+I have split the initial [[https://orgmode.org/][Org-mode]] setup over thirteen listings.  Here, follows a
 list detailing and motivating each listing:
 1. Listing [[lst:set-org-options]] handles basic [[https://orgmode.org/][Org-mode]] options.
 2. Listing [[lst:org-capture-templates]] initializes a simple capture template.
 3. Listing [[lst:setup-org-babel]] sets ~ob-core~, ~ob-latex~, and ~ob-lisp~ options.
    See [[info:org#Working with Source Code][working with source code (info)]] for Org Babel information.

    block values with [[https://github.com/psf/black#readme][black]] instead of [[https://docs.python.org/3/library/pprint.html][pprint]].  This snippet may break in the
    future, because it sets =org-babel-python--def-format-value= which is a
    constant declared "private" by two dashes in its name!
