+	Marks are written one per line as `:markid SHA-1`. Only marks
+	for revisions are dumped; marks for blobs are ignored.
+	Backends can use this file to validate imports after they
+	have been completed, or to save the marks table across
+	incremental runs.  As <file> is only opened and truncated
+	at completion, the same path can also be safely given to
+	\--import-marks.

+--import-marks=<file>::
+	Before processing any input, load the marks specified in
+	<file>.  The input file must exist, must be readable, and
+	must use the same format as produced by \--export-marks.

+Any commits that have already been marked will not be exported again.
+If the backend uses a similar \--import-marks file, this allows for
+incremental bidirectional exporting of the repository by keeping the
+marks the same across runs.
