Error occurred while calculating annotation data.
Log Message:	Tidy up of files. These are all old things that are not only no longer used but are also probably useless to anyone other than us. This saves checking them out all the time, and makes the "cms/source" tree contain only current stuff. They'll still exist in the attic's though :)
