+The following files have been written by Andrew Moon and have been

+* ed25519.c
+* modm-donna-32bit.h

+However, their git history shows that they were written by Andrew Moon
+as well; the initial check-in has public domain headers for all files
+(git commit a98e950f).  Newer files lack a similar header, but it seems
+the author didn't realise that that adding them would be required
+(see https://github.com/floodyberry/ed25519-donna/issues/24);
+issue comment 24#issuecomment-82552250 in particular seems to suggest as
+much.  It is therefore assumed that they are intended to be placed in
+the public domain as well.
+
+curve25519-donna.h has been modified by Andrew Moon, based on the
+amd64-51-30k implementation by Daniel J. Bernstein, Niels Duif,
+Tanja Lange, Peter Schwabe, and Bo-Yin Yang.  The amd64-51-30k
+implementation is contained in SUPERCOP
+(<https://bench.cr.yp.to/supercop.html>);
+the amd64-51-30k is part of the Ed25519 software, which has been
+dedicated to the public domain by its authors
+(<https://ed25519.cr.yp.to/software.html>).
