Partial merge; aka magic tag for the trunk?

[J. Cone]

Hello All,

Appologies in advance if this is a silly question.

I have a file with a branch tag.  I have worked out that I can make another
tag that refers to the same branch (ie continues to refer to the file at
the end of it) by
  cvs admin -nBranchCopy:<magic tag>
eg                        1.2.0.2

This would let me back up a branch tag before I modify it.

Now I am hoping to make the original tag that refer to the trunk (ie
continue to refer to the latest non-branch revision).  Please tell me what
magic tag I should use.

So far I have tried:
  0.1  admin refuses
  1    admin dumps core, leaving locks which I have learned to tidy up

I am using CVS 1.10.5 on HPUX 10.20, via NFS.

[ The final goal is to merge some directories in a module back to the head,
and still have a tag for naming a consistent set of files including the
branched unmerged ones and the trunk merged ones.  I don't care whether
added files in the same directory as the merged ones are added on the trunk
or the branch; caring about that would make my head hurt too much :-) ]

Thank you,
James Cone.
