[Zope] Re-add a disk-based product that was deleted

[Gregory Dudek]

  I have a disk based product that was not working. I manually deleted
it from the product management interface in the control panel folder.
  Now I have anew version that seems OK, but I can't persuade zope to
look in the Products folder and find the product again.  Help!
  Of course, I could undo the deleteion but then zope will get mixed
up between the old and new versions, I fear.
  Any ideas?

  Thanks, Greg
