# download current package indexes to data/<series>{,-proposed}/ for running
# britney against a PPA. The PPA will play the role of "-proposed" (i. e.
# "unstable" in britney terms, containing the updated packages to test), the
# Ubuntu archive has the "-release" part (i. e. "testing" in britney terms, in
# which the -proposed packages are being landed).
