title: Value of using Git with ClearCase, AccuRev or Perforce?
body: <p>I am interested in the value (or lack thereof) of using a traditional SCM product (ClearCase, AccuRev, Perforce, etc.) along with Git for large projects with distributed teams.</p>
  
  <p>Is there a significant value-add in terms of increased visibility into team activities? Control of branching and merging? Access control and security? Release engineering? Other factors? </p>
  
  <p>Or is it better to Git by itself? Or is there an open source SCM that would be equivalent to the commercial products mentioned above?</p>
  
  <p>Thanks.</p>
