EDIT: Don't forget to edit the first line to point to your local python 3! It's just python on Arch, python3 on Ubuntu and apparently python3.2 on Debian. Probably similar on most other distros.

I release this code in the public domain, or - where not applicable - under a CC0 license.

Turns out, I didn't read the pandoc manual very carefully... now updated & much better ;)

Thanks timo for some significant improvements on the code!
