As I’ve mentioned previously, this site is built statically with the excellent Jekyll. If you’re a fellow Jekyll user, you might find this interesting.
I wrote a plugin to allow splitting posts across multiple pages, for example for lengthy articles, reviews with sections, or even stories with chapters.
You can find the code on github.
The plugin’s functionality is extremely customisable - take a look at the README file for more details.
I hope it’ll be useful to you.
