xdotool and xautomation are two command line X11 automation tools. I've used the former for a while and only recently found out about the existence of the latter, and I'm curious to know what someone who used both for a while has to say about them. In particular:
Do they have the same intended usage? It seems so from the man pages but I could be missing some detail.
Are they equally supported in most systems? Or is one more widely used than the other?
Are there things that can be done with one but not the other?
