[;1m  crc32(Data)[0m

  Computes and returns the crc32 (IEEE 802.3 style) checksum for [;;4m[0m
  [;;4mData[0m.

[;1m  crc32(OldCrc, Data)[0m

  Continues computing the crc32 checksum by combining the previous
  checksum, [;;4mOldCrc[0m, with the checksum of [;;4mData[0m.

  The following code:

    X = erlang:crc32(Data1),
    Y = erlang:crc32(X,Data2).

  assigns the same value to [;;4mY[0m as this:

    Y = erlang:crc32([Data1,Data2]).
