connecting existing local git repository to svn

Hi,

I'd like to create a branch in a subversion repository so that I can work with git-svn on it.

My git repository is already with a history, that I don't want to replicate to subversion, I want to start with subversion having just the latest revision and then continue from there normally (git svn dcommit/rebase).

How can I do that?

Thanks,

Ittay
