+*
+* 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.

+* NAME:

+* 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)
