+This talk uses `patat`, https://github.com/jaspervdj/patat which is a markdown
+based presentation tool that supports images on some terminals (like MacOS'
+iTerm2) and supports running code during the presentation to generate output,
+which is used here to display the listings of stacker.yaml examples that are
+kept separate to allow building them with the included makefile.
