Updating obr with latest release of prefs service

[Sahoo]

Hi,

The process as documented in [1] to update obr is not clear to me. How 
do I actually update repository.xml with released artifacts? Do I 
checkout from the svn tag and run the maven command? It does not sound 
correct, since it will lead to regeneration of artifacts. Ideally I 
would like repository.xml to be updated with artifacts that are uploaded 
to remote repository.

Thanks,
Sahoo
