
