In SL it reads: "> ... we have added several packages to Scientific Linux that are not found anywhere in the upstream release, including IceWM, OpenAFS, " In Centos it reads: "CentOS Extras - This repository contains items that provide additional functionality to CentOS ... horde framework and packages, freenx, apt, XFCE, and yumex" What is right though, in SL these extra packages exist in the default repo, not in an extra repo - but it is enabled by default in Centos. info from here: http://wiki.centos.org/AdditionalResources/Repositories Rainer
