# -A specifies to build arch-all packages (non-arch dependent) in addition to
# binary packages
#
# -s specifies the resultant .changes should also include a rebuilt source package
#
# --force-orig-source means the .changes will have a .orig.tar.* with it, which
# otherwise we might omit. We need the orig source when including in our
# repository even though dpkg-buildpackage might think otherwise, because the
# original version of the package was usually not included in our repository.
#
# We always build for amd64. There is no 32-bit.
