I noticed that in the environment TheIde menu SVN and there is some functionality. I enjoyed RapidSVN. Nobody knows whether compatible SVN tags of these two systems, stored in a folder .svn?
Well, I know for sure that TortoiseSVN is compatible with SlikSVN command-line - I am using TheIDE/usvn most of time (because it is really convenient, fully automated - unlike Tortoise. And integrated.), but when I need any advanced function missing in usvn, I use Tortoise (on the same working copy).
