Comment 2 for bug 1320600

I'll be happy to work on this feature. I've already delved through the code to track down the info for this report quite a bit, and it looks like I'll have create a search routine that would find both current-style saved news and new-style.

I'd actually like to implement the new tagging as a custom metadata field if possible, which would reduce the likelihood of a user accidentally making files unrecognizable to the cleanup routine.

Another idea I have is to tag files with a "delete if older than days" field, which would override the global setting and would be set from the recipe. (Though it'd be have to stored in the generated file in some way that add_news could get at it, since I don't want to force add_news to look at the recipe directly and break encapsulation.)
