Root of hierachy

[ngc891]

Hi all CVS specialists,

I´m a beginner at CVS, so forgive me if I'm asking nonsense.

I've imported a module "PI.0" into CVS.
Import has created a working branch as  "avendor" and a revision on it 
as "arelease".
The arelease files are all "1.1.1.1".

I've now checked out my working directory as "avendor", my working 
branch. I've now changed one file (say one t.c) from "1.1.1.1" to 
"1.1.1.2" and committed that to the working branch "avendor".
The I've tagged this new revision to "brelease".

My problem now is, how to convert this new release "brelease" to the 
"Root"-Branch (that is something 1.*)!
What is the name of the Root-Branch? I've never been asked to create 
one. And the graphical display doesn't show a name corresponding to 
revision 1.1.

The essential question is:
HOW COULD I CREATE A NAME FOR THE ROOT BRANCH???

What I want to see is revisions 1.1 of all files for the "Root" and a 
revision "1.2" for the file "t.c", when I'm working "Root", whatever 
that is...

Thanks very much for yor help,
Fritz Bode
