These files come from the tarball present in the Debian archives [1]. The SHA-256 digest of the tarball, c5e0d23424e88525bfba0ecdf0a432a8d93c885d04740df06a9eeee44e5f25e4, matches the digest preserved in the FreeBSD ports tree [2], giving further confidence that these files are as distributed by upstream.
