The tar that comes with my RedHat installation, and the gnu-tar I
compiled on the Suns at school don't have this option.  Instead, I
have this defined in my .bashrc

btar() { tar --use-compress-prog=bzip2 $* }

This requires any further options (such as xvf) to be prefaced with a -
Thus, the command on my machine is

btar -xvf file.tar.bz2
