- * CRC-32 version 2.0.0 by Craig Bruce, 2006-04-29.
- *
- * This program generates the CRC-32 values for the files named in the
- * command-line arguments. These are the same CRC-32 values used by GZIP,
- * PKZIP, and ZMODEM. The Crc32_ComputeBuf() can also be detached and
- * used independently.
- *
- * THIS PROGRAM IS PUBLIC-DOMAIN SOFTWARE.
- *
- * Based on the byte-oriented implementation "File Verification Using CRC"
- * by Mark R. Nelson in Dr. Dobb's Journal, May 1992, pp. 64-67.
- *
- * v1.0.0: original release.
- * v1.0.1: fixed printf formats.
- * v1.0.2: fixed something else.
- * v1.0.3: replaced CRC constant table by generator function.
- * v1.0.4: reformatted code, made ANSI C. 1994-12-05.
- * v2.0.0: rewrote to use memory buffer & static table, 2006-04-29.

- * NAME:
- * Crc32_ComputeBuf() - computes the CRC-32 value of a memory buffer
- * DESCRIPTION:
