+        Higher-Than (bitrate, integer):
+            Only reencode files with bitrates higher then <bitrate>kbps. This
+            only applies if sample-rate, channel count and of course format are
+            equal. If unset, only files with bitrates equal to that of the
+            target will be copied (actually, hardlinking will be attempted
+            first).
+
+            As Ogg Vorbis target quality is not defined by its bitrate, Ogg
+            Vorbis files will always be reencoded if unset.
