Initial releases by Jonathan Westhues in 2005-2007 were made under GPL
"either version 2 of the License, or (at your option) any later version"
Since then, a number of dependencies and files were integrated to the project, but under a "GPLv3 or later" license. These components are reveng, desfire_crypto and lrpcrypto. Note that compnents cryptorf, hitag2crack and fpga-xc3s100e are also under GPLv3+ but not bound to the firmware or client source code.
Therefore, we must mechanically upgrade the license of the whole project to GPLv3+, as made possible by the initial licensing terms and as mandated by the inclusion of GPLv3+ code.
Still to do: update each source file header:
