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
