Abandoning head for branch?

[KEVIN ZEMBOWER]

There must be a way to do this, but I can't figure it out.

I have a file I've modified and checked in, up to version 1.3. I want to 
abandon r1.3, checkout r1.2, make changes to it and check it back in as r2.0 
and have it treated as the default head version from then on. How can I do this?

Ashwin Patil asked almost this exact question in the archives at 
http://mail.gnu.org/archive/html/help-rcs/2002-06/msg00012.html, but I couldn't 
find an answer to his question posted.

Thanks for your help.
