A colleague of mine agreed to using 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). Can anyone recommend me some? I'd really like to get version control going. Would be best if it had a GUI for merging files too, not just 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).
