The quotation from -> http://www.repairfaq.org/filipg/LINK/F_crc_v3.html

"We have seen that CRC algorithms vary in:
    *Width of the poly (polynomial).
    *Value of the poly.
    *Initial value for the register.
    *Whether the bits of each byte are reflected before being
      processed.
    *Whether the final register value should be reversed (as in
      reflected versions).
    *Value to XOR with the final register value.
In order to be able to talk about particular CRC algorithms, we need to
able to define them more precisely."
