+           This option may not be combined with any of the others. Instead of
+           outputting a modified fast-import stream, output only the author,
+           committer and tagger names as they are encountered one per line
+           without any timestamp information. This can be used to help build
+           an initial authors file.

+           Do note that the names are output as-is from the input stream
+           whereas this utility expects to match only the email portion when
+           given an authors file with the --authors-file option. This means
+           the name, non-email portion and surrounding < and > characters will
+           have to be removed from the output provided by this option.
+           Additionally, of course, duplicate names need to be removed as
