Bug#655185: RFP: pxz -- parallel xz compressor

Package: wnpp
Severity: wishlist

  Description     : Parallel LZMA/XZ compressor

Parallel XZ is a compression utility that takes advantage of running
LZMA compression of different parts of an input file on multiple cores
and processors simultaneously. Its primary goal is to utilize all
resources to speed up compression time with minimal possible influence
on compression ratio.

There seems to be a second independent parallel xz implementation with
BSD-style licensing at https://github.com/vasi/pixz/.

The main difference seems to be that it adds indexing for easier partial
decompression. But the fact that the tarballs from the examples sport a
.tpxz suffix suggests that the file format generated by pixz is not
compatible to xz (as it would be with pxz as far as I can see).
