+@code{nnagent} doesn't handle expiry. Instead, there's a special
+@code{gnus-agent-expiry} command that will expire all read articles that
+are older than @code{gnus-agent-expiry-days} days. It can be run
+whenever you feel that you're running out of space. It's not
+particularly fast or efficient, and it's not a particularly good idea to
+interrupt it (with @kbd{C-g} or anything else) once you've started it.
