This came up on reddit: if you want to open a notebook or a file in the
text editor from the terminal inside the notebook web interface, you can
construct a URL to open. But to do that accurately, you need to know the
root directory where the server is looking, and the first part of the
URL. This exposes both of those as environment variables:
$JUPYTER_SERVER_ROOT and $JUPYTER_SERVER_URL.
