Hi all!

Currently its only possible to compress tar files with multiple cores
using this command:
tar cf myfile.tar.bz2 --use-compress-prog=pbzip2 dir_to_compress/

with the standard compresstools its possible to write that way shorter:
E.g. tar cjf myfile.tar.bz2 dir_to_compress/
But this does not use multiple cores.

It should be possible that a standard option to the shown command for
using multiple cores, say, the parallel versions (pgzip/pbzip2)

An alternative would be using the multithreaded versions as default and
use the single core apps as fallback.

Gest Regards

Georg
