+.B logfile-only on | off
+Specify that debug messages should only go to the configured logfile, and
+not to stderr.
+.TP
+.B logfile-rotate <max> <Mbytes> <hours>
+Specify automatic rotation for the configured logfile as the maximum
+number of old logfiles to retain, a maximum size in megabytes to allow a
+logfile to grow before rotation, and a maximum age in hours for a logfile
+to be used before rotation. The maximum number must be in the range 1-99.
+Setting Mbytes or hours to zero disables the size or age check, respectively.
+At least one of Mbytes or hours must be non-zero. By default no automatic
+rotation will be performed.
