Re: Importing from tarballs; add, rm, update-index?

I did this with a large pile of tarballs, see

    http://blogs.gnome.org/view/mortenw/2007/01/07/0

for the script.

Bottom line: git is very, very good at compressing a pile of related tarballs.
In fact, about 10x better than gzip.

(Not really surprising, of course.)
