+    //    the "(x - 1) ^ x" trick.
+    // 2. Because there is only signed comparison in SSE/AVX, we have to invert byte comparison results whenever signs of the corresponding
+    //    bytes are different. I.e. in signed comparison it's -1 < 1, but in unsigned it is the opposite (255 > 1). To do that we XOR left and right,
+    //    making the most significant bit of each byte 1 if the signs are different, and later apply this mask with another XOR to the comparison results.

+// seed_rng models a UniformRandomNumberGenerator (see Boost.Random).
+// Random number generators are hard to seed well.  This is intended to provide
+// good seed values for random number generators.
+// It creates random numbers from a sha1 hash of data from a variary of sources,
+// all of which are standard function calls.  It produces random numbers slowly.
+// Peter Dimov provided the details of sha1_random_digest_().

+
+// Revision History
+//  06 Feb 2006 - Initial Revision
+//  09 Nov 2006 - fixed variant and version bits for v4 guids
+//  13 Nov 2006 - added serialization
+//  17 Nov 2006 - added name-based guid creation
+//  20 Nov 2006 - add fixes for gcc (from Tim Blechmann)
+//  07 Mar 2007 - converted to header only
+//  10 May 2007 - removed need for Boost.Thread
+//              - added better seed - thanks Peter Dimov
+//              - removed null()
+//              - replaced byte_count() and output_bytes() with size() and begin() and end()
+//  11 May 2007 - fixed guid(ByteInputIterator first, ByteInputIterator last)
+//              - optimized operator>>
+//  14 May 2007 - converted from guid to uuid
+//  29 May 2007 - uses new implementation of sha1
+//  01 Jun 2007 - removed using namespace directives
+//  09 Nov 2007 - moved implementation to uuid.ipp file
+//  12 Nov 2007 - moved serialize code to uuid_serialize.hpp file
+//  25 Feb 2008 - moved to namespace boost::uuids
+//  19 Mar 2009 - changed to a POD, reorganized files
+//  28 Nov 2009 - disabled deprecated warnings for MSVC
+//  30 Nov 2009 - used BOOST_STATIC_CONSTANT
+//  02 Dec 2009 - removed BOOST_STATIC_CONSTANT - not all compilers like it
+//  29 Apr 2013 - added support for noexcept and constexpr, added optimizations for SSE/AVX
