+=item git-debrebase convert-from-dgit-view [<convert-options>] [upstream]
+
+Converts any dgit-compatible git branch
+corresponding to a (possibly hypothetical) 3.0 quilt dsc source package
+into a git-debrebase-compatible branch.
+
+This operation should not be used
+if the branch is already in git-debrebase form.
+Normally git-debrebase will refuse to continue in this case
+(or silently do nothing if the global --noop-ok option is used).
+
+Some representation of the original upstream source code will be needed.
+If I<upstream> is supplied, that must be a suitable upstream commit.
+By default,
+git-debrebase will look first for git tags (as for new-upstream),
+and then for orig tarballs which it will ask dgit to process.
+
+The upstream source must be exactly right and
+all the patches in debian/patches must be up to date.
+Applying the patches from debian/patches to the upstream source
+must result in exactly your HEAD.
+
+The output is laundered and stitched.
+The resulting history is not particularly pretty,
+especially if orig tarball(s) were imported
+to produce a synthetic upstream commit.
+
+The available convert-options are as follows.
