//  Independent implementation of MD5 (RFC 1321).
// 
//   This code implements the MD5 Algorithm defined in RFC 1321, whose
//   text is available at http://www.ietf.org/rfc/rfc1321.txt
// 	  
//   The code is derived from the text of the RFC, including the test suite
//   (section A.5) but excluding the rest of Appendix A.  It does not include
//   any code or documentation that is identified in the RFC as being
//   copyrighted.
// 
//   The original and principal author of md5.h is L. Peter Deutsch
//   <ghost@aladdin.com>.  Other authors are noted in the change history
//   that follows (in reverse chronological order):
// 
//   2002-04-13 lpd Removed support for non-ANSI compilers; removed
// 	references to Ghostscript; clarified derivation from RFC 1321;
// 	now handles byte order either statically or dynamically.
//   1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
//   1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
// 	added conditionalization for C++ compilation from Martin
// 	Purschke <purschke@bnl.gov>.
//   1999-05-03 lpd Original version.

// This package supports both compile-time and run-time determination of CPU
// byte order.  If ARCH_IS_BIG_ENDIAN is defined as 0, the code will be
// compiled to run only on little-endian CPUs; if ARCH_IS_BIG_ENDIAN is
// defined as non-zero, the code will be compiled to run only on big-endian
// CPUs; if ARCH_IS_BIG_ENDIAN is not defined, the code will be compiled to
// run on either big- or little-endian CPUs, but will run slightly less
// efficiently on either one than if ARCH_IS_BIG_ENDIAN is defined.
