parchive - 1.1-4.1+b1 main

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-Soloman 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.
