+ARTICLE: "checksums.fnv1" "Fowler-Noll-Vo checksum"
+  "The Fowler-Noll-Vo checksum algorithm is another simple and fast checksum. It comes in 32, 64, 128, 256, 512 and 1024-bit versions, each in 1 and 1a variants. The 1a variants tend to produce a slightly better result. See http://en.wikipedia.org/wiki/Fowler_Noll_Vo_hash for more details."

+! I couldn't find any test vectors for 128, 256, 512, or 1024 versions of FNV1 hashes.
+! So, just to check that your maths works the same as my maths, here's a few samples computed on my laptop.
+! So they may be right or wrong, but either way, them failing is cause for concern somewhere...
