[cvsnt] Move HEAD to end of branch

[Ralf Steinhaeusser]

Hello,

is it possible to move the HEAD-Tag (is HEAD a tag?).

What happened: A project evolved, and at a time a branch was created to 
try some new technology. It turned out that this technology serves our 
needs better, so I would like to make this brach the new 
main-development path (-> HEAD) and the old head becomes a "dead end" 
branch.

Any way to to that?
Thanks,
Ralf
