      #
      #  1. --manpage-urls will allow you to use manual pages as they are defined in
      #  the nixpkgs documentation.
      #  2. --revision is the project revision as it is defined in 'release.json' in the
      #  repository root
      #  3. --script will inject a given Javascript file into the resulting pages inside
      #  the <script> tag.
      #  4. --toc-depth will determine the depth of the initial Table of Contents while
      #  --section-toc-depth will determine the depth of per-section Table of Contents
      #  sections.
