ud3tn is available under multiple licenses and we want to reflect this in our source code. But which license information should appear first and how can we manage this efficiently in the future? The Linux Kernel uses SPDX expressions instead of boilerplate sections. This seems to be a great approach, so we do the same here. Signed-off-by: Georg Alexander Murzik <georg.murzik@d3tn.com>
