I came to the conclusion that layer:nginx and layer:lets-encrypt should
each do one thing well for better reuse. layer:lets-encrypt no longer
includes layer:nginx, but they're easy to use together.

layer:lets-encrypt now just obtains certs, which you can then use in nginx
templates -- or in any web application configuration, really. See the
latest README[1] for up-to-date usage.
