Is yum considered to be a GUI application? Anyway, an aspect of
yum which may be helpful to look at is that when used with presto, it
never tells you how much it is going to really download. What I mean is
that it says Total download size: 110 M (say), but that amount is not
accounting for presto which will reduce the haul to much less. I think
that it would be more helpful to have a(nother) note saying how much it
will download. What good is it to have a note after the event that says
that presto reduced the download to 6% or whatever. Makes it look like
department store receipts that nowadays suggest that you "saved" xx% on
a sale item....
