EPEL – Fedora Project Wiki
EPEL is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs like CentOS or Scientific Linux.
About time, and thank you redhat/fedora, want fedora extra packages in centos, then install this epel-release .rpm frickin’ sweet !
