+``@command{screen} for X11'': it allows you to run programs, usually on a
+remote host, direct their display to your local machine, and then to
+disconnect from these programs and reconnect from the same or another machine,
+without losing any state.  It can also be used to forward full desktops from
+X11 servers, Windows, or macOS.")
