Nonsense. I used ClearCase briefly a while ago, and I had no problem
maintaining two workspaces with different versions.

I quote from the ClearCase website (http://www-01.ibm.com/software/awdtools/clearcase/features/index.html?S_CMP=rnav):

    Fast, immediate access to virtually any version of a file   

You can of course impose your own policy on your use of the tool. But
ClearCase out of the box does what I want, not what you say it does.

Now you are talking about file version locking to prevent conflicts. I
was talking about project version checkout. Two very different things.

Which means you need different versions for different customers; exactly
what I am saying.

Hmm, you are going to say "no, not versions, just configurations of many
small projects". I still don't believe it. If one customer is using a
configuration that was frozen 5 years ago, clearly that will involve
different _versions_ than a customer just starting today.

The point is that _I_ dictate the requirements, and find tools that meet
them. I don't let tools dictate to me (which is why I like Emacs better
than GPS, to bring this vaguely back on topic :).
