+\fB\-\-sort=\fIORDER\fR
+When creating an archive, sort directory entries according to
+\fIORDER\fR, which is one of
+.BR none ,
+.BR name ", or"
+.BR inode .
+
+The default is \fB\-\-sort=none\fR, which stores archive members in
+the same order as returned by the operating system.
+
+Using \fB\-\-sort=name\fR ensures the member ordering in the created archive
+is uniform and reproducible.
+
+Using \fB\-\-sort=inode\fR reduces the number of disk seeks made when
+creating the archive and thus can considerably speed up archivation.
+This sorting order is supported only if the underlying system provides
+the necessary information.
