Yes, it's still in beta and is available to MSDN subscribers only. There
are free "express" versions but they don't include source control
integration.
I will try the CVS proxy as I think (for other reasons) we will be using
CVS anyway. I tried Subversion first because it seemed to be the easier to
set up and import our SourceSafe database into.
Is there a tool you would recommend to import our SourceSafe database into
CVS, maintaining the file histories? I used vss2svn
(
http://vss2svn.tigris.org/) to move it to SVN with great results.
