How to delete a Project created in RRC 3.0.1

I want to delete test project Area created in RRC 3.0.1 . Can we delete a Project Area created in RRC 3.0.1?? If yes please give me the steps to do so.

In RRC, you don't actually delete projects - you archive them.
To do so, you use the Application Administration page as described here:

One other note, since the project is archived and not deleted, you can not use that project name again. You can get around this by simply renaming the project before archiving it.

This can make for larger than necessary dbs. There are no repotools commands to run against the db to remove the project? If not, Are there any plans for it?
