par2cmdline 0.8.1 File verification and repair tools

Par2cmdline uses Reed-Solomon error-correcting codes to generate and verify PAR2 recovery files. These files can be distributed alongside the source files or stored together with back-ups to protect against transmission errors or bit rot, the degradation of storage media over time. Unlike a simple checksum, PAR2 doesn't merely detect errors: as long as the damage isn't too extensive (and smaller than the size of the recovery file), it can even repair them.
