Does gzip compression really give us so little as to only save 0.3 MB
over uncompressed for so many packages?  I figured the difference
would be a bit more - does it suck for compressing binary data?
Should we consider moving to a different, more compressed archive
format?  Or am I just making a mountain out of a molehill here?
