What you do is create a message of type signal and then just send it
out. There should be no destination field in this case.

spec and then rapidly decided that was a bad approach. I don't remember
if I even implemented it.

Look at the PNG/SVG diagram on the web site, perhaps.

Sorry this is a bit hard to figure out, but you're dealing with pre-1.0
software. The eventual idea will be a nice simple tutorial using the
GLib bindings, but not much point writing it until the API is more
