-//
-// 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 64-bit x86 code, on long strings, the picture is more complicated.
-// On many recent Intel CPUs, such as Nehalem, Westmere, Sandy Bridge, etc.,
-// CityHashCrc128 appears to be faster than all competitors of comparable
-// quality.  CityHash128 is also good but not quite as fast.  We believe our
-// nearest competitor is Bob Jenkins' Spooky.  We don't have great data for
-// other 64-bit CPUs, but for long strings we know that Spooky is slightly
-// faster than CityHash on some relatively recent AMD x86-64 CPUs, for example.
-// Note that CityHashCrc128 is declared in citycrc.h.
-//
-// 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.
