-  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.
