crc 0.2

This is a general CRC (Cyclic Redundancy Check) generator for ruby. It is written by pure ruby with based on slice-by-eight algorithm (slice-by-16 algorithm as byte-order free and byte-alignment free). Included built-in CRC modules are CRC-32, CRC-64-XZ, CRC-64-ECMA, CRC-64-ISO, CRC-16-CCITT, CRC-16-IBM, CRC-8, CRC-5-USB, CRC-5-EPC and many more. Additional your customized CRC modules are defined to posible. If you need more speed, please use crc-turbo.
