-*  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 compute_crc32() 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:
-*     compute_crc32() - computes the CRC-32 value of a memory buffer
-*  DESCRIPTION:
-*     Computes or accumulates the CRC-32 value for a memory buffer.
-*     The 'in_crc32' gives a previously accumulated CRC-32 value to allow
-*     a CRC to be generated for multiple sequential buffer-fuls of data.
-*     The 'in_crc32' for the first buffer must be zero.
-*  ARGUMENTS:
-*     in_crc32 - accumulated CRC-32 value, must be 0 on first call
-*     buf     - buffer to compute CRC-32 value for
-*     buf_len  - number of bytes in buffer
-*  RETURNS:
-*     crc32 - computed CRC-32 value
-*  ERRORS:
-*     (no errors are possible)
