The CGI source and content for libot.eu.org. Assumes you're using
systemd-networkd and a virtual ethernet adapter for LiBot (I use
systemd-machined for that but you can probably use others). Include
nginx.conf in your setup and make sure to set $network_interface (to
the virtual ethernet adapter's name in networkd) and $network_host
(to LiBot's IP) to set up.
