+
+# All source code originated ab initio in this project, authored by and
+# copyright Nick Black, save the C++ wrappers in include/ncpp, which were
+# authored by and copyright Marek Habersack and Nick Black. This includes C
+# source files, C++ source files, Rust source files, Python source files, cpp
+# header files, CMake files, and all other source.
+#
+# All Debian packaging originated ab initio in this project, save components
+# generated by dh-make(1), were authored by and copyright Nick Black, with
+# assistance from Robert Edmonds.
+#
+# Data files as packaged in the DFSG tarball's data/ were created and copyright
+# Nick Black. Images were built up in the GIMP (in one case using a photograph
+# taken and copyright Nick Black). Videos were created in OpenShot. The former's
+# XCF and the latter's OSP sources have been included in the source package, but
+# are not installed into binary packages. This allows the multimedia to be
+# modified and rebuilt, but does not require this lengthy and brittle (due to
+# tool version changes) step as part of the typical build nor installation.
