Please update the CVS/SVN project info meta-data about your project
using the portal (http://portal.eclipse.org/).
The weekly CVS/SVN activity monitor batch job has detected the following
errors in the meta-data, some of which are related to your project.
The project page activity graph, the active/inactive committer list,
the commits explorer, and other similar pages are all driven by this
meta-data.  Incorrect meta-data causes incorrectly low activity to be
reported for your project. Get credit for the hard work you are doing:
update your project's meta-data today.

P.S. The committer activity data is incrementally updated over a seven day
period, so it might be a few days before your changes become visible.
