Show HN: Mapdown creates a sitemap for your Markdown files

I have a handful of websites built, automatically, from Markdown files. I don't always link to those on the site but I do want them to show up in search engines. So, I built Mapdown to generate the sitemap.xml file for me.

I built this and wrote the documentation in a few hours but I think it's fairly complete. Still, I haven't spent a lot of time tuning it. I've already started to use it on my own sites.

What do you think?
