    -------------------------------
    
    ==> Welcome to libreevent!


    ==> You are running Version V1.0.0

Below you can see all important things that happen during operation.
libreevent logs all errors in the console such that they appear in the
log files when running it with an output pipe (which you should definitely do)

To do this run the following command when starting libreevent:
'node app.js > libreevent_log.txt'

` );

const settings = JSON.parse( fs.readFileSync( path.join( __dirname + '/config/settings.config.json' ) ) );

// Vue SSR and gets its support files (e.g. CSS and JS files) from 
// the /home/supportFiles/:file route plus its assets from the /otherAssets/:file
// route).
if ( settings.setupDone ) {
    app.get( '/', ( req, res ) => {
