If you need a hassle-free Windows solution, The "TAM TAM SVN SCC" plug-in works without a hitch. I downloaded it, and it self-installed. It shows up on the Preferences/Source Control option and accessed my Subversion host db without a hitch. It allows a free, apparently unlimited trial, but it's only $19.95 for a single-seat license.

I haven't used subversion before, so this might be an easy question for you. I just installed subversion and your script and it seems to work fine. But I get a "some_file is not a working copy" message if I want to check in some_file. What am I doing wrong?
PushOK is a Russian company, and the PushOK wrapper solution requires a "trial license", but the cost isn't stated. Some of us would like to have known this! I think the original question remains - how can we use the provided solution on Windows???
