+#!/usr/bin/env python

+This works directly on the indices, rather than using the generic conversion
+logic. After conversion, it will have backed up your old indices to
+.bzr/repository/indices-gi. This is significantly faster than the generic 'bzr
+upgrade' but it does not work for all repository formats (only pack format
+repositories are supported).
