%description
This project collects a few CRC32C implementations under an umbrella that
dispatches to a suitable implementation based on the host computer's hardware
capabilities. CRC32C is specified as the CRC that uses the iSCSI polynomial in
RFC 3720. The polynomial was introduced by G. Castagnoli, S. Braeuer and M.
Herrmann. CRC32C is used in software such as Btrfs, ext4, Ceph and leveldb.
