Reload app served via gunicorn when specific files change

I like using 💚🦄 gunicorn to serve Flask apps, like httpcat.us. The Web site will be reloaded when app.py is modified with --reload. If I want to also reload the Web service when various HTML, CSS and JavaScript files are changed, I can use --reload-extra-file. In the end, it looks something like:

gunicorn --reload --reload-extra-file static/dist/css/output.css \ --reload-extra-file templates/index.html --reload-extra-file static/js/popups.js \ -b 127.0.0.1:8088 --log-level debug 'app:app'

Logs don't go to the console by default.

BTW: gunicorn is 🟩 green 🦄 unicorn. The pronunciation is ambiguous.
