%description
CRC RevEng is an arbitrary-precision CRC calculator and
algorithm finder. It calculates CRCs using any of the 72 preset
algorithms, or a user-specified algorithm to any width. It calculates
reversed CRCs to give the bit pattern that produces a desired forward
CRC. CRC RevEng also reverse-engineers any CRC algorithm from
sufficient correctly formatted message-CRC pairs and optional known
parameters. It comprises input interpretation options.
It is compliant with Ross Williams' Rocksoft model of parametrised CRC
algorithms.
