This clarifies the intent: the project is licenced under terms of LGPL version 3 only, but the standard headers cover only "3 or later", so we had to rewrite them. In the same step, we removed author information from individual files in favor of "SatoshiLabs and contributors", and include an AUTHORS file that lists the contributors. Apologies to those whose names are missing; please contact us if you wish to add your info to the AUTHORS file.
