    #
    #  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.
