+Set the copyright holder in the output.  Translators are expected to transfer
+the copyright for their translations, so that package maintainers can
+distribute them without legal risk.  If @var{string} is empty, the output
+files are marked as being in the public domain; in this case, the translators

+The default value for @var{string} is the Free Software Foundation, Inc.
+This is recommended also for packages outside the GNU project, because the
