How do I SVN add all unversioned files to SVN?

I’m looking for a good way to automatically ‘svn add’ all unversioned files in a working copy to my SVN repository.

I have a live server that can create a few files that should be under source control. I would like to have a short script that I can run to automatically add these, instead of going through and adding them one at a time.

My server is running Windows Server 2003 so a Unix solution won’t work.
