 \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")

 \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. 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:
