Xcode Project Scheme sharing... how to do that?

When I commit my Xcode project to SVN, I found that the schemes that I created are saved under my username folder, e.g.

abc.xcodeproj/xcuserdata/_my_user_name_.xcuserdatad/xcschemes/projectABC_debug.xcscheme

When multiple users are working on the same project, the schemes can't be shared to them since they don't have the same user name.

So, how to share the schemes among multiple users easily?
