  you can see an example script at

	http://repo.or.cz/w/elinks.git?a=blob;f=contrib/grafthistory.sh

and I have tried vainly few times to get a similar script to the kernel too

	http://lists.zerezo.com/linux-kernel/msg6599002.html

that can use both wget and curl and will also download tag refs for the history.

  The format of the grafts file itself (.git/info/grafts) is pretty
simple (just one-graft-per-line where you first say the commit id and
then the parent commit(s) to be drafted onto it), please see
Documentation/repository-layout.txt for details.
