-        This command frees repository space by compacting segments.
-
-        Use this regularly to avoid running out of space - you do not need to use this
-        after each borg command though. It is especially useful after deleting archives,
-        because only compaction will really free repository space.
-
-        borg compact does not need a key, so it is possible to invoke it from the
-        client or also from the server.
-
-        Depending on the amount of segments that need compaction, it may take a while,
-        so consider using the ``--progress`` option.
-
-        A segment is compacted if the amount of saved space is above the percentage value
-        given by the ``--threshold`` option. If omitted, a threshold of 10% is used.
-        When using ``--verbose``, borg will output an estimate of the freed space.
