- *  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:
- *     Computes or accumulates the CRC-32 value for a memory buffer.
- *     The 'inCrc32' gives a previously accumulated CRC-32 value to allow
- *     a CRC to be generated for multiple sequential buffer-fuls of data.
- *     The 'inCrc32' for the first buffer must be zero.
- *  ARGUMENTS:
- *     inCrc32 - accumulated CRC-32 value, must be 0 on first call
- *     buf     - buffer to compute CRC-32 value for
- *     bufLen  - number of bytes in buffer
- *  RETURNS:
- *     crc32 - computed CRC-32 value
- *  ERRORS:
- *     (no errors are possible)

-*  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)

+ *  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.

+ *  DESCRIPTION:
+ *     Computes or accumulates the CRC-32 value for a memory buffer.
+ *     The 'inCrc32' gives a previously accumulated CRC-32 value to allow
+ *     a CRC to be generated for multiple sequential buffer-fuls of data.
+ *     The 'inCrc32' for the first buffer must be zero.
+ *  ARGUMENTS:
+ *     inCrc32 - accumulated CRC-32 value, must be 0 on first call
+ *     buf     - buffer to compute CRC-32 value for
+ *     bufLen  - number of bytes in buffer
+ *  RETURNS:
+ *     crc32 - computed CRC-32 value
+ *  ERRORS:
+ *     (no errors are possible)
