"""Development server.
This server is intended for development only: it enables debugging tools,
and use a different port (5000) so it can more easily interface with other
applications.
Launching the server is relatively easy::
    $ py -3.9 -m venv env
    $ env\Scripts\activate
    $ pip install -r requirements.txt
    $ python dev.py
