"""
A few examples of displaying a bottom toolbar.

The ``prompt`` function takes a ``bottom_toolbar`` attribute.
This can be any kind of formatted text (plain text, HTML or ANSI), or
it can be a callable that takes an App and returns an of these.

The bottom toolbar will always receive the style 'bottom-toolbar', and the text
inside will get 'bottom-toolbar.text'. These can be used to change the default
style.
