This is the update server. By default, it will output files to:
/var/www/html/assets

Simply use comp.py and it will convert assets and pretty much handle everything
for you. Make sure that raw/ folder is consistent with the same rules which builtin
assets follow regarding paths.

This is a development tool for optimization and not required for your server.
It **only** works in Debian Buster and other systems similar to this one, like
Ubuntu 18.04.
You can use, eg. GitLab Pages to serve the files and make a 301 on main server, or
simply not use the tool at all.

The choice is yours.
