svn - What Subversion clients for Windows are there that do not need installation?

Question

A colleague of mine agreed to using Subversion (SVN) for our little project, but only if he doesn't have to install it. He has a U3 USB stick where he keeps the project files and he would like the SVN client to live there as well. I tried searching for a non-installable SVN client, but couldn't find anything (although I suspect that many of the available clients would run if just copy-pasted from an installation folder). What can be recommended?

I'd really like to get version control going. It would be best if it had a GUI for merging files too, not just the command line.

Added: The copy-paste from an existing installation is one solution, but I'd like to see first if there perhaps isn't some client that does not require installation by design. If not, I guess RapidSVN is nice enough (although it does leave stuff in Windows registry).

Try RapidSVN. The CollabNet binaries can be used in a similar fashion for command-line support. Yes, these have installers, but you can simply copy the binaries around -- I use Universal Extractor to get the binaries out without having to run the installer.

Also, an enterprising user has packaged RapidSVN as a PortableApp. There is an "installer", but it really just unzips things into a directory of your choice and writes a default configuration file into that directory.
