parchive 1.1-5 (arm64 binary) in ubuntu noble

 This utility applies the data-recovery capability concepts of RAID-like
 systems to the posting and downloading of multi-part archives on USENET by
 providing the ability to create and use redundant recovery records. It
 supports the 'Reed-Solomon Code' implementation that allows for recovery of
 any 'X' volumes for 'X' parity volumes present. It is popularly used on
 USENET postings, but is not limited to this use.
