The par2 Portfile 55643 2009-08-16 05:25:21Z jmr macports.org $

PortSystem 1.0

Name: par2
Version: 0.4
Revision: 2
Description: Parchive: Parity Archive Volume Set for data recovery

Long Description: Parchive takes .par files and can regenerate missing data based upon a Reed-Soloman Code. This is useful for restoring missing pieces of a multi-part archive like the kinds used on Usenet. Version 2 does not require like-sized pieces, so it is useful for many more kinds of data recovery.

--->  Extracting par2
--->  Configuring par2
--->  Building par2 with target all

--->  Staging par2 into destroot

--->  Installing par2
