Replace Pandoc with Markdown
Pandoc was too fiddly for me, so I've replaced it with Markdown
for more straightforward Markdown-to-HTML conversion.

A few months ago I lost the source files I used to generate my static website. Fortunately there was no irreparable data loss because I still had the generated site up on my server. The problem was now I needed to write a script that would extract all the articles into source files again, and then I'd have to reconfigure the site generator. Then I went, "Oh. This is a Prolog problem." (But then I love Prolog so every problem is a Prolog problem but I don't care. Fight me.) A Prolog problem is basically a set of rules and the logic can be run in either direction. I figured if I could write a Prolog program that described my HTML template then I could use the same code both to un-generate and re-generate the website.
-So the skinny is I wound up writing my own static website generator in Prolog. Well, the main components are in Prolog. I also wrote a bash script to make use of a bunch of common \*nix utilities (find, sed, grep, etc.) and to pipe output to some third-party programs where I needed them (Smartypants, and it's still TBD but possibly Pandoc in the future). Weirdest bit was that I just couldn't find anything decent to generate RSS feeds. I considered dropping the RSS all together, but I've spent enough time haranguing people for not supporting interoperable standards that I didn't want to be a hypocrite. I wound up writing my own RSS generator too, also in Prolog.

It's pretty closely tailored to my specific needs, but it works, and IMHO it works better than my old site generator which injected a bunch of nonsense into my HTML. To make this work for your site, all you need to do is define the template of your website in "html.pl".
