But looking at the quickstart, you typically don't subclass Bottle, you require it, and call run()? So your typical bottle app won't be a subclass of bottle? At which point you can't make an instance of it, to pass to mount()?

Looking at the documentation for mount() it looks like you should be able to mount the quick-start app - but it's not clear of you create an instance to pass to mount?

That is if I have example.py:

  from bottle import route, run, template

  @route('/hello/<name>')
  def index(name):
    return template('<b>Hello {{name}}</b>!', name=name)

  run(host='localhost', port=8080)

    test.py
    =======
    import bottle
    
    @bottle.get('/')
    def index():
        return 'INDEX'
    
    # a new wsgi app
    hello = bottle.Bottle()
    
    @hello.get('/<name>')
    def greet(name):
        return 'Hello, ' + name
    
    bottle.app().mount('/hello', hello)

You should have 2 working routes, "/" and "/hello/<name>".

But I'm still not clear on how I require "example.py" and mount it (ie how do I make an wsgi instance from a python file that is a bottle app)?
