That's how I understand what Rob wrote, too.

I just tested it using exw.exe 2.5 alpha, in general it *does* work
on my system, and I don't see a reason why it shouldn't work on other
systems. However, I don't know whether there might be particular
"dynamic inclusion problems" that can't be solved that way.

Yes, that will probably work, too.
