How can I move my SVN working copy to Codeplex, maintainting file properties, but not history?

I am about to open-source one of my projects, and I want to move the current instance of it into CodePlex.

How would I go about copying the current working directory i开发者_Python百科nto CodePlex's SVN, maintainting pile properties (like "svn:needs-lock" and "svn:mime-type"), without maintaining history?

I don't want or need the history moved, I will continue to archive the history of the project on my own. I just don't want to have to manually set "svn:needs-lock" on all of my binary files again.
