History rewriting swiss army knife

  Hi,

  it is not very frequent, but sometimes you really want to rewrite your
history - you need to get rid of a copyright violation or a file with
confidential information slipped through, or who knows what other good
reason you might have. As long as you are aware of the implications of
all the tree/commit ids getting different, why not.

  It's never been so easy before - I've written cg-admin-rewritehist,
which will execute your filters for each commit (which can rewrite the
tree contents, just the tree itself through the index, committer/author
information and commit message) while the script will obviously preserve
all the other information like merges, author/committer information etc.
The script will place the rewritten history on a newly created branch.

  If you are interested, you can also look at the script at

	http://kernel.org/git/?p=cogito/cogito.git;a=blob;f=cg-admin-rewritehist

but it has few Cogito dependencies.

  Have fun,

I have forgotten this before.
