+=head3 Verifying upstream's tarball releases
+
+=over 4
+
+It can be a good idea to compare upstream's released tarballs with the
+release tags, at least for the first upload of the package. If they
+are different, you might need to add some additional steps to your
+I<debian/rules>, such as running autotools.
+
+A convenient way to perform this check is to import the tarball as
+described in the following section, using a different value for
+'upstream-tag', and then use git-diff(1) to compare the imported
+tarball to the release tag. If they are the same, you can use
+upstream's tarball instead of running git-archive(1).
