+  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):
+
+  2007-12-24 Changed to C++ and adapted to OpenTTD source
+  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.
