# The following can then be used as apt sources:
# 	deb http://apt.dockerproject.org/repo $distro-$release $version
#
# For example:
#	deb http://apt.dockerproject.org/repo ubuntu-trusty main
#	deb http://apt.dockerproject.org/repo ubuntu-trusty testing
#	deb http://apt.dockerproject.org/repo debian-wheezy experimental
#	deb http://apt.dockerproject.org/repo debian-jessie main
#
# ... and so on and so forth for the builds created by hack/make/build-deb
