Simple SVN client for browsing repositories and making small changes - nothing fancy and works for me
No integrated diff/merge tool, it's very inconvenient; No changelist support.
The program asks you to use the terminal for som tasks, so why to install a GUI if you will need to use the terminal...Personally I think it sucks.
SmartSVN is better. The foundation version is free, but isn't in the repos and requires the Java runtime www.syntevo.com/smartsvn
Not perfect but imho better than SVN workbench or the nautilus scripts. Tortoise might be the only app I miss from windows.
