Comparison of Verson Control Systems (VSS, CVS, SVN)

I have prepared a comparison of Visual SourceSafe (VSS), CVS and Subversion with weighted scores to each. This kind of comparison helped me in convincing my project team to use Subversion and then later in moving other projects in a previous company to Subversion.

I am publishing this comparison so as to help others facing similar problem. If it helps you, please write a comment/email to me.
