Check with Marc, but I'm sure he'll be happy to get testers...

I think the man page is wrong. I had my problems with this as well...

Anyway, this is "old vgetty", which isn't maintained anymore. Marc's new
code will do it all differently, and (naturally...) a lot better.

I'm afraid I lost the source :(( -- but asking YaHoo or similar WWW search

Lots, since the internal structure of the "new and improved" vgetty will
be very different, I think. Marc?
