This allows creating HTML presentations with `asciidoctor-revealjs presentation.adoc`. NOTE: The generated HTML file implicitly depend on reveal.js (and I see no good way to bundle it with Nix). Either provide reveal.js in a local path next to the generated HTML file[1], or override the revealjsdir attribute, for example by pointing to an URL (can also be a path): asciidoctor-revealjs -a revealjsdir=https://cdn.jsdelivr.net/npm/reveal.js@3.9.2 presentation.adoc Implementation details: 1. Added "gem 'asciidoctor-revealjs'" to the Gemfile. 2. Ran "nix-shell -p bundler --run 'bundle lock --update'" from pkgs/tools/typesetting/asciidoctor/. 3. Hand edited Gemfile.lock to remove all but the asciidoctor-revealjs changes. (Rationale: allow backporting to release-20.09.) 4. Finish off with "nix-shell -p bundix --run 'bundix'". [1] Of course Nix can help with _that_, but that's external to the asciidoctor-revealjs program. (cherry picked from commit 8f13d3c)
