I wanted to create a release of both the Dark and Sodelicious themes, and had an interesting time doinf it.
There is a lot of information on the Drupal website, notably the CVS quick-start guide for module and theme maintainers (http://drupal.org/handbook/cvs/quickstart).
In short, I had to clean up all the branches I had mistakenly created by
cvs tag -dB DRUPAL-6--1
where DRUPAL-6--1 is the branch name to be deleted.
Following the quick start guide, I
cvs co contributions/themes/dark
cd contributions/themes/dark/
cvs update -dP -r DRUPAL-6--1
cvs tag DRUPAL-6--1-0
Hey presto!
I did the same for the 5.x branches and repeated the same again for Sodelicious.
Happy man.
