+The following control commands are supported:
+.TP
+.B h
+Print a list of all the commands understood. This list includes
+undocumented commands which mess with innduct's internal state and
+should only be used by a developer in conjuction with the innduct
+source code.
+.TP
+.B flush
+Start a new feed file and trigger a flush of the feed. (Or, cause
+the
+.I FLUSH-FINISH-PERIOD
+to expire early, forcibly completing a previously started flush.)
+.TP
+.B stop
+Log statistics and exit. (Same effect as SIGTERM or SIGINT.)
+.TP
+.BR "dump q" | a
+Writes information about innduct's state to a plain text file
+.IR feedfile \fB_dump\fR.
+This overwrites any previous dump.
+.B "dump q"
+is a summary including general state and a list of connections;
+.B "dump a"
+also includes information about each article innduct is dealing with.
+.TP
+.B next blscan
+Requests that innduct rescan for new backlog files at the next
+.I PERIOD
+poll. Normally innduct assumes that any backlog files dropped in by
+the administrator are not urgent and may not get around to noticing
+them for
+.IR BACKLOG-SCAN-PERIOD .
+.TP
+.B next conn
+Resets the connection startup delay counter so that innduct may
+consider making a new connection to the peer right away, regardless
+of the setting of
+.IR RECONNECT-PERIOD .
+A connection attempt will still only be made if innduct feels that it
+needs one, and innduct may wait up to
+.I PERIOD
+before actually starting the attempt.
