I am looking for a recommended link to download a Tortoise equivalent for OpenSUSE with GNOME desktop.
I've tried a few in the past, and not found anything as good as TortoiseSVN. But that was a while ago--probably 3 years ago. More recently, I've just used the command-line.
But when I originally looked, I eventually settled on RapidSVN. Not as good as TortoiseSVN but not too bad. There's also PySVN Workbench, part of the PySVN project. These don't integrate nicely with the Gnome file manager, however, like TortoiseSVN does with Explorer.
A while ago, I also looked at NautilusSVN, which looked promising albeit immature. Now that has turned into RabitVCS, and it aims to support multiple VCS including Subversion.
