+ (description "This package was initially based on the pure go BLAKE2b
+implementation of Dmitry Chestnykh and merged with the (cgo dependent) AVX
+optimized BLAKE2 implementation (which in turn is based on the official
+implementation. It does so by using Go's Assembler for amd64 architectures
+with a golang only fallback for other architectures.
+
+In addition to AVX there is also support for AVX2 as well as SSE. Best
+performance is obtained with AVX2 which gives roughly a 4X performance
+increase approaching hashing speeds of 1GB/sec on a single core.")
