Generate HTML from a Folder of Markdown Files

I have some Markdown files that I’m editing and I wanted to generate a folder of HTML files. I looked around on my machine and was surprised I didn’t have anything at hand for that already.

So I wrote a script. I’m a Ruby novice, and it’s quite likely that my Ruby is weird in a dozen different ways. But the script still might be useful to you. (The script requires the RDiscount gem.)
