SmartSVN is a feature-rich and easy-to-use Subversion client. It runs on Linux, Mac OS X, Unix, and Windows. In addition to the normal SVN commands like checkout, update, commit, merge, etc., it provides tag and branch handling (no need to deal with URLs just to switch to a different tag or branch), a built-in file compare and conflict solver, and much more. There is no need to install additional tools for handling SVN working copies, like a command line SVN client or a file comparison tool.
WANdisco's Subversion/CVS Access Control provides full authorization, authentication, access control, and audit capabilities that go well beyond what Subversion and CVS provide on their own. Administrators can implement and maintain the most complex security policies with a minimum of effort. Valuable intellectual property is protected and a complete audit trail is provided, insuring compliance with SOX and other regulatory requirements.
