# A minor modificiation of Michal Skalski's original Makefile version
# to only consider repos where no repo updates are in progress (as
# that may have us hanging quite a while otherwise). If no suitable
# local mirror can be found after four attempts, the default archive
# is returned instead.
# Some Ubuntu mirrors seem less reliable for this type of mirroring -
# as they are discoved they can be added to the blacklist below in order
# for them not to be considered.
