-// Original design developed by Darin Adler based on classes developed by Mark
-// Borgerding. Four original class templates were combined into a single endian
-// class template by Beman Dawes, who also added the unrolled_byte_loops sign
-// partial specialization to correctly extend the sign when cover integer size
-// differs from endian representation size.
-
-// TODO: When a compiler supporting constexpr becomes available, try possible uses.
