gtar isn't necessarily available. I know some of my boxes (not in the
buildfarm now, but they may be soon) don't have it.

"tar cf - files | gzip >foo.tar.gz" is likely to be much more portable. There's
probably a machine out there that only has compress, but...

On the other hand, 700k is a little less than 4 seconds on a T1 or about
45 seconds on the lowest of low end DSL lines. I always try and save
bandwidth, but if this looks like it'll be a problem it's not a big deal.
