Subclipse export best practice?

I am a cfeclipse/Tortoise SVN user and find that the ability to export only the differences between 2 revisions is extremely productive. This allows me to easily copy just the changed files into production. I'd like to switch over to using subversion for various reasons, but I cannot find any documentation anywhere that subversion will allow this. To the best of my knowledge, subversion will only export what you select form the working copy. Can anyone confirm this in subclipse? If subclipse cannot export differences, how are you all exporting your changes for transfer to a production site? Thanks, Terry Schmitt
