[Pulp-list] Exclude packages or package groups from repo sync

Any updates on this one?  I am also looking for a way to avoid syncing the
source RPMs from the Oracle Linux upstream repo, as Brian mentioned.

As a workaround, I tried removing the SRPMs from my repo following the sync
using " pulp-admin rpm repo remove srpm --repo-id=ol5-x86_64 -a 20130901",
but that had no effect (even though " pulp-admin rpm repo content srpm
--repo-id=ol5-x86_64 -a 20130901 " showed me the packages).
