reuniting the cache with a group?

[Robert Marshall]

Due to some problem with leafnode (or maybe a gnus/leafnode
interaction) I ended up with a lot of my subscribed groups
disappearing - not really sure what happened and
gnus-group-jump-to-group didn't complete on these groups despite them
being there on my local server.

I've mostly repaired the vanished groups but I use gnus-use-cache and
I've lost the ticked articles (not surprising really!), they're all
there in ~/News/cache/<group.name>, is there a way of getting that
information back into .newsrc.eld? The info refers to
gnus-cache-generate-nov-databases and gnus-cache-generate-active which
appears to be the other way I've not _yet_ found a way of putting back
the ticked articles into gnus - unless I'm missing something obvious?
