       String::CRC32 - Perl interface for cyclic redundency check generation


           use String::CRC32;

           $crc = crc32("some string");
           $crc = crc32("some string", initvalue);

           $somestring = "some string";
           $crc = crc32($somestring);

           open(SOMEFILE, "location/of/some.file");
           binmode SOMEFILE;
           $crc = crc32(*SOMEFILE);


       The CRC32 module calculates CRC sums of 32 bit lenghts.  It generates the same CRC values
       as ZMODEM, PKZIP, PICCHECK and many others.

       Despite its name, this module is able to compute the checksum of files as well as strings.


           $crc = crc32("some string");

         results in the same as

           $crc = crc32(" string", crc32("some"));

       This is useful for subsequent CRC checking of substrings.

       You may even check files:

           open(SOMEFILE, "location/of/some.file");
           binmode SOMEFILE;
           $crc = crc32(*SOMEFILE);

       A init value may also been supplied in the above example.

       CRC algorithm code taken from CRC-32 by Craig Bruce.  The module stuff is inspired by a
       similar perl module called String::CRC by David Sharnoff & Matthew Dillon.  Horst
       Fickenscher told me that it could be useful to supply an init value to the crc checking
       function and so I included this possibility.
