There is apparently a cross-platform GUI toolkit now based, I believe
on GTK. I've not tried it yet, as I'm not to the point I'm ready to
mess with GUI's with Ada (I've only done GUI programming on the Mac).

BTW, Linux is good for some things, but in a lot of ways, it's not much
better than MS Windows (though as I type this I am burning a set of
Red Hat CD's). Personally I think the best use for Linux is cheap
semi-intelligent desktop terminals.

PULSE. The development was apparently done on the VAX, and
cross-compiled for the PDP-11/23. The book in question is "PULSE: An
Ada-based Distributed Operating System".
