*** 93,97 ****
  \begin{funcdesc}{crc32}{data\optional{, crc}}
  Compute CRC-32, the 32-bit checksum of data, starting with an initial
! crc.  This is consistent with the ZIP file checksum.  Use as follows:
  \begin{verbatim}
      print binascii.crc32("hello world")

  Compute CRC-32, the 32-bit checksum of data, starting with an initial
! crc.  This is consistent with the ZIP file checksum.  Since the
! algorithm is designed for use as a checksum algorithm, it is not
! suitable for use as a general hash algorithm.  Use as follows:
