- *
- * $Log: crc-mktab.c,v $
- * Revision 1.4  2001/03/10 10:59:21  mdw
- * Fix generating tables where the chunk size is longer than the
- * polynomial.  Also fix output formatting when there aren't enough entries
- * to fill a line.
- *
- * Revision 1.3  2001/01/20 12:06:01  mdw
- * Define flags with macros, to ensure unsignedness.
- *
- * Revision 1.2  2000/10/08 11:07:21  mdw
- * With no arguments, give an error rather than spewing a big table at the
- * user.
- *
- * Revision 1.1  2000/07/21 19:01:33  mdw
- * Generate the CRC table rather than hardcoding it.
