+The simplest approach is to
+commit them with pristine-tar(1), e.g.
+
+=over 4
+
+ % pristine-tar commit ../foo_1.2.3.orig.tar.xz upstream/1.2.3
+
+=back
+
+and be sure to push the pristine-tar branch.
+If you are using git-buildpackage(1), just pass
+I<--git-pristine-tar> and I<--git-pristine-tar-commit>.
+
+Alternatively,
+the sponsee can put them on a suitable webserver,
+or attach to the e-mail,
+if they are small.
