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.

2002-03-11 lpd Corrected argument list for main(), and added int return

2002-02-21 lpd Added missing #include <stdio.h> in test program.

self-checking.

1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
