Getting apt-get to download Packages.bz2 instead of Packages.gz

[Micha Feigin <michf@post.tau.ac.il>]

Is it possible to do that? All I found was a flame full tread that the only
sugestion it contained didn't work:

Default
{
	Packages::Compress ". bzip2"
}

still downloads the 3MB Packages.gz instead of the 2MB Packages.bz2

Thanks
