Documentation

If non-nil, Gnus will keep read articles for later re-retrieval.

If it is a number N, then Gnus will only keep the last N articles read. If it is neither nil nor a number, Gnus will keep all read articles. This is not a good idea.

Probably introduced at or before Emacs version 19.32.
