Note that gump has already been disabled.
Heads up sent to the cactus-user@ mailing list.
JIRA read only. DOAP file updated. SVN read-only and notification pointed to the attic.
Added to Attic website. User list added as one under the Attic's purview to be removed later (basically leave time for any questions).
Website to do.
Only item I know isn't done is putting a note in the downloads header.html. There isn't currently one, and I don't think it works in archives.apache anyway.
I have however removed the downloads from the mirror sync directory.
