packages no longer in core page

[Patrice Dumas <pertusus free fr>]

Hello,

I am currently doing a script (in fact, modifying Christian script) 
to output automatically info like the one listed at 
http://fedoraproject.org/wiki/Extras/OrphanedPackagesFC4
for fedora core releases since fc 1.

I can currently output the list of the srpm that aren't in core 
development nor in extra development, but I need additional information
to eliminate the packages that have been obsoleted or merged into 
other packages, for which it wouldn't make sense to have a package in 
extras (like, for example redhat-config-network. Thus I need some info 
like what is on 
http://fedoraproject.org/wiki/Extras/PackagesNoLongerInDevel

Does it seems worth, and what should I do next?
