"""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.

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

NOTE this file is vastly out of sync with troggle/_deploy/wsl/localsettings.py
which is the most recent version used in active maintenance. There should be
essential differences, but there and many, many non-essential differences which 
should be eliminated for clarity and to use modern idioms. 8 March 2023.
