Dear all, at the "Spring" Hepix conference in Karlsruhe, we had complaints that SL wasn't "scientific" enough, i.e. was missing several packages. I had contacted several developers to see whether they could make +maintain SL versions (RPM+SRPM). Examples where there was some willingness are OpenScientist and GSL, with ROOT and GEANT4 at least not against the idea. I also have some things I prepared myself (xmgrace or (eventually) a recompilable CERNLIB), which currently would go into the CERN repository but are useful outside. The question is where to store these - I don't want such things to become "CERN"-additions, but to be available to the wider community. We could put them into the CERN "extras" repository and then mirror (I think Connie already takes things from there), but I think some specific section on scientificlinux.org would be more appropriate (including instructions for package authors). ?
