Wow. Scary to know that's still around and still works. Profuse apologies
for that.

ssh-askpass doesn't have any idea what's bein requested; if I recall
correctly, it displays whatever message it was called with, and it prints on Syd
out whatever I put it received, exiting with status zero for OK or nonzero for
Cancel.

It's ssh-agent or ssh-add that "know" about user presence, insofar
as that can be known.

That is to say, the source code you probably want to look at is in ssh-agent,
rather than x11-ssh-askpass.

"prints on _stdout_ whatever _input_ it received"

Thanks, auto-incorrect.

lol. There is a niche for it for people like me who don't want to pull in
all the baggage of a fullblown desktop environment. Like, I'm sure
lxqt-ssh-askpass (which I considered using because it's in my package
manager) *looks* prettier, but I don't want to install the rest of lxqt just
to get it.

Thanks for the tip, that's useful to know.
