splitting of a source package

[Patrice Dumas <pertusus free fr>]

Hello,

I would like to split the cernlib source package to match what is done 
in debian (debian is more or less the real upstream for cernlib, which 
is abandonned by the the CERN).

I don't think that there is a guidelines on that. Should I resubmit the
packages for a review? Or just add requests on
http://fedoraproject.org/wiki/Extras/CVSSyncNeeded

Last question, for the mclibs package which was once in the cernlib package
I think should do something like (assuming that cernlib-2005-22 is split):

Obsolete: cernlib < cernlib-2005-22

Is it wrong or right?
