OK. This is the second message that suggests that and it is less
expensive than the 'try' approach. It also solves the problem to me.=20

Actually, I dunno. Probably not.

I've been doing that with other tools. I just wanted to know if I was
doing the right thing or the wrong thing... Everything is in separate
modules and the interface is a separate thing that can reuse the other
code, so this won't make me write more core (actually, I wouldn't
write the check for the X environment...).=20
