-// This file provides a few functions for hashing strings. All of them are
-// high-quality functions in the sense that they pass standard tests such
-// as Austin Appleby's SMHasher. They are also fast.
-//
-// For 64-bit x86 code, on short strings, we don't know of anything faster than
-// CityHash64 that is of comparable quality. We believe our nearest competitor
-// is Murmur3. For 64-bit x86 code, CityHash64 is an excellent choice for hash
-// tables and most other hashing (excluding cryptography).
-//
-// For 32-bit x86 code, we don't know of anything faster than CityHash32 that
-// is of comparable quality. We believe our nearest competitor is Murmur3A.
-// (On 64-bit CPUs, it is typically faster to use the other CityHash variants.)
-//
-// Functions in the CityHash family are not suitable for cryptography.
-//
-// Please see CityHash's README file for more details on our performance
-// measurements and so on.
-//
-// WARNING: This code has been only lightly tested on big-endian platforms!
-// It is known to work well on little-endian platforms that have a small penalty
-// for unaligned reads, such as current Intel and AMD moderate-to-high-end CPUs.
-// It should work on all 32-bit and 64-bit platforms that allow unaligned reads;
-// bug reports are welcome.
-//
-// By the way, for some hash functions, given strings a and b, the hash
-// of a+b is easily derived from the hashes of a and b. This property
-// doesn't hold for any hash functions in this file.
