+     *  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.
+     *  v2.1.0: modified by Nico, 2013-04-20
