 423 <div class="paragraph"><p>You can use it as a human-readable bundle replacement (see

 443 <p>
 444         Specify how to handle signed tags.  Since any transformation
 445         after the export can change the tag names (which can also happen
 446         when excluding revisions) the signatures will not match.
 447 </p>
 448 <div class="paragraph"><p>When asking to <em>abort</em> (which is the default), this program will die
 449 when encountering a signed tag.  With <em>strip</em>, the tags will be made
 450 unsigned, with <em>verbatim</em>, they will be silently exported

 459         Since revisions and files to export can be limited by path,
 460         tagged objects may be filtered completely.
 461 </p>
 462 <div class="paragraph"><p>When asking to <em>abort</em> (which is the default), this program will die
 463 when encountering such a tag.  With <em>drop</em> it will omit such tags from

 488         Dumps the internal marks table to &lt;file&gt; when complete.
 489         Marks are written one per line as <tt>:markid SHA-1</tt>. Only marks
 490         for revisions are dumped; marks for blobs are ignored.
 491         Backends can use this file to validate imports after they
 492         have been completed, or to save the marks table across
 493         incremental runs.  As &lt;file&gt; is only opened and truncated
 494         at completion, the same path can also be safely given to
 495         --import-marks.

 516 <p>
 517         Some old repositories have tags without a tagger.  The
 518         fast-import protocol was pretty strict about that, and did not
 519         allow that.  So fake a tagger to be able to fast-import the

 528         Skip output of blob objects and instead refer to blobs via
 529         their original SHA-1 hash.  This is useful when rewriting the
 530         directory structure or history of a repository without
 531         touching the contents of individual files.  Note that the
 532         resulting stream can only be used by a repository which
 533         already contains the necessary objects.

 543         in the commit (as opposed to just listing the files which are
