+Update 2015-05-21 on the nature of the original DXPC license: The
+original DXPC code used to be available under a license which failed to
+explicitly grant the permission to modify, but was later retroactively
+re-licensed under the 2-clause BSD license (see
+README.on-retroactive-DXPC-license for the copyright owners' statements;
+see <https://bugs.debian.org/784565> for more details).
+
+In the course of discussion, it also became evident that Gian Filippo
+Pinzari never participated in any of the official DXPC releases, but
+rather worked on the forked code on the NoMachine side. Thus, we
+crossed-out his name in the above copyright notice and moved him to the
+top list of copyright holders associated with the GPL-2 re-licensing done
+by NoMachine.
+Thus, the version of DXPC where NXCOMP got forked from (most likely some
+DXPC version between release 3.7.0 and release 3.8.0) can be considered
+as BSD-2-clause, as quoted below:
