+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")
+ # Or, in two pieces:
+ crc = binascii.crc32("hello")
+ crc = binascii.crc32(" world", crc)
+ print crc

\begin{excdesc}{Error}
Exception raised on errors. These are usually programming errors.
