.TH PARCHIVE "1" "May 30 2004" "parchive 1.1" "User Commands"
.SH NAME
parchive \- RAID like data recovery for PAR ver 1.0 files
.SH DESCRIPTION
The idea behind the parchive is to provide a tool to apply the data-recovery
capability concepts of RAID-like systems to the posting and recovery of
multi-part archives on Usenet. Current filespec and clients support the
'Reed-Soloman Code' implementation that allows for recovery of any 'X'
volumes for 'X' parity volumes present.

The key to this mission is a clean file format specification which provides
all the necessary capabilities for programs to easily verify and regenerate
single missing parts out of a set of archives.

We might just be able to make binary posting and downloading on Usenet a
little easier. That's a pretty cool goal!

Note that parchive supports the old legacy version 1.0 PAR format.
For new projects, use the par2 package which supports the version 2.0 
PAR format which provides superior features.

This manual page was written for the Debian GNU/Linux distribution
because the original program does not have a manual page.
