 439         <em>git fast-import</em> during import.

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

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

 468 rewrite the tag to tag an ancestor commit (via parent rewriting; see

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

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

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