+ "libb2 is a portable implementation of the BLAKE2 family of cryptographic
+hash functions. It includes optimised implementations for IA-32 and AMD64
+processors, and an interface layer that automatically selects the best
+implementation for the processor it is run on.
+
+@dfn{BLAKE2} (RFC 7693) is a family of high-speed cryptographic hash functions
+that are faster than MD5, SHA-1, SHA-2, and SHA-3, yet are at least as secure
+as the latest standard, SHA-3. It is an improved version of the SHA-3 finalist
+BLAKE.")
