vertical space. Scrolling up and down should be avoided since it is very jarring
for people who attend the class.
You can test the amount of space available using a simple tool. Uncomment these
lines in the `book.toml` file to have a red rectangle rendered on top of all
pages:
```toml
[preprocessor.aspect-ratio-helper]
command = "./aspect-ratio-helper.py"
```
You can test the amount of space available using a simple tool. This tool can be
used by clicking a toggle button next to the search button on left side of the
navbar.
The rectangle has an aspect ratio similar to what you can see when you share
your screen on a 16:9 display or projector.

"""mdbook preprocessor which will help show the presentation aspect ratio.
The preprocessor adds a large red rectangle on every page. The
rectangle has an aspect ratio of 16 to 8.5, meaning that it is
slightly smaller than a standard 16/9 monitor.
The idea is that this approximates what the course participants can
see at once during a class. This in turn will help you estimate when
the slides are too large to be seen without scrolling.
Enable it in book.toml.
