Well, i made a nice ProgressBar.py, and when it was done i did a cvs update
and saw dishi already made one recently. I feel stupid. Anyway, dishi's one
is a bit better and more flexible, but you never now if someone could somehow
make use of my version, if not it can still serve as an example why running
cvs update very day is a very good thing to do.

PS. I got a ProgressBox too, but that one isn't useless yet as it includes a
label, and ddishi's one doesn't. Maybe i'll update dishi's code that's
already in cvs.
