Using grafts file to rewrite history

Hi!

My googling powers have yet eluded to find me an answer to this:

Given an (unpublished) Git repository and a "grafts" file that slightly
re-orders commits, how do I reprocess this repository (using
git-filter-branch, probably) to have a true history according to the
"grafts" file?

I am trying to use git-import-tars to import non-linear development
history, and then use a grafts file to find the "proper" history. I
would like to re-order the history before i publish it in a public Git
repository.
