yum-presto-0.6.2-1.fc13.noarch

Yum-presto is a plugin for yum that looks for deltarpms rather than rpms whenever they are available. This has the potential of saving a lot of bandwidth when downloading updates.

A Deltarpm is the difference between two rpms. If you already have foo-1.0 installed and foo-1.1 is available, yum-presto will download the deltarpm for foo-1.0 => 1.1 rather than the full foo-1.1 rpm, and then build the full foo-1.1 package from your installed foo-1.0 and the downloaded deltarpm.
