+//  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.
