Yum-presto is in Extras! Woo-hoo! I just wanted to say thank you Tim,
for a very detailed review, Rex for pointing out some obvious things
that needed attention, and Kevin for sponsoring me!
x86_64 is now being mirrored, but I've run across a bug in deltarpm.
Apparently it doesn't know how to deal with two packages with the exact
same name, epoch, version and release, but different arches. So when
you do a yum update, it only is able to use the deltarpm for one of the
two packages (even though both are available).
Also, I found a small bug in 0.3.7 that mainly affects x86_64, so I've
pushed 0.3.8. It should show up in Extras tomorrow.
