this applies to **a lot** of other video documentation material, from
application user guides to presentations

the same holds for GUI interaction (when a GUI video-doc is needed); I'm
not an expert in GUI "scripting" but I guess something like xdotool
script executed in a "classical" screencast application could do the job
(maybe https://github.com/rprichard/x11-canvas-screencast is
interesting, too)

this would be simply great :-)

if I had money to invest I would _pay_ for such an automation system

great, simply *great*: thank you for sharing this useful ideas!
