"""Settings for a troggle installation which may vary among different
installations: for development or deployment, in a docker image or
python virtual environment (venv), on ubuntu, debian or in Windows
System for Linux (WSL), on the main server or in the potato hut,
using SQLite or mariaDB.

It sets the directory locations for the major parts of the system so
that e.g. expofiles can be on a different filesystem, or /javascript/ can be in
a system-wide location rather than just a local directory.

This file is included at the end of the main troggle/settings.py file so that
it overwrites defaults in that file.
