rpm.livna.org, a repository of add-on RPM packages for Fedora as well as RHEL (version 5 and later) and its compatible derivates like CentOS.
In 2008 rpm.livna.org merged with two other package repositories into RPM Fusion. All packages have been moved there except one that RPM Fusion for various reasons didn't want to take.
